Block signalling on the GN :
Phase 1:
A fellow railroader is the 'brains' to this, I'm just the minion.
He drew up where the signals should be.
When I switched from DC to DCC, I merged common blocks under one district. There are 8 districts. The blocks are labeled as B and, starting at 100, the first digit is the district and the last digit is the block, ie B 100, B 101, B 200, B 201, B 202, etc.
Signals are labeled as SW XX, starting at SW 01 through SW 23. The signals are located at the ends of all blocks. Some signals are double mast to indicate which direction to take at a turnout. Yard details are not illustrated.
The signaling system is suppose to detect current through the wire to activate the signal lights. The block wires will be used to detect the current.
The mainline is 400' long. With normal train length of 25-45 cars, the blocks and sidings are set up to handle these train lengths. The layout is strictly point to point with an interchange/staging yard at one end.
Got 20 and another 17 in transit. I will have to 'kit bash' for the double signals.
LED operated.
