Slough–Windsor & Eton line

A 20-minute service interval in each direction is operated by Great Western Railway using the dedicated bay platform 1 at Slough.

Most service trains accessed Slough station by the eastern chord, which remains in use.

All land west of the eastern chord was sold for housing, and there is little evidence of the junction at the site now although aerial photographs show the curving line of the western tracks.

The only intermediate stop on the branch line was Chalvey Halt,[5][6] 47 chains (945 m) south of Bath Road Junction.

A note in the GW Engineer's Department minutes of 19 October 1930, records that the materials from Chalvey Halt had been used to build Cashes Green Halt on the Gloucester to Swindon "Golden Valley Line", between Stroud and Stonehouse.
