I also can't seem to get the whistle to work, but I guess I don't know how that function works. I also can't speak to the condition or completeness of the tracks. I have seen that many are missing pins or have makeshift pins in them. Coal car 2452X (damaged and cracked on side). 29 pieces of curved track.
2 pieces of small curve track. 26 pieces of straight track. 2 signal lights and battery case (missing case cover, functionality unknown). Transformer multi control type 1042.
