Megapolis: Portland Train Bug

Lately, I have been using all of my assets to finish up my train depot.  I like to upgrade all of them evenly to maximize my coin rate while minimizing "unused" building requirements. As of now, I have 2 Portland and 5 New Jersey Trains and I only need to upgrade my Maintenance Shop to lvl 4 before I can start upgrading to Amtrak.

I just upgraded my B Train to Portland today.  Then, one of my neighbors sent me Anchor Bolts which would normally go to NJ Train C.  I go to apply them and I see that I can apply them to Train B (Portland) but not train A (Portland).

This isn't just a visual bug.  I accidentally applied 1 Channel to Portland Train B.
