Eight four-car Class 387/1s will enter traffic with Great Western Railway from September 5.
They will be used between London Paddington and Hayes & Harlington initially before operating further west as Network Rail electrifies the GWML.
On August 12, JACK BOSKETT visited Derby Litchurch Lane, where the '387/1s' are being constructed, to view their progress.
