If you are a fan of 2 rail operation you can thank Elliot Donnelly of Scale Craft ...who brought out his OO line in 1937 ( yes one year before Lionel) all in 2 rail ...proving 2 rail operation was practical ..for smaller gauges ... which meant it would work for larger gauges also ...
1939 Scale Craft introduces it's largest largest engine .the Chicago and Northwestern Class H Northern ...( these engines were huge ..and actually did a pretty good job of hiding the motor in the fire box ...unlike most of the other Scale Craft OO engines ) . Post war Donnelly had bigger fish to fry (making real $$ with printing ) so choo choo's took a back seat ..with a few extra hic ups .. but around 1950 the Northern was re- introduced ......to a ever shrinking OO gauge market ... this is a post war Class H ...with 12 volt motor ..pulling Scale Craft cars ...
