From 'Fe Plate Main' to 'Fe Plate'
I had added a 'FEP Rt0' which is a station closer to main and it cannot even get there.
This is a save called 'NoPath' at the time I finally gave up trying to coax it to work....

I had another stop along the west branch just after the FEP Rt0 called FEP Rt1 but that didn't help... I even tried to add a stop like just after the loop at main it it couldn't even get there; I guess I had cleaned up those extras before this point though.
This is an earlier version of the loop I had... just before this I didn't have the south-east path from the topmost circle route, and it was having problems, so I added a direct path from that loop back to the loop before the main; it didn't help; so as above, I removed the second loop entirely and just brought it back.
The other tain on the east-most stop has no problems getting in and out - but it's main route goes to the south from the T junction...
Closer view of more simplied path.. (same as NoPath save point...)
