On the 21/02/2017 I managed to film a Rail Operations Group (ROG) Class 37 dragging 2x GWR Class 387 EMUs pass through Maidenhead on a transfer move from Reading Depot to West Ealing sidings. The reason why the Class 387s have to be loco hauled to and from Reading Depot is because the electrification on the GW main line isn't complete between Reading and Maidenhead at the time of filming this clip.
