===1935–1940: Introduction of trolleybuses===
The [[London Passenger Transport Board]] was formed in 1933, taking over the London County Council trams. It was decided soon after to replace all [[trams in London]] by "more modern vehicles". The abandonment programme began in 1935 with trams in South-West, West, North-West, North and East London mostly being replaced by [[Trolleybuses in London|trolleybuses]]. The replacement programme proceeded swiftly until 1940, when the last of the pre-war series of conversions occurred, leaving only the South London trams and the subway routes 31, 33 and 35, the only North London tram routes to survive the war.<ref>{{cite web|url=http://tundria.com/trams/GBR/London-1940.shtml|title=London 1940|first=Gabor|last=Sandi|website=tundria.com}}</ref>

Prototype Kingsway trolleybus no. 1379, with exits on both sides with folding doors, was constructed for feasibility tests through the subway, but these were unsuccessful as trolleybuses would have had to run on battery power through the subway, headroom restrictions making it impossible to use overhead current collection. The vehicle was retained and ran in normal service alongside conventional trolleybuses.

====Waterloo Bridge rebuilding====

In 1937, the rebuilding of Waterloo Bridge required the diversion of the side entrance to the tramway to a new position centrally underneath the bridge, which opened on 21 November of that year. There were metal doors covering this entrance until 2007, when construction began on the London Buddha Bar, which opened in autumn 2008.
