Not hard to get to 45ft cable lengths. I have a remote section of the layout connected by an Atlas double track bridge, (installed across a doorway, when I run). From the power supply 8ft up the wall, 8ft down the wall, at the remote section. add 15 ft across the ceiling, may be 20, routed neatly. Add a minimum of 5ft at each end for termination. I've had no problem with either TMCC or DCS.
Remote section wiring. Black and white coiled wires are two track circuits. Brown multi conductor thermostat wire is switch and other control.
Control power end of wires.
Track circuits, control panel ends. 14 ga solid THHN wire.
