I muse on how, many things might be different in a future where the oil is exhausted -- perhaps less of a difficulty re the "dirty, nasty brute grunt labour" aspect of steam locomotives: no more oil and no more motor vehicles would likely mean fewer jobs, with more people chasing the jobs that there were, no matter how horrible... steam-loco cleaner perhaps preferable to 19th-century-type farm labourer? ... of course, operational and economic efficiency would be important factors vis-a-vis revived steam rail traction.Cochise said:I've read a lot about the Leader. It could never have been more than a test-bed without major redesign, although the power bogies seem to have been reasonably successful.
Chapelon and Porta have demonstrated the necessary thermal cycles for a more efficient steam engine, but the actual physical layout would be more contentious, and cleanliness and ease of maintenance would factor in. Wood burning - maybe with pelletised wood - could be a lot cleaner.
Availability would need to be addressed - perhaps some kind of cassette system for ash disposal and obviously water treatment for the boiler. You'd want a loco that could run at least 18 hours in service a day without need to do more than top up coal and water.
Coal burning would presumably use some kind of mechanical stoker, and one assumes that we would, like Bulleid with the Leader, be aiming for one or two general purpose types rather than the plethora of designs that were produced even in BR days. I assume that electronic controls would obviate the need for the fireman to actually be at the firebox end of the boiler, so maybe something like a modernised Beyer-Garratt with cabs at the outer ends would do the job. Or perhaps the Leader with a conventional boiler, Chapelon/Porta steam cycle, and without the rather pointless cladding.
It could be done. Will it? I very much doubt it - another human failing is never looking back to see if abandoned ideas from the past could be developed further. Instead we get energy-wasteful nonsense like maglevs and monorails.
Re your last paragraph -- I'd tend to disagree a little. "When push comes to shove", humans are adaptable and pragmatic -- I see them as being able, in desperate circumstances, to look back at ideas from the past, if those might possibly help to get out of a current fix.
Monorails -- moving rather from the "serious" to the "entertainment" front, my favourite monorail, has to be the Listowel & Ballybunion line in Ireland. I wish I had any kind of clue about posting Internet links -- anyway, one can Google "Listowel & Ballybunion monorail", and get to the informative Wikipedia article about this outfit. A steam-worked "monorail" line (with supporting trestles and guide-rails either side of the single central rail) -- everything, including the locomotives, "twin-fashion" either side of the central rail. The whole thing very engaging, but, one has to feel, completely mad. Rather amazingly, this set-up operated from 1888 to 1924 -- might perhaps have lasted even longer, except that the line suffered severe damage in Ireland's "Troubles" in the early 1920s; and that Ireland's new Great Southern Railway -- set up to take over from the beginning of 1925, all railways solely within the Irish Free State -- refused (understandably, but one feels rather unsportingly) to have anything to do with this monorail-type lunacy.
