This part a large collection of tomy train sets that my son had late 80s early 90s. This a collection of trains, have tested them all of them seem to be working ok,  Some a little slower than I remember! Cleaned around the wheels and replace tyres that had perished some have the odd marks on them. The leaver on blue train has been snapped in half and oh number 78 prefers to go backwards ! nice pieces to add to set, please see photos.
