I have to much to list
My late father and I collected Lionel the Collection goes back to the 1930's to present. Almost one of every item Lionel offered, plus some versions of the items, example I have at least 3 of the Milw Rd loco's each of them diffrent. At Trainfest in Milwaukee I have been taking a 1938 Lionel OO layout. I would recomend getting a Lionel repair manual, Kalmbach produces a basic little blue book of re prints of lionel service manuals of pouplar postwar items. Another company offers a CD of all the service documents. Repair parts may be purchased from Rustys trains in Two Rivers wisconsin, or at Somerfields in Butler. I have also ordered parts from Olsens in Ohio
If you decide to Collect toy trains, I would recomend getting a price guide from Kalmbach so you have an idea of values. You also may want to consider joing the Train Collectors Association and the Lionel Collectors Club of America.
