The EMD F7 is a 1500 horsepower diesel locomotive built by General Motors' Electro-Motive Division between 1949 and 1953. The F7 was EMD's fourth model in the line of F-unit locomotives and was by far the best-selling cab unit of all time. The F7 primarily differed from the F3 in internal equipment but there were some noticeable external changes such as the grills and the dynamic brake hatches. F7's operated in both passenger and freight service and many of them remained in service for decades. In this N Scale production we are modeling A and B-units from nine railroads with prototypically accurate road numbers and paint schemes. We are offering A-B sets with Powered A-units (w/ Paragon4 Sound) and unpowered B-units and also separate single A and B-units with our full Paragon4 DC/DCC/Sound system. All of our models have road-specific details and lighting. Road-specific detail options in this production prototypically accurate for each road name Pilot prototypical for paint scheme Operating Mars Light where prototypical Small horizontal and Large 45-degree numberboards Prototypical horn Water fill hatch location Sand fill hatch location Dynamic brake where prototypical Cooling fans and exhaust hatch accurate per each prototype Winterization hatch present where prototypically accurate Multiple MU door options on front of model Multiple options for skirts above fuel tank Ladder rest grab irons present where prototypically accurate Grab iron ladder present where accurate Eyebrow grab irons present where prototypically accurate Grab irons above cab side windows where prototypically accurate Roof antenna present and correct where prototypically accurate Front and Rear lift lug present where accurate Nose door number plate present where accurate Trainphone antenna present where accurate Industry-leading Model Features Paragon4 Sound & Control System featuring ROLLING THUNDER Integral Dual-Mode Decoder with Back EMF for Superb Slow Speed Operation in DC and DCC Precision Drive Mechanism Engineered for Heavy Towing and Smooth Slow Speed Operation All Wheel Electrical Pick-up ABS Body with Die Cast Chassis for Maximum Tractive Effort Premium Caliber Painting Prototypically Accurate Paint Schemes and Road Numbers Many Separately Applied Details such as Grab Irons Horns and Bell Prototypical Light Operation Prototypically Accurate Sounds for the EMD F7 Diesel Locomotive Metal Kadee-compatible Couplers (2) Will Operate on Code 55 and Code 70 Rail Minimum Operating Radius 9 inches Broadway Limited Imports is proud to introduce Paragon4 The new benchmark for premium HO sound-equipped locomotives.
