LOCOMOTIVE INSTRUCTION MANUAL KRAUSS-MAFFEI
ML4000 DIESEL HYDRAULIC
The prototype:
In the early 1960s, American railroad companies D&RGW and SP were looking for
more powerful diesel locomotives to haul heavy freight trains on their lines
traversing the Rocky Mountains and the Sierra Nevada. Current units from EMD
did not meet what SP and Rio Grande were looking for, so both railroads
approached Germany’s Krauss-Maffei about building high-horsepower diesel-
hydraulic locomotives. Krauss-Maffei answered the call with their ML4000
diesel-hydraulic locomotives. Hydraulic power transmission, which was not
common in the US, not only provided the required power but enabled better
traction and a higher power-to-weight ratio. With a rated output of 4000 hp,
the six-axle ML 4000s were the most powerful single-frame diesel ocomotives
of their time. The D&RGW and the SP initially ordered three engines apiece,
which were exported to the USA in 1961. While still making frequent
modifications to these initial „Prototype“ units, SP placed an order with KM
in 1963 for 15 mechanically similar but very different looking „Series“ units.
The Rio Grande units were sold to the SP in 1964. Southern Pacific’s Krauss-
Maffei units remained in service until 1968.
