Yes, John's photos above show normal procedure, VRS usually has a single unit, CMQ may have a couple, depending on whether they run a local or 710 from Farnham/Richford down to Newport.
Service depends on CMQ delivery, which always seems to be unpredictable. VRS may either run 3 or 5 days a week, depending on whether they operate as a pair of daily turn jobs between White River Jct. and Newport, or as 1/2 units running through either north or south. They have done both this year. They will even run light engine between both points.
Columbia Forest Products is the only active shipper on the old QC, at the end of track.

Is there a sight worse than a rabid foamer sprinting towards your clean photo/video angle with a tripod, so he can set up two feet from the rails?
