The other day I was at Union Stations and I saw the Corridor Clipper car parked in front of an Acela Express train set.

While I have no idea if it was related to the Corridor Clipper car or not, there was a bunch of security to right if you were walking from the Acela Express train (near the VRE/MARC train area) and I thought that maybe the car carried high value dignitaries (Like VP Biden)?

Does anybody know the official role of the Corridor Clipper car? The windows were blacked out and it seemed that whatever purpose the car served AMTRAK did not want the common citizen to know about it.
