MOTALA DIESEL-TURBINE LOCOMOTIVES

Distinctive features are: (a) The traction characteristics are those of a gas turbine combined with mechanical change-speed transmission from a reciprocating oil engine. (b) A smooth and gradual start, with high effective adhesion values, is always possible. (c) Though there is some complexity in the control construction, the transmission is essentially simple, with interdependent and automatically operating constituents. (d) There is no short-time or continuous rating of the transmission. (e) The principal constituents are all machines well tested and proved in railway service. (f) The simplicity and lightness of all constituents gives an inherent favorable power: weight ratio for the locomotive. (g) As the system in a sense is the equivalent of a non-pressure-charged engine of four-stroke type working in a high-pressure atmosphere, and with the compressor tied to the charging and turbine systems, the operation at high altitudes can be very favorable. (h) Dynamic braking is inherent in the system and without the addition of any cooling or heat-dissipating elements.
