Amtrak ordered the AEM-7 after the failure of the GE E60 locomotive to replace the GG-1 fleet. The first locomotives entered service in 1980 and were an immediate success, ending a decade of uncertainty on the Northeast Corridor.In the late 1990s, Amtrak rebuilt 29 of its locomotives from DC to AC traction. The locomotives continued operating through the arrival of the final Siemens ACS-64 in June 2016. MARC retired its fleet in April 2017 in favor of Siemens Chargers. Maximum speed: 125 mph (201 km/h). Power output: AEM-7DC and AC: 5,100 kilowatts (6,800 horsepower) maximum at rail, 4,320 kilowatts (5,790 horsepower) continuous at rail.
Tractive effort: Starting Tractive Effort. AEM-7DC: 53,924 lbf (239.9 kN).AEM-7AC: 51,700 lbf (230.0 kN) to 43 mph (69 km/h). M aryland A rea R egional C ommuter Transit (MARC) and the AEM-7. On October 1986, MARC began testing an Amtrak AEM-7 locomotive, looking to use push-pull trains to replace the Arrows. On February 27, 1989, MARC increased WashingtonBaltimore service from 7 to 13 weekday round trips.
A new park-and-ride station opened at Bowie State (site of Jericho Park station, closed in 1981) and Bowie station was closed. Two more round trips were added in May 1989. On May 1, 1991, MARC service was extended north from Baltimore to Perryville with intermediate stops at Martin State Airport, Edgewood, and Aberdeen. Between 1988 and 1993, MARC expanded service from 34 to 70 total daily trips across the system.In 1995, 800 parking spaces were added to Odenton station. From 1989 to 1996, the Camden Line had high ridership growth and substantial changes to its stations. A new station at Savage just off Route 32 was opened on July 31, 1989. MARC began service to Greenbelt station in May 1993, seven months before Metro began serving the station. On January 31, 1994, MARC expanded midday service on the Camden and Brunswick lines, opened Laurel Race Track station to relieve a parking shortage at Laurel station, and closed the underused Berwyn station on the Camden Line. On December 12, 1994, Muirkirk station (originally planned as South Laurel) was opened to reduce congestion on nearby Route 1. In July 1996, the Elkridge station was closed and replaced with Dorsey station, which has a larger parking area and a dedicated interchange with Route 100. On April 30, 1987, the B&O was merged into CSX. CSX continued to operate Camden and Brunswick Line service. On July 6, 1987, MARC opened Metropolitan Grove station - the first new station on the Brunswick line in over a century.

HO Scale Atlas MARC AEM-7 Electric Locomotive #4902 Powered new with box. The detail on the models is accurate and well rendered.All major dimensions are within an inch or two of those shown in drawings published in the June 1993 Model Railroader. The grids on the AEM-7 match those in photos. The glazing in the windows is clear and flush-mounted. Both cabs have interior detail, and one contains a crew. The pilots on each end have m.
Hoses and uncoupling levers and come equipped with Accumate magnetic knuckle couplers. Grab irons are separate steel wire pieces, and the roof detail is thorough with the bare copper wire a particularly nice touch. If there's any disappointment it's the resistor-grid housing, which represents the grids with perforations on the side sheets. Even this is adequate for all but close inspection.
At speed step 28 on an NCE PowerCab Digital Command Control (DCC) test setup, NMRHA sample reached 98 scale mph. This is a bit short of the top speed of the prototype, but still fast for a model railroad. In direct-current testing, the model reached 113 scale mph at about 13V, the maximum output of our Model Rectifier Corp. Further testing in DC revealed a starting voltage of 5.5V for sound, 7V for movement at 2 scale mph. Sounds were automatic, and the lights, including headlights, marker lights, and rooftop strobes, operated depending on direction.
Accumate(R) couplers, operating directional headlights and marker lights. Full cab interior with painted crew member.Separately applied wire grab irons roof detail and accurate painting and lettering. Also includes an integral switch on the circuit board which allows the modeler to select either the pantographs or track power for easy operation. Unit has been Track Tested and runs well. Atlas MARC MPN 8579 (Un-numbered).
Buyers prefering an un-umbered unit. Upgrading from DC to DCC.
HO-Scale decoder designed as a direct-plug replacement decoder for engines equipped with 8-pin NMRA sockets. By far one of the easiest decoders to install, the DP2X can be plugged into many locomotives with no effort. Provides superior slow speed control and high performance under load.Super-quiet motor control for "buzz" free motor performance. Decoder will automatically detect DC power.
You can also configure how your lighting effects function on DC. This feature allows the decoder to talk to the command station. RailCom supports expansion for new features. Allows you to make custom acceleration and deceleration curves. This decoder can be used with 12 Volt bulbs.
Buttons 0 through 12 may be used to control the lighting functions of this decoder. Choose from 20 separate user-programmable lighting effects! Configure multiple different brightness levels for your LED's or incandescent bulbs. Feature which prevents accidental/unwanted programming while activated.Fully compatible with Airwire operation. Configure custom speed curves and set speed limits. Use only Rosin core solder approved for electronics use.
