Class 800 train ride - London Paddington to Slough

On board a Great Western Railway service class 800 hybrid train from London Paddington to Slough on Saturday 26th September 2020. We travel through the west London suburbs where snippets of the London Underground Hammersmith and City line can be seen departing Paddington and also the Central and District lines as we pass through Ealing Broadway. The class 800 is known as a 'hybrid' or 'bi-mode' in that it runs on electric power but uses diesel generators on non electrified routes.
