The São Paulo Railway Company (SPR, nickname Ingleza, transl.: The English[1]) was a privately owned British railway company in Brazil, which operated the 1,600 mm (5 ft 3 in) gauge railway from the seaport at Santos via São Paulo to Jundiaí. The company was nationalised in 1946 and became the Estrada de Ferro Santos-Jundiaí.

The São Paulo Railway consists of three parts:

Three different systems have been used to climbs the steep grade between Piassagüera and Paranapiacaba:

  • A four section cable railway with stationary steam engines, in use from 1867 till 1970, called Serra Velha, transl.: Old Mountain
  • A five section cable railway with stationary steam engines, in use from 1901 till 1982, called Serra Nova, transl.: New Mountain
  • An electrified Rack-and-adhesion railway built on the right of way of the abandoned Serra Velha opened in 1974, called Systema Cremalheira-Aderência, transl.: System Rack-and-adhesion

Planning[edit]

In 1859, a group of people led by the Barão de Mauá convinced the Brazilian government that it was important to construct a railroad connecting São Paulo to the seaport at Santos. The main purpose of the project was the transport of the coffee grown on the inland plateau to the Atlantic coast for export. The biggest difficulty was the task to overcome the steep east slope of the 800 meter high Serra do Mar, which was considered to be nearly impracticable. Therefore Barão de Mauá asked England to clarify the feasibility of a railway line for locomotive hauled trains within a budget limit of 200,000 £. The biggest technician for this subject was consulted: the Scottish railroad engineer James Brunlees.[2][3]

Brunlees visited Brazil and considered that the project was feasible. He recommended the engineer Daniel Makinson Fox to Barão de Mauá for the execution of the project. Fox was at that time only 26 years old but had experience in the construction of railways through the mountains of northern Wales and the hillsides of the Pyrenees. He realised that the railway can only climb the slope in the Serra do Mar if a 5 miles (8.0 km) long incline system is built. An adhesion railway would have used 26 miles (42 km) to overcome the slope and would have also overrun the 200,000 £ budget.[3]

Construction[edit]

Daniel Fox's proposal for the railway line from Santos to Jundiaí including the incline system was approved by Brunlees and the São Paulo Railway Company (SPR) was established to build the railway system and operate it for 90 years.[4] Since the capital of the company was mainly British also the official company name was in English, not Portuguese.

Construction on the 20 km long adhesion railway Santos - Piassagüera began on March 15, 1860 and on the incline system in the year 1861.[4]

The road was constructed without explosives, since it was felt that the slopes are very unstable. The rock was excavated only with plug and feathers. Embankments of 3 to 20 m in height were constructed to protect the tracks from the frequent torrential rains in the area, which used about 230,000 cubic metres (8,100,000 cu ft) rocks. The line did not have any tunnels.[3]

In spite of all the difficulties, the construction finished 10 months ahead of the date specified in the contract, which was eight years. The São Paulo Railway was opened on 1867-02-16.[3]

Serra Velha - the first incline system[edit]

Brake van, which was used to attach the standard railway wagons to the cable of the Serra Velha incline system between Piassagüera and Paranapiacaba

The part of the route climbing the Serra do Mar consisted of four 10.3% grade cable railway sections with the following length:[2]

  • section 1: 1,781 metres (5,843 ft)
  • section 2: 1,947 metres (6,388 ft)
  • section 3: 2,096 metres (6,877 ft)
  • section 4: 3,139 metres (10,299 ft)

At each section the wagons were attached to a steel wire rope with the help of a special fitted brake van called Serrabreque (transl.: Hill Brake).[5] The steel cables was driven by a stationary steam winding engine at the top end of the section, where also a 75 metres (246 ft) extension with a 1.3% grade was fitted, so that the wagons could be led to the next section.[2]

The incline system was later called Serra Velha (transl.: Old Mountain) to distinguish it from the later built second incline system called Serra Nova.

Serra Nova - the second incline system[edit]

The large volume of coffee shipments and the growth of the cities in the São Paulo region required more transport capacity. Therefore construction of a second incline system started in 1895. The new line runs parallel to the already existing one in about two miles distance. It had five sections using continuous steel wire ropes which were moved by stationary 1,000 hp steam engines. Each section was about 2,000 metres (6,600 ft) long and had a grade of 8%. Two to three wagons have been coupled to the rope with the help of small locomotives fitted with grip engaging with the cable. These locomotives were also able to handle the wagons in the terminal station and between the sections, so that the operation of the incline system was facilitated. The locomotives have been called Locobreque (transl.: Locomotive Brake). In case the weight of the wagons to be lifted was to heavy compared to the wagons lowered at the same time, tank cars filled with water where used to counterbalance the system. The incline system was used in revenue service till 1982.[4]

Protests[edit]

In 1889, the first protests were made against the British monopoly over the route to Porto de Santos, which culminated in the construction of Mairinque-Santos in 1910, for Estrada de Ferro Sorocabana.

Nationalisation[edit]

On 1946-09-13, the railroad was nationalised by the Brazilian government, and renamed the Estrada de Ferro Santos-Jundiaí, and on 1948-09-27, it was merged with most of the other Brazilian railways in to the Rede Ferroviária Federal, SA (RFFSA).

Systema Cremalheira-Aderência - the Rack-and-adhesion railway[edit]

In the 1970s (well after it had been renamed), the haulage system was replaced by an Abt rack system which was installed by the Japanese firm Marubeni. The locomotives for this changeover had been constructed by Hitachi with the help of SLM and are working with 3 kV DC supplied by an overhead lines.
