Coming home from Seward on Saturday, I saw these to cars sitting in the Portage yard all by themselves. Having not seen these before of course my car turned immediately into the yard and out came the camera. 6/7/20

From ARRC sources - ARR 97843 is B&B’s high car for tunnel work.  In the past it was used it for placing clearance templates for the DMU and double stack cars.  One employee referred to it as "the hunting platform".
