Himself was thinking ahead and anticipating worst-case scenarios when he designed Minffordd, and he was careful to allow access in the event of a major failure or track relaying being required.
At the moment he's investigating a curious fault with the route-setting function.
At each end of the Cambrian yard control panel is a rotary switch where the operator selects which road they require, press a single button, and a matrix of diodes and relays set the points accordingly.
During the Glasgow show we noticed when you had Road 1 selected, and wanted to change to Road 4 the 'king point' - where roads 1-2 and 3-4 d split - would not move.
However, if you select Road 3 instead, the point will switch as it should, and you can then make a follow-up request for Road 4.
This explains a number of strange head-on collisions in the fiddle yard during the show which baffled the operators who were quite sure they had changed the points, and the LED indictor on the panel backed them up!
So one of the items on the snagging list to be tackled before the next appearance in Porthmadog is to find out what is causing this.
Removing this 'secret panel' makes it much easier to see what's going on under there and whether the point is being switched when it should be.
