This is the St. Denis MARC commuter rail station in Arbutus, Maryland, a few miles away from my sister's new house at Linthicum Heights. Last year, when I visited the M.B. Klein model train store in Cockeysville, I was told that St. Denis appears to be one of the spotting locations with the most train traffic in Maryland. This inspired me to visit this place and find some trains there. The first train I caught is a very short CSX freight, but the rest of them are the MARC commuter trains, some led by a locomotive and others led by a cab car. A cab car remotely controls a locomotive pushing at the rear of a consist. This video also includes my first view of MARC’s newest locomotive model, the Siemens SC-44 Charger, which complies with the Tier 4 emissions regulations. While there weren't many CSX trains during my visit, I was still convinced to see at least a few trains, be they freight or passenger. That was a great trainspotting trip. I hope to visit St. Denis again for more CSX action sometime in the future.
