[PRCo] Changing Track Switches

[Herb Brannon]

As we know, PRCo/PATransit PCC car (using trolley poles) operators changed
automatic track switches by using the "Track Switch" control on the dash.
Now with the PAT LRV cars (using pantographs) the routes and switches are
set by computer. This is also true in Cleveland on the entire Red Line and
the Green and Blue (former Shaker Hgts Rapid) Lines as far East as E. 79th
Station. After that its back to old style manual control on the Shaker
lines. Now, SEPTA still uses trolley poles so the "Track Switch" on the
operators console is probably still there and is used. On the other hand,
most systems now use pantographs. Like for instance MUNI in San Francisco
and I'm sure they have a lot of switches to go through. My question is, how
do the systems using pantograph current collection change track switches? I
know how it's done in Cleveland, but not other places. Anyone know?
