Had some spare time at work so put a small layout up. ( plus boss was interested in dcc, so I showed him)

It got me thinking though. Most shunting puzzles rely on having one loco and a few un coupling points. What about having 1 uncoupling point ( I know , i know, not very prototypical ) and many loco's. Something different perhaps.

On other fronts, pulling my hair out over a 4MT. I think I may have fried another decoder in it. First one we believe was due to pick ups shorting out on the metal plate of the tender, However after taking all the wheels off and straightening out the pick ups so they couldnt short, there is still a short circuit in the tender. So pulled off wheels again, Re- examined pick ups - I believe they are OK, so then started to trace wires. Found an exposed bit where the wire passes through the metal base of the tender. This is shorting out on the metal plate. Pulled wire through so insulation was touching and soldered rest of wire to brass pick up plates. OK, atempt two.... "short circuit still detected".... " FRUSTRATION" .... in anger sever wires from tender pick ups.... Put loco on track.... no short circuit detected.... decoder doesnt program normally..... decoder has a hum to it..... solution, get angry at Hornby's 4 pin connector which requires tender is plugged in during testing and sulk.... make cup of tea.... put loco away..... keep thinking.....

O well, We will see. Have a look at it in a new light later.
