EPW038700 ENGLAND (1932). Brent Junction and housing off the North Circular Road, Stonebridge, from the south-west, 1932. This image has been produced from a damaged negative.

I think the N C Rd may have been opened in 1934. So this section although ready, carried no traffic.

Not to be too pedantic but the correct term is "hump" not ramp.

Opened in 1906 by the Metropilitan Electric Tramway [MET] company to serve their new tramway between Harlesden High Street and Stonebridge Park. To accommodate the trolleybuses when they replaced the trams from 5th july 1936 the depot was enlarged and rebuilt for through running. London Transport had a trolleybus driver training school here with a wired circuit around the perimeter of the depot, and a simulator in the classroom. Stonebridge was one of the depots which operated Class C2 buses which were distinguished by the 'spats' over the rear wheels. On 2nd January 1962 as part of stage 13 of the conversion plan Stonebridge went over to diesel buses, so the tram shed which became a trolleybus depot was now a bus garage.
