File:Marx 400 features- how many versions?

Description
Marx 400 features- how many versions? Review of the Marx 400 locomotive and it’s functions. Also comparisons made with the Marx 666, Marx 898 and Marx 490 to determine how many versions of the 400 there may be. Then we test it’s functionality around an O scale layout. Leave a comment if you want to see a Marx 400 makeover. If you like Marx toy trains see my other makeover videos on Marx 1666, 490 and more.
