One more set of passenger cars PM'ed.
The NP were, even, worse than the ACL passenger cars! It took about 3 hours to clean the 14 cars and test run 850' on the mainline. Interesting: the observation car with the LED lights (for signaling purposes and train tracking) didn't have much gunk on the wheels; I would have assumed the electric current would attract dirt and not vise versa; on the 'other hand', checking the engines, there is no gunk on the drivers!
Had one derail but, after backing up and running over the same section, all was good plus the car's trucks checked out OK.
