Mont Cenis Pass Railway
The Mont Cenis Pass Railway operated from 1868 to 1871 (with some interruptions) during the construction of the Fréjus Rail Tunnel. It was the first mountain railway in the world. It was designed by John Barraclough Fell and his three-rail design was used on some other mountain railways. The railway was 77 kilometres (48 miles) long, with a gauge of 1,100 mm (3 ft 7 7⁄16 in) and a maximum inclination of 9 per cent. It was used to transport English mail to India as part of the 1400 mile All Red Route.
A British company, the Mont Cenis Railway Company was established by a number of British contractors, engineers and investors to build the railway. These included: Thomas Brassey, Fell, James Brunlees and Alexander Brogden. Although it would eventually be superseded by the tunnel, they believed that, during its life the cost of the pass railway would be repaid with a profit to them.The company used British engine-drivers and workmen.
In the event there were delays in establishing the railway and it did not start until 15 June 1868. On the other hand the tunnel progressed faster as new tunnelling methods were developed so that it was opened on 16 October 1871. This meant that the pass railway was active for a shorter time than expected, leaving the proprietors with a considerable loss. However the technology proved itself and was used on a number of other mountain railways.
Until this railway was built, rail passengers had to cross the Alps by horse-drawn diligence in summer or sledge in winter.
The Pass Railway is sometimes called the Mont Cenis Summit Railway so as to distinguish it from the Tunnel Railway.

By the early 1860s most of a 1400 mile rail connection between Calais and Brindisi had been built, much of it by Thomas Brassey and John Barraclough Fell. The only major remaining problem was the crossing of the Alps. Work on the Frejus or Mont Cenis tunnel had started in 1857 but it looked as though it would take many years to build, using traditional tools and gunpowder.
A full rail service from Calais to Brindisi, continuing by sea to Alexandria, would take about 30 hours off the journey time from Britain to India, China and Australasia compared with the current option of Calais to Marseilles by rail and onwards by sea. The increasing volumes of trade, in mail, passengers and goods presented a tempting prospect of profits to be made by crossing the Alpine barrier as well as an opportunity to strengthen the ties of Empire. In 1866, at a British Association meeting, Fell reported how four years earlier he had been asked to design some means of improving on the existing horse-drawn transport across the Alps over the Mont Cenis Pass. The slopes and curves were too much for a conventional train and so far no such railway had been built anywhere but Fell managed to design a suitable system and he patented it. He set a maximum gradient of 1 in 12 (8.3%) and a minimum curve of 2 chains (40 m). The French and Italian governments had agreed to the idea subject to satisfactory testing. The detailed design was carried out by A. Alexander at Brassey Jackson Betts & Co.’s Canada Works in Birkenhead. The gauge was 1,100 mm (3 ft 7 7⁄16 in).
Experiments on the new locomotive were carried out in 1863/4 near Whaley Bridge on an incline of the Cromford and High Peak Railway by permission of the lessees the London and North Western Railway. Early experiments were private but public experiments took place in January. They showed that the light locomotive would not work on the 1 in 12 slope without the central rail drive but could tow four wagons weighing 7 tons each with it.
Permission to Build
With this information, the Mont Cenis Concessionary Company was formed on 12 April 1864 to obtain concessions from the two governments to build a railway on the public road over the pass until the tunnel should be opened. The subscribers were: The Duke of Sutherland, Thomas Brassey, Sir Morton Peto and Edward Betts, James Lister, Thomas Crampton, Alexander Brogden, James Cross, Fell, James Brunlees, Joseph Jopling, T S Cutbill and C. Lowinger. Each took one share at £1,000 except that Brassey took three, Fell took two and Peto and Betts took one between them.
On behalf of the company Fell approached the French and Italian governments for permission to build the railway. The governments would not be asked for any money. The company expected to make a profit. The French government wanted more proof that the scheme was practicable. The Italians said they would grant permission if the French did. To provide additional evidence a second test line was constructed along the zig-zag section from Lanslebourg to the summit. It was 1¼ miles long with a ruling gradient of 1 in 12 and an average of 1 in 13. It started at 5,321 feet and rose to 5,815 feet. Rails were borrowed from the Victor Emmanuel Railway. This test line was completed by 23 January 1865.
