Thanks for all the replies.  Will try adding weights to tender. The little plate appears to lock the wires in place, it can only go in one way since the little semi circular hole goes around the draw bar pin. Mine does not appear to be tightened right down, space underneath. Will take off and check that the wires are not doubled up under it.
Also had some problems with front bogie, tried weights didn't fix, will lengthen spring, see how that goes.
Won't be able to check for a while, have just ripped up all my tracks to put in a new layout, wasn't happy with my first one.
Used software called "SCARM" (Simple Computer Aided Railway Modeller)to design layout. Very good, particularly as its free.

The Alco 2-6-0 Mogul that I bought a few months ago will not stay on the rails. It keeps running off, particularly on bends and points.
There seems to be a problem with the front bogie on the tender. When turned it catches on a little plate that is screwed to the u/side near the electric wires that go from tender to loco. Have tightened screws to no avail. The tender then derails pushing loco off. If I loosen bogie just makes problem worse.
Has anyone struck this problem.

Hi All. I live in Australia and have just restarted the hobby after a 35 year absence.  Have decided to go Old American circa <1900. in HO
I have bought a Bachmann "HO" American 4-4-0 & Tender Item No. 51124. Still in box. Love the look of these locos.
Am in the process of designing a layout to suit my requirements to run 2 locos and a shunter.
Have been reading all about DCC  vers DC and have come to conclusion that DCC appears to be the way to go.
Anyway is it possible to make my loco DCC compatible. Is there an aftermarket kit available that is fairly simple to use.
If so, how much and where do I get it. PS. I am not too good with electronics, normal electrics OK.

Thanks Kenmac
