They also appear to have a white "S" painted on the back shade.
Correction: "C", not "S".

I'm not familiar with the territory, but my guess is that the signal department is in the process of converting from fixed automatic block signals (between interlockings) to cab signals WITHOUT block signals.
The "C" probably means "clear to next interlocking". It's used in other areas already.
This would be displayed for a train that had suffered a cab signal
failure, which would otherwise have to run at restricted speed (since
the engineer has no way to ascertain the condition of the block ahead).
In order for the "C" to be displayed, there has to be an "absolute
block" (no other trains) from the affected train to the next
interlocking ahead.
The C means (the wording may vary from one railroad to another):
"Trains and engines without operative cab signals may proceed on fixed signal indication, not exceeding 79mph, and approach next interlocking signal prepared to stop"
At the next interlocking, the train must receive another "C" (along with fixed signal indication) in order to proceed further.
It's really only for when the cab signals on a train have failed.
