Class 143

The Class 143 was built at the same time as the Class 142 and is also a railbus design marrying a bus or coach type body (built by coach builder Walter Alexander) to a chassis derived from a freight vehicle. The Class 143 perhaps look a bit more like a train however compared to the 142, the body of which retained more aspects of its Leyland National bus heritage.

Originally the 143s worked for British Rail's Provincial Sector and the Tyne & Wear PTE. In the privatised era they are operated by First Great Western (GWR) and Arriva Trains Wales. Like the 142s their original transmission has been replaced with a Voith hydraulic one. As with the other railbus designs the 143s are probably in their final years now with withdrawal planned for the end of the decade.
