Fellow Railroaders, I am working on a modern CTC panel using an industrial PLC and a touch screen. As my logic has been progressing (doing it in ladder) I keep hitting the wall on how to establish and manage more than one routing through the CTC system at a time…
Time for a different approach. Does anyone have any electrical drawings to an actual CTC panel? I would love to drool over them and see how the real guys managed the relay logic of competing routes and back checking of controls points.
My CTC is filling a block of double track on of my control points is pretty busy with 3 cross overs and 2 branches.
Any Help is appreciated.
