This Lionel Prewar O Gauge Train 636W 2-637s 638 City of Denver is a must-have for any toy train collector. It features a pressed steel replica of the Union Pacific Railroad corporate roadname with a wheel configuration of strwam liner and a scale of standard scale. The train is made of tin/cast toy material and is in C-6 Very Good grade.This vintage electric locomotive, manufactured in the United States in 1936-1939, is a great addition to any model railroad and train enthusiast's collection.The transformer should  have the power cord rewired but all in all don't miss out on this opportunity to own a piece of history.This is a complete set W/Track,transformer,track locks,and power clips of 4.I have no idea if it runs but it is very clean inside and out and all pieces are there.All the badging is near perfect.A very good piece to repaint or use as a original played with piece.It is a flat 1 price shipping because of the weight if its less it will be refunded.I think this is a great very old original piece even though it has nicks it is complete with no breakage.Make a fair and honest offer you never know.Thanks for looking
