It is a report of my solution to the problem using a Peco_SL-E194.
Picture the crossing with the long axis horizontal .
Working from left to right I will refer to the four wires fitted to the crossing as:
A & B [ left pair ] and X & Y [ right pair ] . Think battleship gun turrets .
What I did:
1. Fit insulated fishplates to the End_Frogs ; a total of four .
2. Fit conducting fishplates to the Frog_Arms ; a total of four .
3. Connect B and X to the Track Bus . This means that that the four crossing rails [ the short rails
immediately outside the diamond in the middle ] will be permanently live .
4. Connect A and Y to the two Track Outputs of the RLM, i.e. Power Out .
5. Connect the Track Bus to the two Track Inputs of the RLM, i.e. Power In .
6. I am not sure if it matters which way round either of these pairs are installed as long
as the inputs and outputs are not mixed .
However it may be necessary to pair the End_Frog wire with its associated Frog_Arm .
Note:
Only one RLM is required so this is probably the cheapest solution to the problem .
