MARC, prior to 1984 known as Maryland Rail Commuter Service, is a Regional rail system comprising three lines in the Baltimore-Washington Metropolitan Area. MARC is administered by the Maryland Transit Administration (MTA), a Maryland Department of Transportation agency, and is operated under contract with CSX Transportation and the National Railroad Passenger Corporation (Amtrak). Unlike many other commuter rail services around the country, MARC does not operate on weekends. Service is suspended or reduced on select holidays.
MARC operates 87 weekday trains on three separate lines: the Brunswick Line (19 trains), the Camden Line (18 trains), and the Penn Line (50 trains).
The Camden Line runs between Washington, D.C. and Baltimore, Maryland (Camden Station), operating over the CSX Capital Subdivision. It began operation in 1830, making it the oldest passenger rail line in the U.S. Stops on the Camden Line are:
The Penn Line runs between Washington, D.C. and Perryville, Maryland on Amtrak's Northeast Corridor and is the fastest commuter rail line in North America, with trains (consisting of bilevel cars and electric locomotives) operating at speeds of up to 125mph. It is the busiest MARC line, carrying more passengers than the other two lines combined. On weekends (all day) and weekdays (before 6am and after 10pm) most Amtrak Regional trains will accept MARC monthly and weekly tickets at Amtrak/MARC stations on the Penn Line; also some Amtrak trains carry all MARC ticket holders boarding at Aberdeen during the week. Stops on the Penn Line are:
As the Penn Line is the only electrified MARC line, the AEM-7 and HHP-8 are restricted to that line. The majority of the Kawasaki cars are operated on the Penn Line, and the Pullman cars are only operated on Brunswick Line trains to Martinsburg. All MARC trains are operated with a cab car, from which the engineer can control the train. The cab car is typically located at the head of trains traveling toward Washington D.C., and the locomotive is at the head of trains heading away from Washington. In the early 2000s a single unpowered EMD F cab unit, #7100 (ex-Baltimore & Ohio Railroad F7 #4553) occasionally substituted for a passenger cab car.
In Spring 2008 MARC placed an order for 26 new MPI MP36PH-3C diesel locomotives, which will replace MARC 70's-era GP40s. The new locomotives are scheduled to begin arriving in November 2008. To cope with increasing ridership, the MTA announced in August 2008 the acquisition of 13 additional Kawasaki bi-level passenger cars from Virginia Railway Express, to be placed in service by November 2008. The $22 million purchase is a ten percent increase of MARC's previous fleet size of 122 passenger cars.
The BWI Rail station is close to Baltimore-Washington International Airport (BWI), though not actually in the terminal itself; a free shuttle bus carries passengers from the station to the terminal every 10 minutes between 5 AM and 1 AM and every 25 minutes between 1 AM and 5 AM.
On February 16, 1996, during the Friday evening rush hour, an eastbound MARC train headed to Washington Union Station collided with the westbound Amtrak Capitol Limited headed to Chicago via Pittsburgh. The collision occurred at Georgetown Junction on a snow-swept stretch of track just west of Silver Spring, Maryland. The crash left 11 people dead aboard the MARC train. Three died of injuries suffered in the impact, with the rest succumbed to the ensuing smoke and flames; the MARC engineer and two conductors were among the dead.
The NTSB report concluded that the MARC crew apparently forgot the restricting signal aspect of the Kensington color-position signal after making a flag stop at Kensington Station. The engineer of the Capitol Limited also apparently increased speed rather than braking in an attempt to make the crossover. The MARC train was operating in push mode with the cab control car out front. The Amtrak locomotives were in the crossover at the time of the collision; the MARC cab control car collided with the lead Amtrak unit, an F40PH, rupturing its fuel tank and igniting the fire that caused most of the casualties. The second Amtrak unit was a GE Genesis P40DC, a newer unit that has a fuel tank that is shielded in the center of the frame, so a few seconds' difference might have prevented the fire. The official investigation also suggests that the accident might have been prevented if a human-factors analysis had been conducted when modifications to the track signaling system were made in 1985.
On June 29, 2007, around 5:15 p.m., a woman was struck by an oncoming MARC train headed to Martinsburg. The incident occurred in the Rockville area, and caused major delays to other trains online, with service resuming about two and a half hours later. The incident was investigated as a suicide.
On February 7, 2008, a MARC train derailed at Union Station after it was hit by an Amtrak switcher locomotive. The train was still unloading passengers at the time of impact, and seven people received minor head and neck injuries. The Amtrak locomotive attempting to couple to the train was reportedly moving too fast. On the same day, a trespasser was hit in Gaithersburg by an express train headed towards Martinsburg on the Brunswick Line, shutting the line down for two and a half hours.
In the past, the MARC trains have made special weekend trips to and from Cumberland, Maryland. Past events have included trains for Western Maryland residents to attend sporting events in the Baltimore/Washington Area, such as Orioles or Redskin games. Or Events for Baltimore/Washington residents to attend the Railfest in Cumberland and enjoy the scenic mountains and fall foliage of Western Maryland.
In the 2000s, MARC ridership increased significantly, and the system neared capacity for its current configuration. With the area population growing and the BRAC process poised to bring new jobs to Aberdeen Proving Ground and Ft. Meade, both of which are served by nearby MARC stations, the state saw the need to expand MARC service to accommodate growth. In late 2007, MTA Maryland unveiled an ambitious 30-year plan of system improvements. Though funding sources still need to be found, the plan represents the state's goals of increasing MARC capacity and flexibility. Proposed improvements include:
While many of these proposals would require expensive capital improvement and years or decades to implement, the agency would like to put others into action as quickly as possible, suggesting that, for instance, Penn Line weekend service could begin as early as 2008.
