No data yet, but probably only because its out of the range of receivers.

Ohh wait. I got two control hits on it.

Now using the old CR diagram.. we can fairly match the machine.

C11 and C12 are switch number one. Now, the mainline 1 pair is gone. But the 1A remains. And it would make sense the DS would leave this reverse. Not a lot of moves over the diamond. This was a weird 3 switch pair. But now its a single switch.
C13 and C14 are switch pair number 3 for the wye. Also this wye is reverse 95% of the time. So this fits.
C15 and C16 are the 5 pair.
C17 and C18 is the removed 7 switch for the elevator.
C21 and C22 is the 9 pair.

Now the signal bits for this is weird.... there are four signal bits, and four stop bits here. No pairs.

The weird thing is that despite the fact that two physical non conflicting routes are possible from the southbound bracket. They are all tied to the same signal bit. 6S 1 and 3 (2 being no longer possible).

Someone back in the day at CR cheaped out on this dude. And it looks like NS simply put the Conrail era machine on ATCS (Like they did at Belshaw)

Decoding this stuff is going to be a beeeotch. The coal plant at Wheatfield shut down, there is nothing south of the diamond but a single customer. So only the rare local will use most of the plant. There is a grain customer towards wheatfield...

The 9 switch is the only thing that ever moves...

There should be three separate individual signal/stop pairs based on the drawing - 4, 6, and 8. One would think that 2E and 2N would each have their own Clear bit with a shared Stop bit.

I suppose that one could program the 6 signals to both show Clear from a single bit if the routes didn't conflict. I suspect that neither signal would clear with the conflict.

Ohh I forgot to mention that 2E signal mid plant is gone. Of course you can never be sure that there is not some ghost "virtual" signal bit left over in the plant logic.

I made an edit to show what is gone.

Amazingly Google earth took their car around the place in 2013, So there is street view.

The medium speed southward heads on the 6S bracket no longer function since the Danvile Branch signal system is dead.

I can't but help believe there is an error in the diagram, and that bracket doesn't indeed have two signal bits for it. 6S, and perhaps 10S?

One would think that an error like that would have been caught at drawing check time or at least by the maintainers. It could be that they are indeed trying to do things on the cheap (software is free, as they say).

To me, if there were separate signals, they would have been 6 and 8, as the numbers are sequential on the drawing.

I agree, though, that trying to get moves through all of the routes would be a stroke of major luck, even if we could get a decent feed from the area.

I am going to need to catch the local.

I forget the symbol... But I -think- he comes down out of Chicago, but even if it comes from the west. They use the wye to turn the train. And the only way to the customer on the Danville stub is across the diamond from the north.

But that means mid day, week day. And some of those locals are only 3 times a week.

Let me check with a potential source for the schedules in the area

The coal may be still running for a bit. I may have miss remembered and thought it was shut down all ready.

I take it that there is now some CTC on this line? I remember that Conrail ran it under DCS rules.
Thanks!

The north south line is CTC. (261 rules)

The line west from Schneider is DCS with the exception of CP MJ at Momence IL

Speaking of Momence IL (CP MJ) NS on it's "Doctor Evil kick" has installed a relay at CP-MJ

I say doctor evil kick, because NS is obsessed right now with controlling and seeing everything they can.
They rested control of the #2 switch at CP MJ from the UP since it is only on their side.

NS has put relay displays in some darn odd places. And this might be the craziest.
