Roman Schmidt comments "This shot was taken from the footbridge next to Wimbledon B signal-box and shows a Salisbury-Waterloo stopper approaching the station. The non-electrified loop line on the right ran from just beyond another footbridge in the far distance opposite Wimbledon C signal-box and served a small platform known as the milk platform, so called from pre-tanker days when milk churns were offloaded there, and can be seen bottom right.

Locomen apparently referred to the rarely used loop as 'Volunteer siding' from the early days of WW1, when volunteers who signed up would assemble on the platform ready for embarkation. Much later in the 1950s and early 1960s, the platform was used to unload imported Italian Lambretta motor scooters for the company's Wimbledon factory. As late as summer 1962 I recall seeing Schools 30925 arrive at the platform on such a duty and the following spring 1963, the extraordinary sight of WC 34030 stationary on the loop with the weekday afternoon Clapham Junction-West of England milk train empties.

The large corrugated building on the left also has its roots in WW1, and is a remarkable survivor. First erected on the beach in 1918 at Newhaven for the Royal Naval Air Service, it was used to house and repair seaplanes patrolling the Channel. In 1921 the building was sold and acquired by the L&SWR, and in 1923 at the time of the Grouping the newly formed Southern Railway re-erected it at the top end of Wimbledon West goods yard for use in their suburban electrification scheme of the 1920s. In 2012 it was given listed status.

In recent years consideration has been given to reinstating the loop as an electrified line to increase line capacity and the old building and former goods yard may yet see a temporary return to railway use if the latter becomes the main tunnel portal construction site at the south west end of the proposed Crossrail 2."
