Intermittent Engine Stop

It sounds like signal issues, as when a TMCC locomotive loses signal, it will stop.

Does it stop at the same places on the layout?  If you hold your hand over it as it runs through a problem spot, does it continue without stopping?

I would also check the engine grounds, especially the rear truck.

sounds like it might be an antenna problem,

Take a look at this thread and see what you think,

It is interesting it responds to commands immediately.  I would think a reception issue would cause the engine to be non responsive in that area.  G

Maybe it coasts past the problem area.  Hard to say without further diagnostics.

Gents:  thanks to all of you for your suggestions - I will have to wait a while to try to leverage these ideas (company tonight and then going out of town).  Several things in response to comments:

1)  the place that it typically stops is below a bridge so that does lend credence to the points raised by many of you.  Unfortunately, it is in a location (naturally) where putting my hand over the engine will be very difficult.  I will definitely try that before installing ground planes.

2.  I ran the engine very slowly prior to a stop (and then immediate restart) so I don't think it coasted past the bad spot although it is possible.

3.  I have had issues with TMCC control of engines in the past (not stopping, just general control, particularly whistle/bell control) - the engines would be unresponsive to the controller when far away (~ 20 feet) from the Cab1.  I seem to notice this most in the winter - hard to believe it is atmospherics but I guess anything is possible.

4.  I was intrigued by the comment about Legacy working better - I am thinking of upgrading to that controller - any other similar experience?

Again, thanks for your support; happy New Year!!
