Hi just wondering what the smallest trolley, engine, eggliner, or anything g scale  that is made that has a motor unit in it is?

Hi Chuck, thanks for your reply. It was something simple (dumb); I did not connect the plugs of my airwire connector correctly. It threw me off that there was sound but no movement. Good lesson to make me check that!

Hi just ran my Silverado yesterday and it was running great. Today the engine is acting like the brakes are on, not moving? Any suggestions?

Thanks Hunt!

Hi, just purchased this set while my layout is now being built. I put the engine on the piece of track and noticed all the wheels are touching except the middle wheels. Anyone else notice this? Still runs okay? Thanks!
