noctilux2 Posted March 16, 2015 Share Posted March 16, 2015 Having great problems in successfully wiring this simple layout (please see diagram). Points are all electrofrog chosen as I intend to run only (very) short wheelbase locos. Power feed is shown by the red / black triangles and a double insulating break is shown. When the point to the inside siding (B) is thrown to the main line, all functions as it should including access to siding A and the run round loop. When however access to siding is needed & the point is thrown accordingly, a short occurs & power dies. Presumably I need a further insulating break & / or a power feed. But where. There is obviously a very simple answer for you experts out there, but this numpty is tearing his hair out ! All help for this gratefully received........cheque in the post !!

Kenton Posted March 16, 2015 Share Posted March 16, 2015 The isolating break is in the wrong place - remove it and instead place it across the loop. The simple rule of thumb is to supply the toe of all points and to isolate every facing rails (in this case the crossover points should be completely isolated from each other where they face. The break across the loop is on the lower line only as the rule says facing points should be isolated and you have a point at each end of the loop "facing" there is no need for an isolated section across the upper loop. Leave the feed where it is and you require no further feeds - unless you wish to create section breaks within A or B - for example to run a loco in and park it at the buffers (isolate it) and use anothe loco to pull the train off.

RMweb Premium Chimer Posted March 17, 2015 RMweb Premium Share Posted March 17, 2015 Exactly .... and the simplest way to do as Kenton recommends is just to stick IRJs on all four rails diverging from the point at the right hand end of the loop, two on the crossover and two on the inner loop line.

Suzie Posted March 17, 2015 Share Posted March 17, 2015 The breaks are not in the right place. You will need four insulated joiners:- This will be all that is required for DC. For DCC you will need a couple more insulated joiners and a couple more feeds. Link to post Share on other sites More sharing options...
