[@ZeldaTheSwordsman]

It's less shrinking it, and more designing the locomotive in a way that made slapping more on hard.

[@ZeldaTheSwordsman]

Which, in the original context these were designed for - increasing pulling capacity on mountainous narrow-gauge railways while keeping the engine's footprint relatively compact and needing only one crew - was an acceptable tradeoff.

@@jpgiebl Yes good point.

[@Desmaad]

The actual problem he was trying to fix was how to get more powerful engines on narrow-gauge lines, which are often cramped and twisty.

[@ronfisher2-railwaytravelvideos]

There was a problem and it did exist. Traffic on the 2ft gauge Festiniog Railway had increased to the stage that the line desperately needed extra capacity. This could have been done by converting it to double track, or converting it to standard gauge. Neither of these options were practical without vast expense because much of the railway was built on a narrow shelf cut into the hillside. Double-heading was one solution, but this was expensive because it took two locomotives and, more importantly, two crews. Robert Fairlie thus had the idea of two engines back to back; this saved using two engines double headed. He also had the idea of mounting it on bogies as the Festiniog line is very tortuous with sharp curves; the existing single engines at the time were 0-4-0T/Ts. His Double Fairlie design only needed one set of enginemen, thus saving on the wages of a second crew. So there was a problem, and it did exist. He solved it, and the Ffestiniog Railway is still using Double Fairlies to this day. In recent times it had built two new Double Fairlies (EARL OF MERIONETH and DAVID LLOYD GEORGE) with a third, JAMES SPOONER, currently under construction in its Boston Lodge Works. There are plenty of videos of videos of Double Fairlies hard at work on the Ffestiniog & Welsh Highland Railways on KZbin, including on my channel.

[@CPD0123a]

@@whispofwords2590 they were most definitely not rare on mainlines. Yes, very few class 2 and 3 lines had articulated engines, and most used second hand engines from class 1 lines. But all of the class 1's had swapped to using articulated steamers for heavy freight, and only using traditional ones for fast freight and passenger service. (Excluding oc the PRR T-1) So yes, across ALL lines, they would be rare. But on mainlines, they were staples. The only reason why they didn't become even more common was because the diesels popped up almost at the exact same time. It was well known to the mechanical engineers that they were working on a dying breed, and they really poured their hearts and souls into the beasts. Had there been more time until diesels took over, there would have been even more articulated engines. PRR T-1, PRR Mountain and others, C&O's Mountain and another one or two, N&W had some. UP had the Big Boy and Challenger. SP had some including the Cab Forward. Santa Fe had several types. B&N had them. Really I think that basically all of the mainlines were using articulated engines en masse before the end of steam. Heck, there's plenty of videos of Horseshoe Curve with trains being pulled by 2 and 3 Mountain types each, while other trains with articulated engines go the other way, and fast freights and passengers with K-4's go on the other tracks. Oc now they're rare bc they were a crapload of scrap metal when they left service. It's one thing to write off a few k4's to preservation, it's another if it's a Mountain.

Correction: articulated locomotives actually _did_ catch on to an extent, as a method of building a larger locomotive that can still navigate tight turns. The UK was one of the few places where such designs didn't take off well. Notable non-American articulated locomotives include the massive (by meter gauge standards) SEG Mallets, the Saxon Class XV and the South African Garrets. To note, many non-American examples of articulated locomotives are narrow gauge and used specifically to pull heavy loads at low speeds through mountainous regions.

There were actually 3 Single Fairlies built for the surrounding Ffestiniog railways. The first two were 0-6-4T (that you showed) named "Snowdon Ranger" and "Moel Tryfan", both built in 1875. These originally worked on the NWNGER, which became part of the Ffestiniog Railway eventually. After both engines being worn out by the late 1910's in 1919, Snowdon Ranger was scrapped and major components being used for Moel Tryfan. Moel Tryfan lasted for another 30 odd years being transferred to the Welsh Highland Railway in 1922 then being scrapped by the FR in 1954. The third one went by the name "Taliesin" and was built in 1876 for the Ffestiniog Railway. Unlike the other Single Fairlies it was of 0-4-4T configuration. It had a much shorter life as between 1898 and 1900 it was dismantled for preparation for a new boiler, but the boiler never came due to the Board refusing to purchase a new boiler. It was subsequently scrapped but a testimony states that it was however reassembled with the existing boiler but there are no record of this. While I said 3 there is technically a 4th but it is a new build of Taliesin named "Taliesin III" which was built in 1999. As of 2020 it is currently not in service receiving an overhaul.

