In 1933, the Metropolitan Railway was absorbed into the newly established London Passenger Transport Board. From this point on the title of the Centre changed to London Passenger Transport Board (Metropolitan Line Centre). From 1946, the Centre's title changed to London Passenger Transport Board (Railways) Centre, and from 1948 the Centre was titled London Transport Executive (Railways) Centre. The Centre closed on 31 December 1948. Following this, a new London Transport Executive Centre of the SJAA was formed.

For continuity, all papers regarding the Metropolitan Railway Centre through its various iterations to closure are catalogued here. Papers relating to London Transport which are not specific to the Metropolitan Railway or any of its committee members will be catalogued under London Transport.
