Hi all, I just got a Hornby Mallard. (Motor in engine, not tender). I'm not sure of it's Hornby R**** number. It keeps stalling over one point. I have 7 points on my layout and it just plays up one this one. Its fine at speed, but anything slower than half it stalls. All my other locos run fine over it. I've cleaned it thoroughly. She runs super smooth otherwise. Any suggestions ? It's standard Hornby track with the plastic, isolated frogs. I think that might be the issue right there. Cheers Kev.
