The Serpell Report was produced by a committee chaired by Sir David Serpell, a retired senior civil servant. It was commissioned by the government of Margaret Thatcher to examine the state and long-term prospects of Great Britain's railway system. There were two main parts to the report. The first (and lengthier) part described in detail at the state of British Rail's finances in 1982. The second part looked at various options for a future (1992) rail network, and made comparisons between each option and the continuing the existing network.
In many ways, 1982 represented the nadir of Britain's railways. That year saw the lowest number of passenger journeys of the second half of the 20th century, the lowest level of passenger-miles, and the lowest (real) level of passenger revenue since 1968. Although these figures were partly the result of the 1982 strike (over rostering arrangements), rail passenger numbers had been in steady decline since 1957. (Only 1978–1980 saw consecutive years of passenger growth). In 1982 terms, revenues had decreased steadily from £2,300 million in 1970 to £1,800 million in 1982, while costs had risen from £2,500 million to £2,700 million. Consequently, BR's deficit had increased by a factor of 4.5.
For reference, in 1982, journeys totalling 18,300 million passenger-miles were made; the network comprised 10,370 route miles; and BR's passenger deficit was £933 million. The various options for the network considered in Part 2 were as follows:
- Option A was a "commercial" network, in which the railways as a whole would make a profit. This scenario would have seen the route mileage reduced by 84%, and annual passenger-miles reduced by 56%. The only main lines left would have been London-Bristol/Cardiff, London-Birmingham-Liverpool/Manchester-Glasgow/Edinburgh, and London-Leeds/Newcastle. Some major commuter lines in the southeast would have been retained; all other lines would have disappeared completely. The passenger sector would still make a small loss, but this would be offset by profits from the freight sector.
- Option B was similar to Option A, with allowances for the cost of congestion caused by removing rail links. If the removal of a line in Option A would cause a greater cost to the country in terms of increased road congestion than would be saved in removing the line, then the line was retained under Option B. This scenario would have seen the route mileage reduced by 78%, and annual passenger-miles reduced by 45%. The network would have been as per Option A, but with the addition of most of the London commuter lines, plus the London-Westbury section of the Great Western Main Line.
- Option C was actually a set of three options, each designed to reduce the railways annual deficit according to a given target:
- Option C1 would have kept the existing network more or less entirely, only removing the most loss making services. While the network would have been virtually unchanged (at 99% of existing length), many smaller stations would have closed. One lengthy removal would have been the Westbury-Weymouth line. Passenger-miles would have been reduced by about 4%.
- Option C2 was designed to reduce the annual deficit to £700 million. Loss making services would have been cut (using a harsher test than Option C1). There would have been some more network cuts, such as the Trowbridge-Melksham-Chippenham line, the branches north of Norwich, the north Devon line from Exeter towards Barnstaple, the line between Swansea and Stokesay, and the mid-Wales branch west of Shrewsbury. However, most of the savings would have come from service cuts and station closures. This scenario would have seen the route mileage reduced by 17%, and annual passenger-miles reduced by 9%.
- Option C3 was designed to reduce the annual deficit to £500 million. Major cuts would have included all lines in Wales apart from the valley lines north of Cardiff; all lines in Devon and Cornwall other than the main line link to Exeter; the Salisbury-Exeter line; all lines in East Anglia other than the line to Norwich; all rural lines in Scotland; the trans-Pennine line; and most local lines east of the East Coast Main Line. This scenario would have seen the route mileage reduced by 39%, and annual passenger-miles reduced by 15%.
- Option D was the only option not designed to meet a financial criterion. Instead, connections would have been made to retain services to communities with population greater than 25,000. This came out very similar to Option C2, with only 11 extra communities served.
The report also briefly considered an Option H – a "high investment" option. This looked at the effects of new rolling stock on maintenance costs, and concluded that the return would be far too small.
Otherwise, the report did not seriously examine the effects of improving rail services.
The report was portrayed by rail supporters as a "second Beeching", was not taken up by the government, and did not result in any network changes. Passenger numbers picked up through the mid and late eighties, reaching a 20-year high in 1988, and have continued to grow since.
