1) The LNER would have almost certainly gone into liquidation. Remember it was the one which was dealt a massive blow to its business by the Depression and it never really recovered from that. Its operations might have been forced to merge with the LMS.
2) The LMS would have continued, but probably in a scaled back form - they might have been forced to handover their Welsh operations to the GWR and their operations in West Yorkshire to the LNER for instance.
3) The GWR would have continued in much the same form as before - as even as late as 1947, the company was still making handsome profits.
4) The Southern would have continued, because its operational model was very close to that adopted by the rest of the British rail network in the later half of the 20th century (i.e. a preference for electric traction and the fact that most of the Southern's revenue came from passenger services).
Nice to go back to the original topic of this thread!
My take is that I would suggest that one can predict a likely alternative history for the Big 4 for a maximum of possibly 10 years after the end of the war. After that other social and economic changes in Britain would have changed the rules of the game sufficiently that any prediction of what the ‘Big 4’ would have done after about 1955 would be no more than guesswork.
Some assumptions for the first ten years:
- the ‘Common Carrier’ obligation for freight traffic would have been abandoned by the end of 1945
- at the same time the influence of the Traffic Commissioners on fares and rates would have stopped
- the growth of car ownership would have been the same as real history
- employment levels would have remained as they really were
- the country’s economic condition would not have been significantly different from that which really happened.
Dropping the Common Carrier obligation would have meant that it became useful and necessary to have a proper management accounting system which could allocate costs and revenues to particular activities. This would then have helped the businesses to have concentrated their resources where they would make the best return. The costs of running lightly used lines and of operating the heavy daily traffic around the large cities for 4 hours a day would have become clear. The railways would have had a proper understanding of their revenues and costs by 1948 or 1949 at the latest - 15 years before Beeching.
What certainly would also have had to have happened for the Big 4 to survive was that the return on capital would have had to have been greater than that pertaining at the end of the 30s (around 2% to 2.5%) in order to attract investment capital. The effects of the Common Carrier obligations, the rate-setting by the Transport Commissioners and the after-effects of the Depression meant the railways were starved of investment funds.
The financially weakest of the ‘Big 4’, the LNER, had proposed a ‘Landlord and Tenant’ structure - it would sell its network to the Government and pay rent to run its services over it. (This sounds very much like the structure adopted 50 years later…!) If the LNER could have got rid of much of its excessive infrastructure where heavy industry had suffered badly in the 1920s and 30s, it might have been able to survive as a company. Alternatively it could have regrouped as two companies - one with the profitable parts and either closed the other or sought other sources of funds from local or central Government.
I suspect that the other three would have continued much as before - transport conglomerates operating trains, road coaches and buses, lorries, hotels, ferries and airlines and developing those fields which gave the best return. I could well see the GWR, using its experience in selling holidays in Devon and Cornwall, being an early player in the package holiday boom to Majorca with GWR-branded DC3s!
I don’t know what would have happened to loss-making suburban services - either the railways would have put up their prices and priced themselves out of the business or, with increasing car ownership and congestion, the city authorities might have come up with something like the Public Services Obligation subsidy 20 years earlier.
Certainly many short, dead end, branch lines would still have closed, but as railwaymen liked running trains I suspect that more efficient ways of operation would have been found for many secondary lines. Whether this would have saved any or all of them in view of the doubling of the number of private cars between 1950 and 1960, I can’t guess.
All the railways were already investigating alternative forms of traction, the LNER had planned the Woodhead and Shenfield electrifications and was proposing a build of mainline diesel locomotives; the GWR had built branch and mainline diesel railcars, had studied the electrification of the lines in Devon and Cornwall and the use of the power of the future, the gas turbine; the LMS had built diesel shunters, mainline diesel traction, diesel railcars and operated electrified lines; the Southern had invested widely in electrification and adopted more efficient ways of using its rolling stock. I would have expected these trends to have continued and the construction of steam locomotives to have ceased by 1952 or 1953.
For the next attempt at alternative history - what if William had lost in 1066?
