One of my favorite freight trains to photograph is the coke train off the W&LE into Baltimore. Really enjoy seeing all the older cars off of railroads which no longer exist due to mergers, etc.
There were a pair of hoppers in this scheme sitting on the bridge over I-695 at Halethorpe yesterday evening when I drove home from the B&O museum. I emailed Cory at Atlas and asked if there was any chance of seeing this scheme on their 90-ton hoppers in a future run; based on his response I think there might be a good possibility.
