With daylight time back in effect I could catch about three passenger movements within a single one hour window. Also included in this set was a trip to the old HX tower about a mile east of St. Denis, some photos around DC Union Station and some photos and video from the Baltimore Belt Line. You can find the full set of photos here.
The MARC Camden Line doesn't have a lot of service and the St. Denis station in particular has even less. Of the six peak direction trains, only 3 stop at St Denis with all of the reverse peak bypassing the stop as well. Arriving before the first train of the day returned from DC I only saw one car in the lot when typically most MARC stations are overflowing into the adjacent residential areas. One big reason is the close proximity of the faster Penn Line Halethorpe station that likely siphons off anyone with a vehicle.
ST DENIS interlocking was constructed in 2006 as a replacement for the older HALETHOPRE interlocking about a mile to the east. This lengthened the storage area for inbound trains to the southern Baltimore Terminal yard complex that branches off at WEST BALTIMORE interlocking. Here we see an Approach Medium indication displayed for an eastbound train on Track #2.
A non-stopping westbound train then arrives with MARC multi-level cab car #8049 on point and MP36PH-3C #28 and SC44 #85 providing power. At this point the SC44 Charger locomotives were still undergoing testing and had to be paired with the existing locomotive stock.
View of the train as it rounds the sharp curve west of the station. Just out of sight the OML will split from the Capitol Sub just east of the Thomas Viaduct.
The first train back from DC arrived with a single SC44, #83, on the front. It stopped and discharged a few passengers.
Alighting passengers must wait for the train to depart before crossing the tracks via the duckboards to get to the small parking area on the westbound side.
Here we see single level MARC cab car #7762 passing the subdivision post between the Capitol and Baltimore Terminal subdivisions.
CSX #ES44 #973 and AC4400 #11 ran light through ST DENIS interlocking after detaching from a coal train. The engines will now run back to to some yard for servicing. Note the Restricting signal indication for the light engines and a Medium Approach Medium signal for what turned out to be an approaching freight on Track #2.