Meanwhile a second locomotive was built by James Cross of St Helens and was the first engine to be sold by him. It was designed by Alexander after consultation with Fell. Cross was probably used because Brassey’s works was very busy.
The trials were observed by officials from the governments of France, Italy, Great Britain, Austria and Russia. There were 600 spectators. The British representative was Henry Whatley Tyler. Trials began on 28 Feb 1865. Only the first locomotive was available but the trials were very successful. Captain Tyler came again in the spring when locomotive 2 had arrived. He found that some parts of this locomotive needed strengthening and it would not be advisable to test it very much until replacements had been obtained. However he did test it successfully.
The trials gradually moved towards several runs on each day. On 19 July they were observed by the Frederick Hardman from the Times and the French commissioners made the last of six visits. There were three more days of trials for the Italians and the Russians and a special day for James Brunlees on 31 July. This ended the official tests but private testing continued until the end of November. The French concession was granted on 4 November 1865 and the Italian on 17 December.
Mont Cenis Railway Company
On the 7 February 1866 the Mont Cenis Railway Company (Limited) (MCR) was established as company 2820c under the Companies Act 1862. There were 12,500 shares of £20 each. For each share £1 was to be paid on application, £3 on allotment and further calls of £4 would be made at intervals of not less than three months.
The directors and other officers of the company were: The Duke of Sutherland (President), Sir James Hudson (Chairman), Thomas Brassey, The Duke of Vallombrosa, Lord Abinger, Sir Morton Peto, Sir Robert Dallas, Edward Blount, Jervoise Smith, Thomas Crampton, W B Buddicom, Alexander Brogden, Fell, James Brunlees (Engineer) and T S Cutbill (Secretary). By October Cutbill had been replaced by W.J.C.Cutbill.
In August the directors found that they each had to take up five more shares for the company to qualify for the London Stock Exchange. By 21 Aug 8,678 shares had been taken up by 448 shareholders. Among these, Brassey took 945, Brogden 792, the Duke of Sutherland 542, Abinger 292, Brunlees 137, Crampton 237, and Fell 242.
In early 1866 detailed plans and sections were drawn up for submission to governments. Construction began in March. The railway was to be 79.2 km long. Out of the 10 metre standard width of the road the company was allowed 4 metres and the governments retained 6 metres for roadway. Much of the road was built on a shelf. This had to be checked and strengthened or widened in places. A wooden fence had to be built to separate animals on the road from the railway. At villages the railway had to leave the road and use a separate right of way. At some hairpin bends adjustments had to be made to meet the railway’s minimum radius of 40 metres. On the Italian side the road had been built with a gentle slope. This had proved too prone to avalanches and replaced by a steep zig-zag called Les Echelles (the ladders). The railway used the original road because the ladders were too severe for it. It needed 600 metres of masonry avalanche shelter. Using the Michelin map, the rise from St Michel is 4,492 feet and from Susa 5,178 feet. J. B. Fell was appointed ‘Managing Director at the Mont Cenis’. It looks as though direct labour was used on the French side. On the Italian side the contractor Gianoli & Canova was used.
Fell had intended to have two classes of locomotives: one to pull heavy loads slowly up steep slopes from Lanslebourg and Susa and one to run faster on easily graded sections between Lanslebourg and St Michel. He was over-ruled by his co-directors. A. Alexander was appointed Locomotive engineer and Brassey’s Canada Works had quoted to build the locomotives. The directors then discovered that French law prohibited importation of foreign machinery subject to a French patent. Fell had taken out at least one French patent. At this late stage the most reputable French manufacturers were busy so they used Ernest Goüin et Cie. of Paris even though Alexander had reported on them unfavourably. In August the locomotives were expected to be delivered in February, March and April 1867. The locos were designed by Alexander and his designs were passed by the board. The rolling stock was built by Chevalier, Cheilus & Cie of Paris.
At the beginning of September 1866 Abinger, Brogden and Vallambrosa visited the works. They found: 2,200 men employed, rails being laid at both ends and on the plateau of the line and a scarcity of horses owing to the Austro-Italian war. On the French side the stones comprising the foundation of the road were so large that blasting was required to make holes for the fence. The locomotives might possibly be an issue. Otherwise nothing seemed likely to delay them.
