Modern trolley-coach operation

THE BOSTON Elevated Railway serves a population of about 1,531,000 people, distributed over an area of 111.56 square miles and segregated in 14 municipalities, including both towns and cities. Within its territory the railway supplies practically all of the public transportation, except taxicabs. The backbone of its system is formed by its rapid-transit division, with elevated lines, subways and some leased surface right-of-way. The rapid-transit lines are confined to Boston and Cambridge.
