One thing I forgot to mention when we did this is, some of the engines did later receive a shield that went in front of the cylinders on the coach end, the water brake if overused could result in water building in the cylinders and blowing cylinder heads off. It was a common enough occurrence that they installed the shields to prevent pieces from flying into the coach if they blew a head off.

Almost as complicated as the engines i fire on the Furka line in Switzerland. These are made for mixed use in adhesion and rack sections, the adhesion being a pretty normal engine and then having a Low pressure engine between the Frames to power the coqwheels. Also the automatic brake is Vacuum, and when going downhill we use the engine like a aircompressor to break, also using boiler water in the cilinders, but here it's to cool them, because air gets hot when it's compressed to 8 Bar in one stage

Check out the Mount Washington Cog Railway. This is a much older cog railway on the east coast located in the White Mountains in New Hampshire. The Mount Washington Cog Railway was opened in 1869 using a vertical boiler locomotive called Old Peppersass. This loco ran until 1875 when it was replaced with a more traditional-looking locomotive, the Ammonoosuc. This loco gained a partner in 1908 named the Waumbek. Due to the steep grades, the locos have tilted boilers that are actually level when they are on the steep slope. Both of these steam locomotives ran until 2008 and they have since been replaced with bio-diesels. Old Peppersass made a countrywide trip in June 2016. I saw the locomotive at a train fair in North Adams, MA. Compared to locomotives today, this small steam locomotive was very tiny and was carried on a standard landscaper-type trailer!

While I never rode on the trains, I did see them when two buddies of mine and I drove up to the summit. While up there, I was more interested in the trains than I was in the weather station and all the other stuff going on. That was way back in the early 1980s when I didn't have a lot of money and the tickets were expensive. I have to plan a trip up there to the White Mountains sometime next year. For me it's a 3-hour trip north.

This is a surprisingly wholesome and heartwarming video(even _if_ the grounds look like Permafrost took a sickleave due to the cold). I remember Cog trains from my childhood, as a passing glance and peripheral mention, never saw one or touched on the topic since my childhood.... having a whole video that touches on some of the finer mechanical details nigh-thirty years later really perks me up. Thanks! and have a like.

I remember seeing a picture of this engine years ago and noticing the weird cylinders. There used to be a few Vauclain compounds here in New Zealand, including a one-off 2-8-0 from Baldwin (OA 457) and a ridiculous 2-6-6-0 tank engine built at Petone Workshops in 1906 (E 66).

12:18, I think another thing is that you'll notice the pin is below center, so I think another part of that was to reduce strain on the rods and valve gear

Thanks Hyce, & Jjmmy. I really enjoyed the video of this unique piece of railroading history!

Reminds me of those trains that go up Snowden in Wales they use rack and pinion to get up the mountain. They are utterly amazing

I love your videos. That's an interesting point about slower combustion and the limited coal bunker. The compound system on such slow work would also have saved significantly on coal.

I've heard from someone that 4 may never get to run again. Pikes Peak replaced the rack so only their new trains can run on them. 4 would need new cogs to run.

Wow, Very cool information. I had no clue about these. Fascinating, thanks for shooting this.

Came over from Kan. Love the content! Cog trains are fascinating

This is cool, we lived outside of Victor for 3 years and rode the narrow gauge in Cripple Creek a few times, never went on the cog but that might have to change. PS the thread type you are looking for on the handwheels is "acme Thread".

11:30 if you look at the big lever that reverses the directions of the rods, the bottom length of the rod is significantly shorter. I think this allows for more torque/power per piston stroke.

@royreynolds108

Жыл бұрын

The piston stroke is longer than the crank stroke of the wheels or cogs. These locos only ran at about 8 to 10 mph. I think that is because of the cogs and rack.

The Snowdon Mountain Railway in Wales has some great looking rack engines, and a maximum grade of just over 18% (1 in 5.5).

I’ve been to the cog railway, nice and short line. Lovely place. Cannot wait to go back again!

Such a treat of an episode. Thanks!

