N Gauge LMR Twin Sisters Loco Scratch Aid

This is an N Gauge model of the Liverpool & Manchester Railway locomotive ‘Twin Sisters’, an early and very unusual design that helped build this iconic railway.  Combined with the N Gauge Twin Sisters Tenders and Motion Pack (separately available), this scratch aid enables an unpowered free-rolling model engine.  Coupled to the motorised Liverpool and Manchester Railway coach or motorised flatbed (each separately available, plus free-rolling coaches and trucks), a fully working 'Era 1' N Gauge train can be created.

As the prototype was wildly larger than the subsequent loading gauge (!), alternate funnels are provided enabling scale or reduced-height options.

Necessary to Complete:
N Gauge LMR Twin Sisters Tenders Scratch Aid

(NB small strips of styrene will hold the driving wheels in place)
