I had considered this, Fred, but I remember a fan-trip in the mid 50s
on M11. We were following a Library service car and had trouble keeping
up!
Also, even though the car is out of service, this car would probably
have to slow at stops where passengers are present. The potential
passengers will see the car and think it is in service and could step
across the tracks to be at the stop. A case in point: In the late 60s,
I was out in the AM rush in Pittsburgh taking photos along Drake. A 16
was coming thru and I was poised for my photo. The motorman was
intently watching me. I had considered stepping to the other side of
the track for the photo but decided to stay put. Good thing I did
because the motorman skipped this stop - passengers seemed to expect
this but I didn't and I was not able to judge his speed coming toward
me! Guess they did this to keep traffic moving fast with the long
sections of single track on Drake. Wasn't long before another car came
to pick up the passengers.
Even if a car has CAR HOUSE or out of service signs, this won't
necessarily convince the passengers that such is true. And on a line
where only one route passes by, people don't look at the signs, anyhow.
So the out of service car has to be careful where people are around.
Then there are the long stretches of street running on Charleroi and
some in Canonsburg. And what baffles me is that the slower cars are
more prone to traffic accidents than the *speeded-up* cars from what I
have read. Guess the faster cars got more responsive brakes, too.
This is fascinating information that you have pointed out about
control. I used to refer to the cars as *Jones-Cars* but Ed pointed out
that only us fans seem to use that designation and that they are more
properly called *low-floor* cars so I have used the latter term.
But according to your discussion, it appears as though some cars could
truly be called *Jones-Cars* because of the control packages they used.
This is getting very interesting.
I have heard about the control packages and would like to learn more.
Would like to get copies of the journal articles. Please advise of
costs, etc.
