The potentialities of railway electrification at the standard frequency

摘要

The paper discusses the technical and economic aspects of railway electrification using alternating current at the standard frequency. The authors accept that, for suburban traffic, d.c. electrification has provided a satisfactory operating, technical and economic answer, and they put forward the view that for new mainline projects the 50 c/s system is likely to be cheaper than other systems and may be installed without technical difficulty.
