That eccentric mechanism to control a regulator - great idea!

Love your practical ultra-minimalist engineering style. Excellent video.

Thanks so much! Really cool to see your equipment and how it all works.

I cannot get enough of this stuff!

Cool evolution of a simple mecanism.

thanks for the video, you do a great job of going through the details, great designs

This whas just what i was asking for! Great video!

Thank you!

Great update - thankyou

Very similar to the air braking on the Peter Witt streetcars in Milan (later streetcars had either electric + air braking, or "all electric"). But the strangest I've seen was in Bremen (Germany) on an historical streetcar (type "GT3", itself an uncommon build being an articulated unit with 2-axle truck + single axle trailer); the braking was electric but to really stop the motorman had to turn a wheel, that activated the braking shoes via gearworm and chain).

Very interesting, thanks for sharing!

Very interesting that the cars use a manual air pump input instead of a pressure sensor for automatic refilling, a far cry from the full size cars but interesting none the less! An amazing video, keep up the hard work my friend!

The compressors do have a pressure switch, the main reservoir is maintained at 100 PSI

I have been watching all the videos of the RRVT and totally enthralled. I've never seen anything like it, certainly nothing like it over the pond here in the UK. So rustic but functional. However, a silly question, what is it used for. Does it have a commercial function or is it just for pleasure? Can't wait for the next video!

Очень интересно. У вас все получится.

great !!

These videos are very educational .Look forward to the next one.

I have to say even I agree with that lol

Those ex M/W car valves look like SA-9 type NICE hardware!!!!! A proper gauge also. COOL!!!!!

I do like those gauges :)

As far as I know, a lot of old MoW equipment such as handcars and speeders used wooden shoes too. I've operated a pump car with wooden brake shoes, however the application is provided by the weight of the user pushing down on a foot pedal. A person's full body weight only does so much, you have to plan stops ahead. By contrast, I've run a Fairmont M14 on many occasions now which uses a hand lever, but the brakes can be applied much harder due to some mechanical advantage in the design, and it's incredibly easy to lock up and slide the wheels. Do the RRVT's electric cars have enough weight to prevent sliding the wheels under normal break usage?

interesting, guess my thoughts of re using and repurposing motorcycle or car bake shoes isn't nessasery

The maximum cylinder pressure is set so that the wheels wont slide under normal conditions. However, with wet or foliage covered rail then wheel slide is still possible. I try really hard to not slide them, but sometimes coming down the hill its a challenge to not do it if there is anything but ideal adhesion conditions. This is part of the reason I want to add cylinders to some of the heavier freight cars.

We did experiment with a motorcycle brake system on the curved side car when it was first built. It completely self destructed and locked up after a short time, I think we might have grabbed one from too small of a motorcycle lol

The newer valves appear to be Rexroth H-2-Fx Controlair, with the "b" output plate (the bit with "in" and "out"). Do you have the Part number? There are a bunch of PSI ranges these valves can have, and as these came off MOW stock, I'm curious what these are.

@CNW4145

Thats exactly the part number of these, the output is 55 PSI

How long to the wood break shoes last before needing replaced? Do you ever see smoke from the wood?

The very first shoe we ever put on still has some life left in it, that one has been on there for 25 years! The force is low enough that there is not enough heat to make any smoke.

Only this was a business that employed people, rather than a hobby. As hobbies go it's probably less dangerous than riding a motorcycle in traffic. :)

We have worked 27,010 days without a lost time injury, the number speak for themselves :) That's 74 years if you don't want to do the math lol
