Story Contribution: Edwin Alexander, Adam Burns This video tells us about the design and development of the very first Steam Duplex locomotive concept. The B&O railroads class N1, #5600 George Emerson
yes the emerson style firebox it was a hybred it was a firetube but had a waterwall like a watertube around the firebox, but as you say vibration caused it leaking and the watertube part had issues with cleaning the limescale off the curves that made up the waterwall part of the firebox it had to be turbined out more often and it was harder to clean I read, but I think it was a brilliant attempt at engineering and use of space to get the most heating surface they could, problem is with most watertube boilers is they cant take the vibrations of railroad work as its not as ridged as the regular firetube boiler, not like a ship or a stationary boiler that would have one, now as for current projects mackwell locomotive works in new zeeland made a steam tractor and small locomotive version using a lematt style boiler and did away with the waterwall that is watertube and seems to be doing ok so far. of course if you like an interesting read check out the patents for watertube firebox locomotives you want to talk about complex good gravy its a litteral pipe dream as they have a lot going on and many parts and waterdrums
Could of been converted to a 4-8-4 but looking at the spacing it could of also been converted to a 4-8-6. this locomotive would of been a fun test bed for me if I was George Emerson. When the original design failed I would of been in the shop trying different Ideas. Of course I would of gone full ham on the British design and it would of been more in line like the Q2. this locomotive could of even had been a test bed for a Steam/electric traction set up. I love the design but man did George drop the ball.
Very sleek looking machine with the smooth boiler cladding, the Hudson shown in the video has a very Canadian look to it with the smooth boiler and rounded off cab and tender edges. Canadians indeed made the North American steam locomotive look a bit more uncluttered like the British locomotives, the B&O seemed to use the same practice for their premier passenger locomotives.
@@TheRailroadCrossing-SteamPower I grew up in the Cleveland area, I could never understand why that name was used. But that’s just me, but now I understand what’s going on with the team! Thanks for your insight!
Yeah, I thought it a bit odd that the PRR made the same mistake.. It's almost like they didn't bother consulting with anyone from the B&O on the design failures
