4 Auto Carriers in Perryville MD

I have been noticing 4 Auto Carriers ( 1 NS, 1 UP, 1 CSX + 1 other) that have been set off on a siding just before the Susquehanna river bridge in Perryville MD. They appear to be empty. They have been there now for almost two weeks now. Why would they have been placed there? Anyone have any info on these cars? Thanks!

Empties - 4th car from rear of train got a drawhead out of the 'wrong' end of the car and all 4 were set off.

What does that mean? drawhead? And how long till they get moved? Thanks

Drawhead is the entire coupler assembly - the shank to the knuckle. It is in the hands of the Car Dept to make the necessary arrangements to effect repairs.

The Perryville Connection track is out of service by MofW decree at the present time. Crew will need MofW assistance to move the cars off the Connection. Getting crew, MofW and Car Dept all on the same page at the same time can be difficult.
