Hi I hope someone can help out on a problem that has be baffled.
My son has a Hornby layout consisting of a the three standard radii The outer track is connected to the middle via R8074/5 Points The middle track is connected to the Inner via R8072/3 Points Each Track has it's own R965 Controller,R602 Clip and C912 Transformer. The layout is pinned to a MDF Board overlayed with a sheet of Granite Ballast The Locomotives are Hornby R2326 060 Class J94 Hornby R2261 Flying Scotsman Bachman Class 221 5 Car Voyager with tilting action.
The Problem is locomotives fade out after different running times on the Outer and Middle Tracks
J94 Outer-20mins approx - Fade out Middle-20mins approx - Fade out Inner-OK
Flying Scotsman Outer-20mins approx - Fade out Middle-20mins approx - Fade out Inner-OK The Scotsman also seems to be jerky on the outer straights on slow running.
Voyager Outer-3/4Circuit - Fade out Middle-1 Circuit - Fade out Inner-OK
Voltmeter shows a steady decline, this returns when the locomotive is removed, attempting to restart in this period gives a short burst before it fades out again.
We first noticed the fade which I suspect has always been there when we attached a set of R406 Light Signals to the outer transformer. This gave us an obvious visual indicator of the fade out, now removed as part of troubleshoot.
I am now baffled and on the verge of a complete rebuild, before doing so if anybody has got any ideas to try out it would be very much appreciated by a clueless Dad starting to dread Christams Day.
