Haven’t looked on here for a looong time.
Acton Works Lifting Shop image – soon after opening. With extra edits and corrections from additional quick research, the Shop opened for business in 1928, and the car to right has body profile and general appearance that probably best suits LNWR & LER Joint Stock (colloquially “Watford Joint Stock”), with a further clue in the single centre door that looks to be of the swing door inset type.
For efficiency, another rapidly complied footnote, having now seen Post 21 on
24 February 2023:
The post’s upper image is assumed to be the same occasion as the District train in the lower image, and may be early 1930s.
Location is High Street Kensington, trains occupy Inner Rail platform (used by anti-clockwise Circle trains). Mid-platform foot bridge is the location clue, slightly helpful archive image available:
B/W print; View of a section of District/Circle line platform at High Street Kensington by Topical Press, 3 Dec 1936 | London Transport Museum (ltmuseum.co.uk)
Train in upper image is 4-car Metropolitan Railway stock, seems to be all clerestory cars, Motor Car at rear is probably 200Hp-motored for a Circle working. Train number 350 (looks like LT-style numerals) is not in a Circle series either Met or LT, may be an unusual service or a disrupted service temporarily displaying a Crew Duty number.
Leading car is Metropolitan Saloon Stock 1904 build (distinguished by narrow bodyside windows) First Driving Trailer (1DT), end vestibules with the most common small lookout windows arrangement (some other builds of 1DT had distinctive different). First Class car from new, one of 20 cars (1-20 in Driving Trailer series). Leading end only shoebeam confirms this. Gate-ended car when new, end vestibules added later, mostly 1906-7.
The (apparently light-colour) numeral 1 on bodyside door glass and some side lights indicates First Class – these numerals are relatively uncommon in 1930s images. Not visible but there will also be a white on black oval “First Class” on some side lights – a style added in the 1920s. Some cars of this type had improved interior finish, done around 1930 but unlikely here given the apparent older style of class designation. Other cars from the original group were re-equipped from around 1929 to run as Driving Trailers with M-V motor coaches. If not an Improved Interior car, leaves only a small number of candidates (I speculate 1DTs 7, 13, 14, 20 which faced the Down direction, as here,
Another small footnote to add.
The Acton image is typical of several taken in the early years of the Works. The Underground Group used picture agencies a great deal when needing images for record as well as publicity. Topical Press was one favourite. Maybe this image and others were copies either retained by a photographer or perhaps purchased from an agency for use? - much as we would purchase from the modern online agencies.
