Electrification Progress in Switzerland.

Electrification of railways was, at the outset, mainly confined to city and suburban lines, such as those of the Paris Metropolitan system. page 20 Nowadays, main line electrification is expanding in many lands, and in mountain-locked Switzerland, there are to-day actually 1,700 kilometres of main line worked by electricity. For the years 1930–1937 the Swiss Government Railways have drawn up an elaborate electrification programme involving an expenditure of about 80 million Swiss marks. During this period some 500 additional kilometres of track are to be converted from steam to electric traction, the longest single length of line involved being the 84 kilometre stretch of track between Berne and Lucerne.
