Subject: Re: Modern Steam Locomotives Author: Lew [ Next Thread | Previous Thread | Next Message | Previous Message ] Date Posted: 21:29:42 07/20/12 Fri In reply to: Greg B 's message, "Modern Steam Locomotives" on 16:57:13 07/20/12 Fri Both the Chesapeake and Ohio and the Norfolk Western fieled steam-turbine-electrics; the C&O had three Baldwin/Westinghouse units built to pull the "Chessie" streamliner train AN THE n&w BUILT 1 UNIT NICK-NAMED THE "jAWN hENRY". See http://www.wilkinsontrains.com/traindisp.cfm?train_id=195 for info one the "Chessie" train and http://trn.trains.com/en/sitecore/content/Home/Railroad%20Reference/Railroad%20History/2006/06/The%20Jawn%20Henry.aspx for the "Jawn Henry.

I'd heard of that engine, but I have no knowledge of British Railway systems. I see from your reference that she carried 4000 Imperial gallons of water and I was wondering if anyone would know how far she was able to go between watering stops? More than anything else water demand is the primary bugaboo for non-condensing steam engines. Of course maintenance is second in line to that because steam engines are not self lubricating like diesel engines are. (Actually external combustion just isn't as efficient as internal combustion, darn it, because I'd love to see steam engines running in mainline service once more!) kp

[> [> [> Subject: Re: Modern Steam Locomotives Author: Mike [ Edit | View ] Date Posted: 17:17:50 09/13/12 Thu As well as the Turbomotive (35-52), there was the Hush-Hush (allegedly so named to keep the project quiet, rather than for her sound) - see http://en.wikipedia.org/wiki/LNER_Class_W1 and http://www.lner.info/locos/W/w1.shtml I think she looked far better in her original guise (29-36), rather than the W1 rebuild (36-59) :( Sadly, she was never really given the chance to prove herself :( The boiler was replaced far too early - interestingly, it was used for pressure-testing and space heating for a further 26 years or so, so it couldn't have been as bad as claimed !
