Ok , so im looking into buying a new transformer for my train because it runs slow and can only pull 4 cars right with 60 watts. So i call the local hobby shop and they have a transformer a lionel kw or something with 175watts and cost $225 right. I ask the question if buying the transformer with more watts will help my engine pull more cars, the guy says no, the engine will not pull any more cars then 4, but it might go a little faster. That dosen't make sense if it goes faster, dosen't it have more pulling power? So why spend $225 if its not going to make the train engine perform better. Then i will have to buy a transformer that makes no difference, then have to buy another engine that can pull more cars also. I wish i knew the answer to the question how my train would run with 100+watts if it would be worth the investment. To bad i can't rent a train transformer for just the day to test it out. Im beginning to think my hobby shop is pretty expensive if the cheapest engine is $195, and a transformer $225, my gosh by the time i buy accesories and box cars it would be over 1,000 crazy.
