Smartframe: An accurate, reliable and simple method for producing rolling stock. A difficult and tedious task encountered when crafting rolling stock is the preparation, cutting out and alignment of the windows, droplights, panels and beading. This is especially difficult in smaller scales. Smartframe is our solution. Smartframe reduces the time, complication and labour associated with the construction of rolling stock using accurate lasercut layers which are conveniently assembled without specialist knowledge to give the same quality, or better, as traditional methods using plastic or etched components.
