Brings back memories.
My introduction to model railways was the 160 foot circuit in the attic of our stable, on Senior’s 1930s tinplate layout. I was about 11.
Big clockwork engines rattling round a barn with un-insulated track on wooden boards, and clattering coaches clicketty-clacking behind them….. to do one full circuit, you’d wind the loco fully, and it would just about coast to a halt at the right spot. Heavy trains, as in real life, had to be double-headed. The best option was an old 0.4.0 tender loco which was an absolute flying machine and could haul pretty much anything you put behind it….
