Hi Tolis,

My guess is that the loc is not getting power in the curve.

Do the headlights stay on when it stalls?

If not, I would check and clean the wheels and pick-up shoe, as well as the track.

A remote possibility could be a loose wire or contact inside the locomotive. Initiating the turn would twist it just enough to loose contact.

I would clean wheels and tracks first, it's easier <img src=icon_smile_approve.gif border=0 align=middle>
