Again, TARS-TATS foot-operated brakes are lift foot to apply and depress to release. So, somehow, they are both self-lapping and in series. Because, I assure you, one cannot remove the brake pedal unless it is at full height, meaning full application.
Coming to a terminal on a Third Avenue Transit pokle-equipped car, the procedure was:
Come to stop, including gradual release to prevent a "stone-wall" stop. The moment the car stops ompletely, release the pedal for a full ap;plication, which will also automatically open the front door and allow a passenger to stand on the rear-door treadle to opn it. Do not remove the pedal. Do move the reverser key to neutral and remove it.
When all passengers have left, exit the front door, raise what will now be the rear pole and reboard the car.
Tap the prdal very lightly, which closes the front door, and the rear if it is open, without releasing the brakes. Remove the pedal and, on older cars only (not sure about this) the cointroller handle) and carry all the "hardware" to the other end of the car, while flipping alll the seat-backs. Insert pedal, and also the handle if applicable. Tap the pedal with greater strength to open the door on the rebound, or if on a grade, use the door open button, openig the front door, Exit, lower and secure what was the rear pole, enter the car, insert the reverse key, move to forward, check to insure the line-switch overhead is OK, and begin loading passengers.
When all passengers are loaded and fares collected, release the brakes completely by pressing the pedal to floor while simultaneously applying one point of powe, no more. The door will close. Advance the controller slowly, not all at once, to reach the proper speed, and then back-off to full series if full parallel is faster than desired. Continuous running on anything but point one, full sxeries, or full parallel was discouraged.
On conduit lines, same minus pole hadling and the need to leave the car.
Straight air cars for the most part do not have self-lapping brakes.
On simple straight air cars the brake stands are normally set so the lap position is the middle, with apply to the right and release to the left. Brakes are applied by taking a "bite" (moving the handle to apply) and then returning to lap to hold the set braking level.
With self-lapping brakes the actuator (handle or pedal) is more like a car's brake pedal in that the amount of braking is set by the actuator's position. Cars with safety brakestands often had the door control integrated with the brakestand. TARS cars with foot operated brakes were self-lapping.
With train air the brake handle position is more or less the same, but the function is reversed, with "apply" releasing air from the trainline, and "release" allowing air into the trainline. There are both standard and self-lapping types of train air.
RC is correct about the hardware of the Scranton carsm
Straight-air d9ouble-endone pipe from the air-tank to the brake cylinders, or in parallel with separate pipes for each of the two valves. The fitst case requires that the valve be open, brakes fully applied, before the handle is removed, while the second requires thec valve to be closed m the neutral position/ Self=lapping streetcar brake systems were mostly of the second type, so RC is correct.
Also, my description of changing ends applies to streetcars having only straight-air air-brakes. The brake handles directly operate valves admitting air from the air-tank to the brake cylinders, similarly Third vAvenue's and Omaha's foot=prdel, raised to apply and depressed completely to release.
For cars equipped for MU. obviously the brake handle must be in neutral when removed, or "pumping-up" when putting the car back into service would be complicated, because of the reduction in train-line pressure means brake application. Thereis no train-line pipe with straight-air, single-car operation.
Of course the reverse key could not be moved from one position to another, unless the controller itself was in the "off" (no pwer) position.
What you describe seems accuratee for some or most one-man cars with self-laspping hand-control brakes.
Branford's (SLT's) Johnstown 357 was the car I would rarely run of that type.
The opens were two-man cars, and did not self-lkapping brakes.
Ditto for 4573, but we always ran it safely as a one-man car.
What you posted seems contrary to both maximnum safety and my own experience in operating cars at Shore Line Trolley and (foot pedal) at Third Avenue.
On the Connecticut Company opens and Brooklyn convertable 4573, removing the controlkler handle did not relate mechanically to the position of the reverser. But we were instructed to put the reverser in neutral first.
Thanks for the much more complete sequence.
daveklepperThe reverser kry can be removed only in the neutral position, and the brake handle or pedel only in the full-application positionh.
The reverser "key" has three positions, forward, off, and reverse. The controller handle can only be moved with the key in the forward or reverse position.
Answering your question: Because it's the line's terminal, and the operator is in the process of "changinhg ends."
You can watch this pocedure in most trolley miseums, those that don'l, like Baltimpre, have loops at both ends or just run on a distirted circle.
The operator brings the car to a stop with a regular smooth service braking application and the front-right door open, He then applies full baking effort. He moves the revesal key to the nuetral postition, then exits via the front right door and raises the pole. which was at the front and will be at the rear.
He reboards the car and removes the reverse key, and in some cases the brake handle as well. He shuts the right-front door without releasing the brake. He carries the "hardware" to the other end of the car, and as he walks down the center aisle, he flips the backs of the reversable seats.
At the new front end, he inserts the hardware, leaving the brakes applied and the reverse key in neutral and opens what is now the front right door. He exits, pulls down and secures what was the pole at the rear, reboards the car, and moves the reverse key to forward. After boarding passengers and collecxting or checking fares, he closes the door, releases the brakes and advances the controller.
The reverser kry can be removed only in the neutral position, and the brake handle or pedel only in the full-application positionh.
Note location correction on the previous posting.
It's "changing ends" with the operator moving to controls on the other end. The second pole is raised first so that pulling the first pole off the wire won't create an arc, which the current drawn by lights, heat or the compressor would cause even with the motors shut off.
Why does 401 have both poles up?

Excerpt from Email receoved:
Having reread my post,I realize, David, that I didn't acurately write what i meant to say. I was fishing around for your memories of the O&W itself. I wouldn't expect you to remember about that restaurant either. I am sure by 1950, the O&W DIDN'T have passenger service on the Scranton division. I have the one book on that line in my library. The late Jim Shaughnessy got some nice pictures of the line shortly before it sut down for good in 1957. They were in CT sometime in the last decade.
I probably did see the restaurant, but 70 years is a long time to remember the ispecifics. station/
Another thread has a picture or two at the D&H Carbondale. Still had passenger service to and from Scranton in 1950.
David, I'm sure you remember the O&W. When I began my seminary studies in 1972, there were still traces of it in Carbondale, about 15-20 miles north of Scranton. Recent trips show that just about eveything is gone. You probably know that Carbondale wouldn't let the O&W build through the town, so they built over the town! A Carbondale restaurant that my late wife and I used to frequent back in the day, was the old station.
Thanks David, I'll do that, but I still find it hard to believe someone's been to more rail action sites than you have!
Seems to me you started at the "American Railroads" display at the 1939 Worlds Fair and haven't stopped since!
Fintlock, to read and view great photos of someone who has been far more streetcar-frienndly places than I have been, visit the Trains Transit Forum, and pull up my postings on Jack May's visits.
David, seriously, is there anyplace you haven't been?
Great shot, loved them all! A good look at a saner time, that's for certain!
Beautiful! The one of car 509 in front of Thompson's Pharmacy looks like it was posed by Link!
Same me, different spelling!
