From the developer:
Westbury has always been an interesting railway centre, located at the junction of the ex-Great Western main line from Paddington to the West Country, the Trowbridge line (towards Bristol and South Wales) and the Salisbury line (for Portsmouth, Brighton, etc). The Westbury track layout was remodelled in 1984, when the power box took control.
Passenger services comprise HST, locomotive-hauled and multiple-unit trains.