It had been a cool summer so the ice had not melted as much as usual. On 25 September, after a few days of warm rain, a tributary to the river Arc swept debris into the main river where it formed a dam, creating a reservoir. When this dam finally burst, there was a deluge which caused damage at fifty places between St Michel and Termignon.
Between Lanslebourg and Susa, all was well. The permanent way was nearly complete by early December, when snow stopped the work.
February 1867 General Meeting
On 19 February 1867, at the second half-yearly general meeting, shareholders were told that most of the line would be ready by May. On 4 March, Fell wrote to the board that he expected the line to open in September. On 4 April the board were told that locomotive construction was well behind schedule. The first loco should be ready by 1 May, the second in June, and the remainder to follow at the rate of one per week. The first carriage was ready apart from its wheels.
Board of Trade Inspection
In mid August the Board of Trade dispatched Captain Tyler to inspect the railway and the tunnel. On the way he inspected the locomotives and rolling under construction in Paris. On 22 August the repairs between St Michel and Lanslebourg were incomplete. However on 26 August a test run was attempted. Two Gouin locomotives had been delivered but were not yet ready for service. So they had to use the second of the two British-built engines, built by James Cross at St Helens. Alexander Brogden was present. He wrote an account of the test to the Duke of Sutherland which remains in the Duke’s records and is quoted verbatim by Ransom. Everyone was nervous because there had been no previous test. However the test was passed very well. Captain Tyler even composed a song. There were fifty people on the train and Brunlees was the driver.
Inspection of Tunnel
During the same visit, Brogden and Tyler investigated the tunnel. In the letter mentioned above Brogden reported that progress was good. The tunnel should be pierced in three years and completed in four – much earlier than previously anticipated. Tyler’s official report on the tunnel was that 7,366 metres had been bored, 4,884 remained and that the French had passed through the hard quartz and returned to the softer schist. The link between the tunnel and the French railway was another matter. It would not begin for a year and would take another four years to complete.
September 1867 French and Italian Regulators
The company asked the French and Italian regulators to come to an inspection on 20 September, with a view to open for freight as soon as possible and open for passengers in October. They were optimistic. However later in September they had a successful private test using the no. 3 locomotive, the first from Gouin . In October Brassey was touring his contracts. On the 12th he arrived at Mont Cenis expecting a successful test. It was a cold and wet day. The test was a disaster. Not only no. 3 but two other locomotives broke down in the attempt to complete the test. Brassey had to stand in the cold and wet, waiting for replacement engines. According to Helps, his biographer, Brassey developed a chill which led eventually to his death.
At a general meeting in November, shareholders were informed that Gouin had used inferior iron on the rocking shafts, rather than first grade iron or forged steel as specified, and the shafts therefore had failed in the test. Also the trailing axles could not accommodate the tight curves and would have to be removed. This meant that the rear driving wheels would need additional bearings and springs. On 17 April 1868 the Times reported that seven locomotives had had their shafts replaced or shortly would do.
Late Delivery of Rolling Stock
Chevalier were late in delivering the rolling stock. According to reports by Fell, Brogden and Barnes, 103 wagons were already being erected at St Michel in August 1867 but by February 1868 the company had only 2 of 11 first class carriages, 3 of 5 second class and 3 of 8 third class even though they were all due by the previous June. The delivered carriages were all four-wheelers and the missing ones were six-wheelers. When the line opened in June 1868, ‘’The Engineer’’ reported 7 first class carriages, 4 second class and 8 third class, officially a full complement but not so according to the internal information. In 1870, Fell reported that the six-wheelers ran more steadily and with less resistance so they did arrive.
There were financial problems. In March 1867 the board agreed to seek a loan of £60,000 against guarantees by directors. On 12 September The Times published an offering of £125,000 of 7 per cent debentures, adding that the line would probably open in October. No applications were received. However, to keep things going, Brassey guaranteed £15,000 needed immediately.
A general meeting in November authorised an increase in the company’s borrowing powers from £125,000 to £202,000 and an interest rate of 10 per cent. Liabilities were stated to be £182,000. £150,000 had been raised by shares and only £2,600 by debentures. It was decided to issue £200,000 worth of bonds at 10 per cent. The directors agreed to buy £150,000 provided the other shares subscribed £50,000. If this not happen within 14 days, the works were liable to be sold in discharge of the liabilities. Later more creditors were discovered, increasing the liabilities to £243,000. The company survived this crisis although the bonds may not all have been sold.
