USA Trains , G -Scale , if I remember correctly your company was the very first to produce a Speedway Express Ltd piggyback car, It was way back I saw this in a train store in North Hatley Quebec I believe I was very impresed , but as it was G Scale it was way out of my league , beside at that time I think I had given my Lionel set to a nephew .. I no for a fact I was ineed very surprised to see that livery , it sure made my day .
