Good Morning!

I had promised some photos of PRCo hardware that I have and have 
assembled a little walk through of that as well as some model photos and 
some prototype photos.       So lettuce begin:::::::




01 - Controls.       This is a crude set of PCC controls built about 
1968.       I designed and built a transistorized throttle which allows 
for separate functions for braking and acceleration.       Construction 
used threaded water pipes for Deadman on left and Power Pedal on right - 
threads allowed movement of the pedals.       Brake pedal was simple 
water pipe which slipped inside a larger fitting.

Deadman simply broke the circuit and was an immediate shutoff if needed.

Transistorized throttles use a capacitor to continually feed power to 
the Overhead when the power pedal was released; a simple cable from the 
power pedal to the acceleration pot was employed.      A trim pot 
allowed for the adjustment of coasting.       Brake pedal worked 
similarly as acceleration  --  simple cable between pedal and brake pot 
which then bled power from the capacitor which in turn lowered voltage 
in overhead.       Rate of braking and acceleration was 
adjustable.       It was tremendously exhilarating to operate in this 
fashion  --  I literally sat there for many hours on end!

I used an overhead contactor to set all turnouts but Only the one being 
approached by a TrolleyCar would set - coasting would set or keep the 
turnout in the straight through position - activating a toggle on the 
control panel just directed power to the other coil of the switch 
machine which would be equivalent to drawing power through the overhead 
contactor which would set or hold a turnout in the diverge position!



02 - A photo of Prototype controls.

PCC Motorman Seat  --  sitting on it right now  --  has been my desk 
chair for about a quarter century!

Motorman Gang Switches on the seat  --  several of those here from SF PCCs.

A set of Real PCC Foot Pedals from an All-Electric PCC!!!

Accompanying Reverser.

Earll  *-Retriever-*

PRCo Transfer Stand which holds 3-books of transfers with holder for 
extra books or for transfers collected.

Illinois License Plate for PC 1776  (had a Vanagon Camper here in CA 
with  PCC TRLY  for a license plate!!)

PRCo Electric Fare Register from either 1100 or 1200 series PCCs.



03 - PRCo Manual Fare Register.       Have mentioned this in previous 
posts.       This was in worse shape than the electric register in the 
previous photo.       Both registers were disassembled and the shells 
were stripped, cleaned, then primed and painted.       Each coat of 
primer and paint was baked in the oven at the lowest temperature setting 
and 20+ years later these items look like new.       PCC Op Seat 
repainted  (but Not Baked In Oven!)  as well as voltmeter and sundry 
other hardware.



04 - This is an PRCo Jones Low-Floor Shell in 1"=1' or 1.12 scale!       
My dream has always been to also have an PRCo PCC Interurban in 1.12 and 
then operate these models through the foot pedals shown above.       
With Radio DCC that is a very real possibility!
