The Pacerailer was a prototype railbus, a vehicle consisting of a bus-style body on a four-wheeled railway-vehicle chassis, built by 's (SRC) in the 1960s. Following the closure of Droxford station, on the Meon Valley Railway in Hampshire, both it and the track south to Wickham station were leased by SRC, who used the line to demonstrate the Pacerailer to potential buyers. A section of the line was rebuilt with a 1:10 incline to demonstrate the vehicle's abilities on steep gradients. A similar concept, the Pacer, was successfully developed by British Rail in the 1980s.
