[PRCo] 1019

[Jim Holland]

Looking for a specific photo of 1019 All Over The Web  --  Only to find 
it in my own collection!!!     It is emerging from the Tunnel at SHJ OB 
on a charter:
.
1959.06.14 -1019 Last PRMA West End trip: 26, 34/31, 30, 27, 21, 39, 47, 
44, 42, 38, 38A, 35.
.
The contraption on the left contains pushbuttons to activate the turnout 
and interlocking in case the switch is  *Missed.*
.
Note the dual overhead contactors for operating the turnout  --  the 
very first one is right at the tunnel edge and the operator does what is 
necessary to set the switch for the desired direction but nothing 
happens to the turnout until the trolleypole hits the second 
contactor.     The turnout will set according to what transpired at the 
first contactor and Regardless of what the operator did passing through 
the second contactor.
.
For PRCo it was coast the contactor for Straight Through - push the dash 
toggle on PCCs or power through on the older cars for Diverge.     I-F 
the operator Coasts the first contactor he can power through the second 
contactor and the turnout will still set or remain set for Straight 
Through.     Whether the first contactor also set priority for 
interlocking at this location or whether that was strictly track 
operated circuitry is unknown to me At This Time.     That works in 
reverse as well - Dash Toggle or Power through the first and coast 
through the second and the turnout still sets for Diverge.
.
This dual overhead contactor system was also used at other locations 
throughout Pittsburgh by PRCo but only a couple will be mentioned here  
--  Dawn Jct OB which was also US&S interlocked, Brookline Jct OB, 
Forbes and//or Fifth near Craft Ave Car House and others.
.
These people probably got lost as did Charlie on the MTA in their search 
for the Subway to Wilkinsburg~!~!~!