Hey Hyce, rather new to your channel, I have been watching your Railroads Online stream with kAN, Anyway, just wanted to say that my Grandfather, Rudolph Pleger, was a machinist and I believe engineer for The Mount Emily Shay. It is currently being restored by the Oregon Rail Heritage Center and will be doing holiday Christmas runs in Portland OR, hopefully next year. To the best of my knowledge, it is the same engine. Grandpa worked at the Mt. Emily Mill for 27 years at Starkey and LaGrande machine shops and on locomotive repair. He retired in the early 60's but the engine itself was retired in 1955 and moved to Portland in 1957, where it became the property of the Oregon Historical Society. In 1972 it was leased to Cass Scenic Railroad in West Virginia where it was damaged in a fire that burned down the roundhouse, and became the object of a court battle when Cass refused to return it when it's lease expired in January of 1993. The fight over the train began in August and the engine was returned in May 1994. It was then leased to the city of Prineville where it ran for a number of years. In April of 2022 the OHS put out a request for a new owner when Prineville informed them they no longer wanted to run the engine. On August 24th the Oregon Rail Heritage Center was selected as the new owner and on September 1, 2022 they signed the paperwork. My understanding is that they hope to have her ready to run as one of the Holiday trains next year. 🚂🎅

I studied this locomotive quite a bit when I visited a couple years ago and it is a very interesting locomotive!! Thanks for doing this video!!

Here in Queensland, Queensland Railways (1067mm/3'6" narrow gauge) had an ABT rack railway in place at Mount Morgan southwest of Rockhampton from 1898-1952. However, the line itself from Rockhampton to Theodore was mostly adhesion based at 241.2km/149 miles long, but with 2.3km/1.5mile long rack section on 6% gradients. So they built their rack locos with standard chain and hook couplers and buffers and would mount them to the rear of the adhesion train as a banker to push the train up the slope, or provide safe braking and assistance to pull a train back down the grade. These rack railway locomotives were able to still drive properly on adhesion rail which made it cheaper to build and maintain yards and sidings because you could just run them through standard railway switches and easily just build a dedicated siding for the loco and couple it up to the next train. Really ingenious system and set up, but sadly the locos have all been long lost and scrapped after a bypass was built in 1952 with a 2% gradient to avoid bottlenecks on long coal trains and the still used original locomotives being due for replacement. They did use Garratts for a while on the line with 750t coal trains which would later be diesel hauled. The line itself also has since closed due to declining traffic and a faster, heavier and more modern line via Gladstone for coal and grain trains (Moura Shortline). If you're really into narrow gauge railways, I really recommend you check out Queensland Rail! At its peak it had about 9-10000km of track and to this day you can get 2km coal trains running on it and long distance passenger tilting trains regularly in some sections hit up to 160km/100 miles per hour.

The "thread-that-isn't-Ajax" is an Acme thread. Lead screws, jack screws: if it turns rotation into linear motion, it's likely to be an Acme thread.

The threads on that hand brake are square thread most likely since they looked like they didn't have any taper. If there was any taper in them with a flat top they'd be Acme.

I'd actually like to come down to the museum and learn about this loco.... an interesting piece of equipment, that's for sure.

I remember reading somewhere that the rod arrangement was like that because it gave it more leverage, aka torque or tractive effort. Since the top one’s longer than the lower one, which is the one actually connected to the cog wheel, I’m pretty sure it was right.

Very cool how the engineering of this locomotive is done

What a funky machine.

ACME Threads also used on some air brake systems on trucks years ago.

Interesting. I wonder if you would even need a valve on the upper end to switch the exhaust between the muffler and the stack? The vent to the muffler looks like it's got a slight downward slope, and even under pressure the exhaust would still have weight to it, so I'd think gravity would pull it to the lower vent first. Unless the stack had enough draw to create a vacuum stronger than gravity or if the lower vent didn't have enough clearance to release the pressure quick enough (though in the latter case you'd probably want it to vent the extra pressure out the stack as a release). If you designed your vent pipe with a backwards sweep towards the stack so that the steam is only getting directed there when the pressure in the muffler vent is full, that's probably all the direction it needs.
