Kit Features

  • Etched brass fold-up construction.

  • Steel ‘guitar wire’ springing.

  • Primary and Secondary springing.

  • Primary springing by two independent spring beams on each side of each bogie to mimic the sprung equalization beams of the prototype.

  • Secure fit to locomotive chassis block, using an etched brass pivot frame.

  • Uses original A1A drive units, with straightforward modifications.

  • The centre, undriven axles are securely located and weighted.

  • The original cosmetic bogie sideframes are re-used, suitable fixing surfaces being provided.

  • Secondary spring hanger and seat details are included on the bogie bolster. Cosmetic secondary springs can be removed from the sideframes and fixed to the bolsters for added depth of detail.

  • Optional etched brake shoe, hanger and lower pull rod components can be fitted to replace the original representations which are moulded flush with the outside of the bogie rather than being aligned with the wheels.
