[3][page needed] In July 1910 a new shed was opened at St Philip's Marsh alongside a line which allowed through trains to avoid going through Bristol Temple Meads station.

This new shed was mainly allocated freight locomotives including 0-6-0 Pannier Tanks which plied their trade mainly in either Bristol Docks or at Avonmouth.

Bath Road, which could not expand due to the proximity of the River Avon, now serviced mostly passenger train locomotives[3] St Philip's Marsh shed was constructed to Churchward's standard design with two-turntables and a north light roof.

There was a standard pattern twin-ramp coaling stage, but the repair shop was only a small two-road building, due to the closeness of Bristol (Bath Road).

[7] A site north of the Avoiding Line was used for the construction of a new maintenance shed 250 m (800 ft) west of Marsh Junction depot.