By November 1867, the line was complete except for St Michel and Susa stations and part of the covered ways. Barnes was employing 25 men. They included 4 good engine drivers, all British, 6 fitters working on engines, 3 blacksmiths and strikers for points and crossings, one fitter, one smith and one striker on wagon work. On 21 February, The Times reported that the line would open on 1 May but, once again it did not.
Testing & Final Opening April–June 1868
On 20 April, after a lot of work, a test train carrying 25 tons was taken from St Michel to Susa, returning the following day. On the 23rd another engine did the return journey within the day, taking 5 ½ hours to run the length including one hour of stoppages. A Franco-Italian commission did a thorough check 28 April to 2 May. They specified some interlocking but otherwise gave permission to open for goods traffic immediately with passenger traffic after 15 successful days of goods traffic.
The trial period was completed on 2 June. The promoters began to arrive in mid-May. At 11.30 on 23 May they enjoyed a celebratory journey from Susa to St Michel. The party of 54 included Blount, Brogden, Buddicom, Fell, Cutbill, Bell, Blake, Alexander, Barnes, Gohierre, Desbrière, Crampton, Count Arrivabene and Signor Milla the Italian government commissioner. The Times and the Morning Post were represented. The public opening was announced for 8 June.
Once again it did not happen but this time the problem was coordination with the main railways. The actual first passenger train ran from Susa at 7.20 am on 15 June 1868.
By 1 April, the tunnel boring amounted to 8,159 metres with 4,061 to go.
The completed Line
The line had cost £392,000 to build or £7,966 per mile. Brunlees had estimated £8,000 per mile. When passengers arrived at St Michel by the Paris-Lyon-Marseille (PLM) Railway, they had only to cross the platform to get on to the Fell railway train. Typically this had a Gouin locomotive, a guard’s van, a goods van, and three coaches. The crew comprised: driver, fireman, chief guard and two brakesmen, one to each coach. There were no continuous brakes. The Westinghouse brake was patented in 1872.
Trains left Susa at 7.20 and 8.30 am. These trains arrived at St Michel at 11.45 am and 12.55 pm. The journey time was 5 hr 15 min because French time was 50 minutes behind Italian. The 8.30 train had a connection that left Turin at 5.30 am. Return trains left St Michel at 1.15 and 3.55 pm.
On the opening day the 7.20 comprised one 1st, one 2nd and 3rd class coach with two fourgons. The 8.30 coaches were all 1st class, also with two fourgons. They both arrived slightly early.
Travel by the train saved 6 hours over the diligence, the coaches were more spacious and comfortable and even the 1st class fare was 20 francs cheaper. 29 passengers arrived by the PLM. 24 used the new train and 5 used the diligence. The diligence service declined but in 1871 there was still one a day.
Floods August 1868
Mail was carried from the start. From 1 August the French, Italian and MC Railways were coordinated so as to deliver mail a day earlier and book passengers right through but on 10 August a torrential storm washed away a length of road, leaving the rail suspended. Then on the night of 17/18 August the Arc flooded again and washed away the Pont de la Denise, partly because of spoil left by tunnel builders for the standard railway. Footbridges were used to allow passengers to walk over the breaks.
The MCR was reopened in late September but the PLM took longer and diligences were used between St Michel and St Jean for several more weeks. The PLM was glad of any excuse to divert its passengers from Mont Cenis to Marseilles. However the MCR was popular even when there were problems.
At this time there was no general manager on the spot and the two principal officials Gohierre and Barnes didn’t get on. So the board appointed James Anderson Longridge (1817-1896), son of Michael Longridge, an associate of George Stephenson to whom James himself had been apprenticed. Once again several locomotives required new cranks. More and better engines were needed although the company could ill afford them.
In August 1868 T.R.Crampton went to Mont Cenis to get Barnes’ approval on a new locomotive design. In mid-November four engines were on order from Cail et Cie, a manufacturer who had built Crampton-designed engines for the French mainline companies in the 1850s. They were to be “hired on the deferred purchase principle” as the directors’ report put it.
Snow Blockage November 1868
From 7 to 10 November 1868 there was a heavy fall of snow and also a locomotive broke down. The covered ways were still incomplete despite the pleas from Bell. This led to some delays but only one train was cancelled. In March 1869 a train was blocked by snow drifts. The mail was carried on by sledge but this too was overwhelmed by an avalanche. The driver escaped but it took two days to recover the mail.
