Electric locomotive application

Electrical Engineering, 1941
ELECTRIC locomotives were first used for the movement of main-line traffic over 45 years ago. This early application was for tunnel work but it may be taken as the beginning of a new era in main-line transportation. In this era the steam locomotive has been transformed in appearance and characteristics.

The Design of the Electric Locomotive

Transactions of the American Institute of Electrical Engineers, 1910
The features to be embodied in an ideal electric locomotive depend entirely on the point of view. Any electric locomotive, however, must contain certain essential features.

Electrical Equipment for Rectifier Locomotives

Journal of the Institution of Locomotive Engineers, 1957
The single-phase 50c/s system of railway electrification has developed extremely rapidly and has been adopted in recent years by France, Turkey, Portugal, the Belgian Congo and Great Britain. Of the many types of locomotive possible, the rectifier type is becoming more and more widely favoured, owing to its combining the best possible traction motor ...

The development of the electric mine locomotive

Proceedings of the American Institute of Electrical Engineers, 1914
The paper traces, largely by means of pictures, the course that has been followed in developing the mine locomotive to its present condition. The paper is limited to locomotives for operation in coal mines. The two main factors which have directed the development are, first, the demand for increased entry capacity, and second, the exploitation of thin ...

Mechanical design of electric and diesel-electric locomotives

Journal of the Institution of Electrical Engineers, 1950
The paper deals with that part of the locomotive which may termed the chassis and body work; it does not concern itself with mechanical design of electrical apparatus. After surveying the physical limitations within which locomotives must be designed, the paper outlines the three main groups into which chassis design naturally falls, namely the ...

Maintenance of Diesel-electric locomotives

Proceedings of the IEE - Part IA: Electric Railway Traction, 1950
The question of maintenance is approached from the point of view trying to determine what are the basic principles which should govern the methods and standards of maintenance. It is evident that if sufficient care has been given to the design, then only those parts of the equipment which are subjected to fairly heavy stresses should require ...
