Lindsay2 is a railcar, railmotor, doodlebug, or what ever you call it in your area of the world.
Designed to fit on a HO scale MRC F7 chassis, items like couplers, end plates/pilots and detail items need to be added by the builder.
Lindsay2 is an adaptation of Lindsay1 (not for sale), a model that was a requested upscalling and modification of the HOn30
Megan 1.
There is ample space between the passenger section and the freight doors to fit vents, grills and radiators as the modeller sees fit.
The model is optimized for printing in WSF (now know as Natural Versatile Plastic), and was designed for strength over reducing cost. It is not your typical flimsy thin walled model, however this has increased the cost over that of similar sized models.
