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.
