Mike Boos pointed out that it looks like there's going to be a very wide MUT on the sides through here.
Crossover at Cameron Heights, on Charles.
The crossover is set up as trailing-point, meaning if a train wants to get on the "other" track, it has to pass the crossover, then reverse through it. This makes it safer, because in the event of a switch failure you'll never have a condition that could lead to a head-on crash.
With that in mind, the lamps at the left are for a train on the left tracks, about to move through the first switch ("facing point"). "|" means the switch is set straight, "/" means it's set to the right, and "-" means it's not safe to proceed (either because the switch is moving, or there's a fault).
The lamps on the right are simply indicate that the trailing-point switch it is about to move through is either clear ("|") or not clear/set the other way ("-").
Looking down Charles, toward Stirling.
Finished OCS on Borden!
