Ok guys I googled for a page to help me with my train set and this seems to be the best so here is my problem When I was 4 years old (1991) my grandfather bought me a train set for my birthday (he was a modle train lover) and the set he bought me is a Lionel, Santa Fe Special Set. In case you aren't familiar with this set the locomotive blows steam and has a front light and it came with a few cars (random industial cars, coal car.) and of course track. Well he passed away about a year ago now and I found this set in my closet at his home. It has been dormant for roughly 4years now and I set it up hoping to see it in action again but to my dismay nothing happened. I hooked it up correctly the engine is on, the 3 pronged track clamp where the power goes to the tracks was on correctly. basically no technical problems I could see ,the locomotive seems ok because the passenger car we purchsed a few years back for it didnt light up. so either both the locomotive and the car are messed up or its a power track problem. any suggestions on how to fix it? a friend who has trains said I had to clean it? how do I do this? Also if oyu are familiar with this set could you confirm it is HO scale. I am not sure if it is, I am not to familiar with classifications.
