Lionel Hooker Tankcar - Niagara Falls, New York
This model is Lionel 6-19636 which was issued in 1991. This is a nicely detailed model that includes separately applied grabs, DOT HAZMAT placards and sprung trucks. The car is marked "caustic soda" or sodium hydroxide. The appropriate DOT placard would be Class 8 "Corrosive materials".
