In the late 1960's, MLW developed a new generation of "M" line motive power featuring modern, modular design utilizing high-adhesion trucks, unitized air brake system, AC generation, transistorized electrical control and improved chassis systems. The latest arrival is the M420-M427, four axle, four-motor, 2000-2700 HP series which today appear to be the popular models. The M420-M427 is a very flexible design which can be built in weights varying from 240,000 to 272,000 lbs with fuel capacities up to 4000 U.S. gallons. This model, with a 60,000 lb continuous tractive effort capability with 65 mph (74:18 gearing), is powered by the 12V251 diesel engine which has a 2000 to 2700 HP for traction capability. It is 61 feet long, with 56 cu. ft. of sand capacity. Details are given.
