Engine stops at switch and starts up

 Mike, are you running the engine using DCS ?  It sounds like the engine is stalling and then coasting to a stop and restarting in conventional mode. Try pressing start up on the Remote and see if you gain control of it again without powering the layout down.

 A few things can cause the engine to stall. What type of switch and what type of engine ?   It could be a roller spacing issue. Often times you may need a relay to change the polarity of an isolated rail.  I’ve found especially on diesels with multiple traction tires. The wheels don’t have enough good contact with the outside rails and will cause stalling.

Hi Dave, I am running DCS, on MTH ScaleTrax, with MTH Switches. The engine I am running is a MTH PS2 PH40 diesel without traction tires.

When it starts up I shut it down with the DCS remote and restart it, but it wont move if I don't go threw all of the PA's.

Hello Mike, I had a similar problem with my switches in my Lionel command layout. The engine would stop half way through the switch. If I manually eased the engine through the switch to the other side, the lights would come back on, and the engine would start up and operate normally again. Then I remembered reading that some switches don't carry the power through the switch...and some do. My Ross switches, as manufactured, don't.  I believe Gargraves, for example, do. I'm not familiar with MTH.

My only other thought would be possibly a short somewhere between rails in the switch ...or like Dave mentioned, loss of contact with wheels or rollers as the engine passes through the switch.

Just a thought!

Mike try cleaning the wheels,rollers, and switch track and the parts of the rail that move and make contact with the side of the rail. I'm surprised your having this issue with a PS2, sounds like a PS3 44 tonnner problem..

Hi guys, I figured it out. The small section before the frog was not getting power. I soldered it to the next piece of track. Now it works fine!
