Just ran Service Q261 using C40-8W as lead loco. Noticed that when heading west, distance to objective (Mance) stopped counting down at 5.1 mi. When I reached the marker it still read 5.1 mi. Then for next objective (Salisbury), it froze at 3.7 mi all the way to the marker. For next objective (Rockwood Main No1), it froze at 10 mi, then jumped to 2.1 mi for the last bit. I've noticed this behaviour recently before. It seems to only happen randomly and within NW part of SPG route. Good news is that banking comms now works on C40-8W!
