Electricity on U. S. trunk lines

Although less than 2000 miles of railroad have been electrified in this country the present development of the new way of running trains is affecting a considerable proportion of the nation´s train service because it is used mainly on heavily traveled lines such as those of the New York Central, the New York. New Haven and Hartford and the Pennsylvania running in and out of New York City. Ninety per cent of the total railroad traffic of the United States is handled over a bare 10 per cent of the trackage and electricity is making itself felt on this 10 per cent.
