I found a Old Lionel train set up in my new home The Engine 2-4-2 #1684 With a sound tender, and three cars as well. Tanker, S.U.N.X. #1680 with a built date of 5-29… Box Car Babt Ruth #1679 with a built date of 4-31-39…a Caboose #1682. Is their any value to these trains or should I put them in a yard sell? [D)]
