Posted by SLRT on Tue Aug 25 07:09:13 2009, in response to Trolley operation questions, posted by gbs on Tue Aug 25 00:57:01 2009. Some of your questions have already been answered, but I'll tell you what I know.1. What kind of controls did the trolleys have? Handles, like the subways, or foot controls, like the buses? Most had hand controls, PCCs have foot pedals similar to buses. 2. Who controlled the switches in the street that caused the trolleys to diverge or merge? Were there interlockings and towers? Most switches were electrically controlled by whether the trolley was drawing power or not from the wire when passing a specific point. All cars carried a switch iron for non-powered switches or errors. 3. There don't seem to have been special signals for the trolleys. Did they simply obey the traffic lights, like the cars and buses? They obeyed traffic signals. 4. Trolleys couldn't steer around obstructions. Did they always have the right of way? Always. Most people with IQs above that of a slug knew not to obstruct a trolley track. 5. Were there specific stops in the middle of the street, or did passengers wave them down wherever they were? Basically, you could hail a trolley at any corner. "Trolley Stations" were established during World War I to save coal and many of the signs were still up at the end of operations, but they had long since returned to "hail at any street corner" stops. |
