So, I can't find the post, so here's a brief description with the diagrams I had made up to go with it.
Here's the layout in that area:
Here's the path freight takes (note that freight must always cross over to the SB LRT tracks - because those are the only ones with gauntlet tracks installed):
Here's the path LRV's take, in normal operation:
Look on the left; you can see two half-crossovers. Freight uses the one on the far left, LRV's use the one on the right, closer to the intersection. They are different types - freight can only use the one at the far left (further North). LRV's can use both, from a wheel-interface standpoint, but in normal operation (beyond testing) they'll only ever use the one at the right - which is the only one fitted with permanent contact wire. The temporary contact wire strung above the freight crossover allows LRVs to turn back without blocking the intersection.
Hope that makes sense!
