Return to the Underground
Back at the Underground Group, Stanley returned to his role as managing director and also became its chairman, replacing Lord George Hamilton. In the 1920 New Year Honours, he was created Baron Ashfield, of Southwell in the County of Nottingham, ending his term as an MP. He and Pick reactivated their expansion plans, and one of the most significant periods in the organisation's history began, subsequently considered to be its heyday and sometimes called its "Golden Age".
The Central London Railway was extended to Ealing Broadway in 1920, and the Charing Cross, Euston and Hampstead Railway was extended to Hendon in 1923 and to Edgware in 1924. The City and South London Railway was reconstructed with larger diameter tunnels to take modern trains between 1922 and 1924 and extended to Morden in 1926. In addition, a programme of modernising many of the Underground's busiest central London stations was started; providing them with escalators to replace lifts. New rolling stock was gradually introduced with automatic sliding doors along the length of the carriage instead of manual end gates. By the middle of the 1920s, the organisation had expanded to such an extent that a large, new headquarters building was constructed at 55 Broadway over St James's Park station. In this, Ashfield had a panelled office suite on the seventh floor.
Starting in the early 1920s, competition from numerous small bus companies, nicknamed "pirates" because they operated irregular routes and plundered the LGOC's passengers, eroded the profitability of the Combine's bus operations and had a negative impact on the profitability of the whole group. Ashfield lobbied the government for regulation of transport services in the London area. Starting in 1923, a series of legislative initiatives were made in this direction, with Ashfield and Labour London County Councillor (later MP and Minister of Transport) Herbert Morrison, at the forefront of debates as to the level of regulation and public control under which transport services should be brought. Ashfield aimed for regulation that would give the UERL group protection from competition and allow it to take substantive control of the LCC's tram system; Morrison preferred full public ownership. Ashfield's proposal was fraught with controversy, The Spectator noting, "Everybody agrees that Lord Ashfield knows more about transport than anyone else, but people are naturally loth to give, not to him, but to his shareholders, the monopoly of conveying them." After seven years of false starts, a bill was announced at the end of 1930 for the formation of the London Passenger Transport Board (LPTB), a public corporation that would take control of the UERL, the Metropolitan Railway and all bus and tram operators within an area designated as the London Passenger Transport Area. As Ashfield had done with shareholders in 1910 over the consolidation of the three UERL controlled tube lines, he used his persuasiveness to obtain their agreements to the government buy-out of their stock.
I have read this bill carefully, and I beg you to accept that I know what I am talking about. You cannot conceive I would be guilty of such folly as to suggest to you in a matter in which my whole life has been wrapped, that you should transfer your interests to a board subject to political interference, that could play ducks and drakes with your investments. Acts of Parliament are not treated like scraps of paper. They are scrupulously observed by all parties. I have promised the Minister my support. You may fail to support me, but in that event you will have to find somebody else to manage your undertakings. I have pledged my word and I am not going back on it.
The Board was a compromise – public ownership but not full nationalisation – and came into existence on 1 July 1933. Ashfield served as the organisation's chairman from its establishment in 1933 on an annual salary of £12,500 (approximately £600,000 today), with Pick as Chief Executive.
The opening of extensions of the Piccadilly line to Uxbridge, Hounslow and Cockfosters followed in 1933. On the Metropolitan Railway, Ashfield and Pick instigated a rationalisation of services. The barely used and loss-making Brill and Verney Junction branches beyond Aylesbury were closed in 1935 and 1936. Freight services were reduced and electrification of the remaining steam operated sections of the line was planned. In 1935, the availability of government-backed loans to stimulate the flagging economy allowed Ashfield and Pick to promote system-wide improvements under the New Works Programme for 1935–1940, including the transfer of the Metropolitan line's Stanmore services to the Bakerloo line in 1939, the Northern line's Northern Heights project and extension of the Central line to Ongar and Denham.
Following a reorganisation of public transportation by the Labour government of Clement Attlee, the LPTB was scheduled to be nationalised along with the majority of British railway, bus, road haulage and waterway concerns from 1 January 1948. In advance of this, Ashfield resigned from the LPTB at the end of October 1947 and joined the board of the new British Transport Commission (BTC) which was to operate all of the nationalised public transport systems. At nationalisation, the LPTB was to be abolished and replaced by the London Transport Executive (LTE). Lord Latham, a member of the LPTB and the incoming chairman of the new organisation, acted as temporary chairman for the last two months of the LPTB's existence. The BTC required office space, and as one of his last acts before leaving the LPTB for the BTC, Ashfield offered the use of the eighth and ninth floors of 55 Broadway for the BTC's use. He was in turn allotted a BTC office on one of these floors, but decided to continue using his seventh-floor suite for his BTC duties. Latham, as his replacement at the LPTB (and subsequently the LTE), was not able to occupy this accommodation until Ashfield's death.
