I just purchased a 2014 MTH 4-8-4 Imperial locomotive. Some of the soft keys do not work. 1. SSU EXT start-up, 2. STW Train wreck, That key gives the sound but the Engines does not stop. I haven't gone through all the keys so there could be more. Another item is the crew talk is very limited.
I was told at the Hobby Shop, "These engines do not have batteries".
