[quote]QUOTE: Originally posted by kevnbety I have heard that metal wheels have less "rolling resistance", therefore making it easier for your locomotives to pull a train than the plastic wheels that come on most rail cars. Is this true? If so, how much does it REALLY help? Thanks for replys, Kevin [/quote] This is because harder things have less rolling resistance. For example. Get on a hill and roll a marble down. Then roll a cotton ball down. Not a very good example, but you get the picture. Plastic wheels make a lot of the junk that builds up on your rails as well. Its sort of like mopping the floor and then jumping around with muddy shoes. (me and my examples!!![:D][:)][8D]). With metal wheels you can pull longer trains and your track stays cleaner. Plus they make that cool clickity-clack noise.