I think I know how to fix the problems with the Farlie (I’m not an engineer in the slightest so don’t take anything I say seriously) 1. Add leading wheels 2. Add two sets of controls. One on each side facing each direction. 3. Make them burn oil so they can have tenders. Pipes will bring the oil from the tender similar to southern pacific’s cab forward locomotives. 4. Use them mostly on shorter runs where there isn’t a lot of time to turn around. The way you would turn them around is by using three tracks. One for the consist, one for the tender and one for the locomotive. The locomotive would leave the train on the first track. Then it would leave the tender on the second track. Then the locomotive would use the third track to move to the other end of the tender (which would have all the same connections as the front )(the locomotive would also retain the onboard fuel and water tanks to allow it to do these maneuvers.) Afterwards the locomotive would then move from the second track to the third track and couple back up to the other end of the consist and leave the station.

The Fairlies worked well on the Festiniog, which was very narrow gauge ( 1' 11 1/2" ) and had an extremely 'tight' loading gauge. Originally operated by horse traction (uphill) and gravity (downhill). The Fairlie was probably the first design that offered enough power to be useful. The Festiniog thus demonstrated that railways could be built relatively cheaply in mountainous countries with narrow gauges, and operated successfully by steam power. This was why Robert Fairlie gave the Festiniog a free license to use his design. The Festiniog line was only 14 miles long, so fuel capacity was not a problem. The small wheels (had to be small to fit under the frames) gave good traction but limited the speed - but on this line with its short length and sharp curvature, speed was not important. Very much 'horses for courses'.

No. 2 Double Fairlies were built on the Ffestiniog during it's opperational years, Merdden emris in 1879, and Livingston Thompson in 1886. The latter is now at the National Railway museum. However since the Ffestiniog was re-opened, 2 more Double Fairlies have been built on the railway, with a third currently being built. so in short, 4 Double Fairlies, soon to be 5 have been built on the Ffestiniog Railway.

[@howardrisby9621]

As well as No.7 "Little Wonder" (very much a working prototype, hence it's early withdrawal in 1883), there was another on the original line. No.8 "James Spooner" built by Avonside in 1872. Much of the valve gear on No.3 "Livingston Thompson" (the one at the NRM) comes from this lost loco, broken up in the 1930s. The most recent of the present day company's double locos carries its number and name. There's also a modern Blodge-built single Fairlie 0-4-4T, "Taliesin", a recreation of another FR loco scrapped at around the same time as No.8 (currently underoverhaul, expected back in service back end of 2024). Elsewhere, a private group are recreating another long scrapped (NWNGR) single Fairlie, 0-6-4T "Gowrie", the original being Hunslet built and sharing quite a few components with preserved NWNG/WHR 2-6-2T "Russell", now resident at the Welsh Highland Heritage Railway. It's worth noting that Blodge continue to refine the Fairlie concept, with use of superheating and recent design improvements to brakes, flexible steam pipes and bogie pivots and the use of monocoque cylinder blocks. Regular workshop/shed tours operate, see 'festrail.co.uk' for details

If I had to create a new steam engine, I would create a similar concept than the Double Fairlie except that it would be longer, the common point would be the fact that it would be double-ended but here are the differences : there would be a gap between the two ends so there would be two engines instead of one; each "end in the cab" got a firebox and each end have their own coal compartment and water tank... Would that be a good idea or not ?

Actually, the first locomotive you showed was German, and was designed to go forwards and backwards.
