I still have my '50s American Flyer *Work Train*. It came with a 0-4-0 (IIRC) and 4 cars: Combination baggage/coach, search lit car, crane car, and work caboose. I got an E-(??) Union Pacific diesel engine later, and I have one switch , the transformer and a whistle *box*. Everything works now, but it could all use a good cleaning! (I set it up at Christmas a few years ago, and it *smoked* after all these years!)
