RMweb Gold TheSignalEngineer Posted January 1, 2015 RMweb Gold Share Posted January 1, 2015 Foiled by inclement weather today, so the Grandsons came over and we had a play in the workroom. We made up a shunting puzzle consisting of three trains in four sidings, two each side with back to back points in the centre. The sidings have 21" clear standage. The capacity can be seen from the pictures. The object was to get the three trains sorted with the engines finishing in the same positions as at the start. The starting position Left sidings Right sidings Finishing position Left train Right trains Our best effort was 23 moves. Any offers for a lower total.

RMweb Gold TheSignalEngineer Posted January 2, 2015 Author RMweb Gold Share Posted January 2, 2015 Just to clarify our rules, the start and finish positions they are Start Wagon 2-Loco 1 Loco 2-Parcels 2-Coach Wagon 3-Wagon 1 Loco 3-Parcels 1 Finish Wagon 3-Wagon 2-Wagon 1-Loco 1 Loco 2-Parcels 1-Parcels 2 Loco 3-Coach During shunting only one loco is allowed in any one siding at a time, i.e. the next move is always into the siding without a loco in it.

SM42 Posted January 3, 2015 Share Posted January 3, 2015 I really must not try to do this in my head. My heads hurts now. Going off to find some track Andfy Link to post Share on other sites More sharing options...
Boris Posted January 4, 2015 Share Posted January 4, 2015 If I were doing this in the real world I reckon about 14 moves would cover it, using the model railway rules I think 23 was my best as well without cheating, although things were complicated somewhat by doing this in Train Simulator rather than on a model railway layout.
