Economics of trolley-coach operation

SINCE the introduction of the modern trolley coach in 1928, it has demonstrated in almost every installation its ability to increase revenues and to operate at very low cost. The investment cost for trolley-coach service is low, and the quality of that service ranks very high compared to other transportation media. The vehicle itself and the materials used in the distribution system have been improved continually with resultant improvement in the financial showing. Further progress is under way.
