Suitable for the Bachmann 5700 and 9600 series and, with a small amount of fettling, the Mainline model. The kit includes motion bracket, slidebars, crossheads, connecting rods, dummy valve gear and fully-removable brakegear (two types).
 
This chassis can be built in 'OO', EM or P4 with either rigid, or with twin-beam compensation. There's plenty of room for a good sized motor which drives a double-reduction gearbox to deliver superb performance - the motor sits snugly inside the boiler with the gearbox concealed inside the ashpan leaving the cab completely clear.
