Hi all this is my first post so just a brief intro. I have been waiting 40 years to get into model rail and have made a start recently.
Today I fitted a decoder to a DCC ready Hornby Fowler 2-6-4T. The whole job took twenty minutes and no problems encountered.
Loco runs well although the track could use a clean.
My main problem is that the loco will derail constantly on points when travelling in reverse. I think the driving wheels may be too close together as the leading pair (in the reverse direction) seem to climb up onto the plastic guide rail on the turnouts.
The wheels that seem to be at fault are closer together than the others but I'm not sure what the correct dimension is and if it's measured back to back or from front of flange to front of flange.
Is it a simple matter of gently levering the wheels further apart whilst in place on the loco or is it a dismantling job. I have a set of vernier calipers so I could get the distances quite accurate.
Thanks in advance for your help
PS Track is Peco settrack with some flex track - points are Peco setrack.
