PC Platform Stop Markers (6 Cars, 8 Cars, 10 Cars) Are Misplaced Or Missing

On the platforms on Boston Sprinter the platform stop markers are poor.

At Route 128 in the up direction (heading towards Boston) the markers are well after the station. On the station after that one is on the platform, one is on the pedestrian ramp and 10 is missing. It would be good to have these reviewed for an update.
