and the service being used by 36 million passengers a year. The tramcar route to Bradley was to have been converted, but motor buses replaced the trams instead. In 1930 a circular service to Whitmore Reans began operating, which included a branch specifically to serve the Courtauld's textile works. A new departure was the route from Willenhall to Fighting Cocks, which did not involve the trolleybuses starting at the town centre. In late 1931, through working with the Walsall system began, when the Willenhall line was extended, enabling Walsall trolleybuses to reach Wolverhampton and Wolverhampton trolleybuses to reach Walsall. The joint working began on 16 November 1931, after a low bridge on the Willenhall route was modified to allow the running of double-deck vehicles. The Corporation were now opening routes well beyond the confines of the old tramway system. Trolleybuses ran to Bushbury Hill from 30 November 1931, and to a number of developing residential areas subsequently. The Amos Lane and Pear Tree routes opened on 21 March 1932, and on 10 April 1933 a service began serving Brickkiln Street, Jeffcock Road and Bradmore. The Penn Fields route had been extended to Penn on 10 October 1932, and a second route to Penn opened on 8 April 1935. The Wednesfield route was extended to Lichfield Road on 10 February 1934, and trolleybuses replaced motor buses on Oxbarn Avenue the following day. By 1936 there were 90 double-deck and 18 single-deck vehicles in operation. Single-deck vehicles were used on the Fordhouses route until 1938, but those on the Wednesfield route continued until 1943, when the roadway beneath a railway bridge was lowered, allowing double-deck vehicles to be used throughout. The single-deck vehicles were then sold. The situation during and immediately after the Second World War appears a little confused. Joyce et al. state that 38 extra vehicles were obtained to meet wartime traffic levels. Lockwood states that wartime needs were met by borrowing 12 Sunbeams from Bournemouth, and the purchase of 38 Sunbeams with utility bodywork between 1943 and 1946. The fleet list published in Joyce et al. shows 18 Sunbeams entering service between 1940 and 1942, and 38 Sunbeams with utility bodywork arriving between 1943 and 1946, so the earlier reference to 38 vehicles appears to cover the utility vehicles, some of which did not enter service until the war was over. Between the end of the war and 1950,
