A new signal bridge has made it difficult to get a good shot from the Route 1 bridge. Unfortunately, when the new bridge is activated, the B&O CPLs at HX will be removed from service.
Running a few minutes late, 173 highballs through Baltimore. This train and Q171 are some of the most reliable trains I've seen on CSX, both regularly ran at nearly the exact same time each day.
Shortly after Q171's passage, 173 makes a run through Baltimore on the Philadelphia Sub. The CPLs at this location guard the east end of Mount Royal siding.
Q173 passing by the Shepherd Junction signal on the Alexandria Extension. The old Benning Yard office building is on the left. A track realignment is planned for this area.
