I am continuing the debugging of the track. Following the test of the turnouts from the Up main line into the engine shed with the 3F - shown in the previous videos - testing with my Hornby Black 5 showed that all was not well with the double slip. The Black 5 had an annoying habit of mounting the crossing V at the coaler end of the slip. This double slip was the first 'complicated' piece of track I ever built and has only recently come into full operational use. If you look closely at the slip you will see evidence of a partial rebuild of the slip - new solder - as I re -aligned the far crossing 'V', wing rails, closure rails etc at that end of the slip. The Black 5 now runs through without falling off - result :) .
