I recently went on a trip to a train store in Ontario Canada called Lark Spur Line. I wanted to have a look through a recently acquired collection of brass and die-cast locomotives.
Looking through the boxes did not disappoint as there were many fully decorated engines, must even featuring DCC and sound.
I also had a look through the shops consignment section for cheaper locos being sold at a discount. I ended up finding a vintage Canadian National switcher and two customized FA1 units which appear to have an early form of DCC.
Huge thanks to the guys at Lark Spur Line for their help in the search for vintage locomotives
