London Underground 1914 Tube Stock

This stock was built for the Baker Street & Waterloo Railway (later the Bakerloo Line) which had expanded North from Edgware Road to Paddington in 1913 and a further extension to Queen's Park was due in 1915 [1]. The 1914 Tube Stock consisted of twelve new Driving Motors and two new trailers with other trailers rendered surplus by the Piccadilly moved across to the Bakerloo.

Number built: 14 (12 Driving Motors and 2 Trailers)
Built: 1914
Builder: Brush / Leeds Forge
Motor: 2 GE212 electric motors per car 

The new trains introduced a number of new features. Although they retained the end of car gates as earlier tube stock they also had hinged centre doors. These were still hand operated though had electric locks and safety mechanisms to prevent the train starting before the door had closed. They also had improved interiors and better riding thanks to anti-vibration material fitted under the springs [2]. Unlike earlier tube stock they did not have a clerestory roof to retain heat in the winter.

They also had emergency lighting powered by an onboard battery in the event of current loss. They were also the first tube stock to have interpole electric motors which reduced sparking and improved reliability. They had automatic acceleration [3].

The cars were of all steel construction built by Brush (ten driving motors) and Leeds Forge (two driving motors and the two new trailers) [4]. The tube stock remained in service until the mid-1930s when it was withdrawn.
Brush built DM 43 [2]
