I installed it in a bachmann 4-6-0 Steam Locomotive. It work for two days and then it stop working, no sound, movement. Follow instructions for troubleshooting but still doesnt work.  I think it's a lot of money invested for items with poor performance plus tax( 11.5%), shipping & handling($15 to $20). There is no fun!
