Are there any examples of 21st century steam locomotives? Not preserved historical steam engines made in the 19/20th century but original 21st century steam engines.It doesn't matter if it's standard gauge or minimum gauge.

Central Pacific #63 aka The Leviathan, a replica of the locomotive of the same name that was present at the completion of the Transcontinental Railroad at Promontory Point, Utah alongside the Jupiter, completed in 2009. It was built almost entirely from scratch and has 21st Century safety features including air brakes, PTC, and an oil bunker.It's since been renumbered PRR 331 in honor of the locomotive that hauled
>>2005166well the design is about 80 years old but I'd count it
>>2005168So THIS is the power of rail autismhttps://en.wikipedia.org/wiki/A1_Steam_Locomotive_Trust>The A1 Steam Locomotive Trust formed in 1990 for the primary purpose of completing the next stage of the locomotive heritage movement, the building of a new steam locomotive from scratch>Some of the sums raised by covenanting were "unheard of" from railway enthusiasts>By May 2008, £2.5m had been raised and spent, and the gap to the required £3m had been raised to complete Tornado.
>>2005166Here, have a listhttps://en.wikipedia.org/wiki/Steam_locomotives_of_the_21st_centuryWith regards to the UK projects, some are scratch builds or mostly scratch but using some original or similar parts, and some are conversions of other locomotives, however more new builds are going to be needed over time as original locomotives continue to age, be worn out from use, and require more and more replacement parts to keep them operational. There's a Ship of Theseus argument about preserved locomotives with some people believing that they should be pulled from traffic if keeping them running requires the replacement of too many original parts, while the counter argument is that parts and fittings were routinely swapped between locomotives during their working lives and barely any made it into preservation with all of their original parts.Regardless of which way this argument goes, the skillsets needed to produce replacement parts or new locomotives need to be retained, especially as the original generation of preservationists who carried over the knowlege from the steam era continue to die off. There are younger folks being trained to replace them, but if those people are going to be sustained there needs to be enough consistant paid work for them for keep doing it, and new build projects can potentially play a big part in that. The problem is finding the money to do it during a time where rail preservation is increasingly struggling to remain financially viable.
>>2005607The amount of experimental and streamlined locomotives that can be built is astounding.
I would want to come up with an entirely new design for the sole purpose of beating Mallard's speed record.Would 150mph be possible with today's technology?
>>2005634i wonder if it would be more efficient to run a steam engine on propane?
>>2005634If it's American streamlined then yeah.
>>2005637Oil and coal burn hotter.
>>2005824does the temperature even matter for steam engines? i assume you can get enough pressure without excessive temperatures, especially in any kind of fire tube system.
>>2005824Propane would be lighter
>>2005702Good luck finding anywhere in America to run a train quickly.
>>2005634Hear me out: steam-electric drivetrain
>>2006078Liek dis?
>>2005452*hauled Abraham Lincoln's funeral trainDidn't realize that I forgot to write the end of this post
>>2006242Nah, where they use steam to generate electricity which is used to power the motors.Pic related, but with coal instead of uranium.
>>2006321the french did it
>>2005168Seing a website address on a steam engine triggers anachronism.
>>2005166>https://en.wikipedia.org/wiki/LNER_Peppercorn_Class_A1_60163_Tornado>completed in 2008https://youtu.be/-8fp8Gknm0w>the first steam locomotive to officially reach 100 mph (160 km/h) on British tracks in over 50 years
>>2005832Takes lots of heat to warm up that much water. Hotter fire warms it up faster. Gotta have high pressure to work efficiently.A low temp/pressure might be feasible in smaller scales
>>2005855Propane has more heating value per pound than coal or oil but less per cubic foot, plus it needs to be stored under pressure.>>2005832>>2008706Any fuel can burn hot enough. Flame temperature doesn't really matter unless you're using a radiant superheater, and I don't believe any locomotive boiler uses them (but I could be wrong). The problem in any boiler is getting steady combustion of the correct amount of fuel to keep up with steam production.

>>2005702I'd much rather they rebuild this than the T-1 desu
>>2005607Shame so many are in the united kingdom
The Bluebell literally just finished a replica of an LBSCR Atlantic.https://www.bluebell-railway.com/special/beachy-head-launching-britains-newest-locomotive/
>>2013835UK has a special love of steam
>>2005166A guy named David Wardale actually tried to build an entirely new class of steam locomotive in the 2000s that would be used to haul luxury excursions. The project got pretty far, detailed technical drawings were made and they were able to use computers to calculate its approximate performance, but he was unable to find steady financing.https://en.wikipedia.org/wiki/5AT_Advanced_Technology_Steam_Locomotive
>>2019566How much would it have cost?
>>2019567A lot, they never actually around to finalizing the design, let alone the cost per locomotive. It would have easily run into the tens of millions of dollars because of the need to fabricate custom parts
I made this in SolidWorks a while back.15" gauge
