The main object of the patrol was to eliminate as many trespassers as possible, thereby decreasing the number of potential vandals and thieves. The Railroad Police Departments programmed priority patrol efforts during peak vandalism periods. Special equipment for patrol helicopters consisted of an electronic siren, a three million candlepower spotlight, and radio channels for the railroads. Three methods were devised to protect a train through a trouble area. A prior overflight was meant to startle potential vandals and make them aware that their activities were being watched. Trailing the train at a discreet distance was a technique used when apprehension of those attacking a movement was intended. Circling a train was used to prevent attack. This program proved so successful that it was established as a permanent operating tool of railroad police of the two lines.
