Energy supply for electric railways

ABSTRACT ANOTHER paper read at the Vienna Sectional Meeting of the World Power Conference, by Mr. G. Lydall, a member of the well-known firm of Merz and McLellan, consulting engineers,

discusses the- requirements and the supply of energy for electric railways. It is divided into four sections. The first discusses the energy requirements for electric traction. Mr. Lydall

shows that these are much smaller than usually estimated. As an approximation he gives 50 kilowatt-hours per 1000 ton miles. In the winter months about ten per cent has to be added to this

for train heating. The second part deals with the consumption of energy for railway traction in Great Britain, giving figures for each electrified line, with the source of supply and the

half-hourly maximum demand. In the third part fluctuations of traction load and the ratio of the average to the maximum demand are discussed. Mr. Lydall states that, in general, for a new

scheme of electrification, it would not pay a railway to provide its own power. The Southern Railway derives its electricity from three sources, its own power station, a power company and

the Central Electricity Board. On the subject of the supply of energy for electric railways, fifteen papers were received by the Conference--four from France, two each from Germany and

Switzerland, and one each from the Argentine, Denmark, Japan, Norway, Sweden, Great Britain and the United States. Access through your institution Buy or subscribe This is a preview of
