Model railroads.

Well yesterday was a big hit on the credit card. lol I bought 2 Rapido Diesel locomotives complete with sound, and an MRC digital controller with one reverse loop module. Plus all my Atlas Code 100 track for the layout. This is not as costly as the car hobby, but it's not going to be cheap by any means. This is going to be at least a 5 year project to get this layout completed.
