Forgotten Branch...I can help you out with those numbers.
The 4 car passenger set numbers are 11-40072
The loco I purchased was the Traditional version # 11-2031-0
The proto-sound 3 version number would be 11-2031-1
Chris, great video's! Love the freight cars behind the Presidential loco...
Long as I'm posting....found something else kind of interesting awhile back...neat Flyer brochure...