General Meeting February 1869
At a general meeting in February 1869 the operating accounts from 15 June to 31 October 1868 showed that the expenses were 73 per cent of receipts. However the Balance Sheet for 31 October 1868 showed shareholders funds: £155,550, debentures £180,750, loans £17,500 and creditors £65,487. Creditors in France had agreed to defer payment, secured against the operating profit. The likelihood of the shareholders getting their money back was slim. The Duke of Sutherland and Jervoise Smith resigned. The Duke, having presided over a failure, may have felt that honour required his resignation. Furthermore he was chairman of the Sutherland Railway. This too had run out of funds after opening from Bonar Bridge to Golspie in April 1868. He himself funded the next section. Brassey kept in touch with the MCR and provided funds when the creditors got difficult.
In 1869, weekly receipts increased fairly steadily from £700 to £1700 before dropping to £1000 during the winter. Edward Whymper used the railway in 1869 and he describes the journey in his book Scrambles amongst the Alps. A test Indian Mail delivery was carried on 15 October. It arrived at Susa 67 minutes late but the MCR clawed back 57 of them. It soon became a regular service.
The average speeds of trains were: St Michel and Lanslebourg: 13.2 mph both ways; Lanslebourg and La Frontière 7.9 mph upwards and 10.6 downwards; La Frontière and Susa 10.6 mph downwards and 6.6 upwards.
The Cail locomotives arrived in winter 1869/70. This enabled them to run freight trains on a regular basis. Traffic included coal and materials for the tunnel entrance at Bardonècchia. In the AGM on 10 February 1870 the board were unable to promise during 1870 to pay interest to bondholders or shareholders as traffic was still below expectations.
In July 1870 there was a petition to wind up the company and J. A. Longridge was appointed provisional liquidator. The railway continued to run but trade was hampered by the Franco-Prussian War and the revolution in September. Paris was a major source of traffic and the siege of Paris reduced traffic by two thirds.
The tunnel breakthrough took place on Christmas Day 1870. The first train ran through the tunnel on 16 Sep 1871. The tunnel service started on 16 October 1871 and the MCR service ended on the previous day. The MCR began to run at a loss in 1871. They applied to the Italian government for a subsidy but this was refused. At the same time they could not stop the service because of the concession agreement.
During the life of the railway: no passenger met with an accident; in December 1869 two men were killed when a freight train was derailed; in 1868 an employee was thrown from a train and killed. In September 1870, Fell reported to the British Association that: trains had travelled 200,000 miles and carried 100,000 passengers; the Indian Mail had never missed a connection and had taken 30 hours less than before; the journey time from Paris to Turin had been cut by one night. The MCR had proved the value of Fell’s new system.
After the line was closed, Longridge worked out that the total train-miles were 345,500. Working expenses per train-mile were 9s. 8½d of which locomotives cost 4s 0d. Receipts were 11s 9½d
When Fell gave a paper to the British Association in 1870, the impressive progress of the tunnel led him to predict correctly that it would open before the end of 1871. The Cantagallo Railway was already under construction. Central rail railways were being mooted in India, Switzerland, Spain and additional railways in France and Italy.
After the MCR closed, much of its material and some staff went to the Cantagallo Railway and the Lausanne-Echallens Railway. Records in the Public Record Office do not show how the proceeds were shared among the creditors or whether the shareholders got any of their investment back. Longridge retired in 1881 and died in 1896. If he completed the liquidation he did not report it to the Companies Office.
Other Fell Railways
Once the railway was opened, Fell rapidly moved on to develop the Cantagalo railway, near Rio de Janeiro in Brazil. It ran from Niterói to Nova Friburgo. It re-used some of the equipment from the Mont Cenis Pass Railway, and was to the same gauge of 1100 mm. It opened in 1873. Brazil's first mountain railway, it operated until the 1960s.
The steepest gradient was 1 in 11 and the sharpest curve 1.4 chains. With these sharp curves, the rigidly fixed horizontal wheels did not follow readily irregularities in the centre rail. Fractures were frequent. In 1883 powerful conventional 0-6-0Ts from Baldwin replaced the Fell engines. However the central rail was still used for braking.
