Re: Off the Rails - Train Stuff

Wow! That turbine powered machine has a lot of grunt. It sounds angry too. Impressive stuff. When I was a kid my dad had a yard along the bottom of which runs the main north/south line up to Edinburgh but back then it also hauled a lot of coal and I well remember the whistling of the big Deltic engi...

Re: Off the Rails - Train Stuff

(not “trains” please -a train is the rake of carriages or wagons that a locomotive draws) Oops - sorry guys. Noted. I'm always the first to get upset if someone calls a compressor a turbine or a turbine a 'hotwheel' (which is almost but not quite as bad as calling Christmas 'Crimbo') So Locomotive ...

Re: Off the Rails - Train Stuff

Why was the steam turbine never used in trains, then? It was certainly small enough and more efficient.

Re: Off the Rails - Train Stuff

That's pretty much where marine steam propulsion had got to when it hung up its pistons and connecting rods and swapped them out for the turbine and a pot of fissioning material. Agreed that getting an effective condenser onto a steam train was always going to be a big problem but what's the reason ...

Re: Off the Rails - Train Stuff

Intriguing. I've seen little diddy triple expansion engines in steam tugs and trawlers that would easily fit into a train complete with boiler, condenser the lot. Wonder why they didn't do it that way. Seems like train development stopped and marine stuff carried on.

Re: Off the Rails - Train Stuff

After all that, I suppose I really ought to sign off with as a geek..... :ugeek: Geeks are good - they fit in around here. I guessed it had to be the condensing problem, though the condensers on marine engines can be pretty compact units. That said, they do have a limitless supply of seawater to pu...

Re: Off the Rails - Train Stuff

Okay - question for the steam train enthusiasts. My understanding is that you fill your loco up with coal and water, light a fire and once everything is hot and pressurised away you go. The steam passes through several expansion stages then is blown up the spout to make the fire draw. Is that correc...

Re: The Bloodhound SSC/Thrust/Noble Thread

Been watching that and, yes, impressive stuff, but it looks like taking big bites in a short time frame. Maybe team and vehicle are perfectly up to doing that but I was surprised at the rate at which they are upping the speeds. Also, did anyone see that a piece of titanium panel was peeling away eve...

Re: Planning Time before the Proving Trial?

All quiet, l'm afraid. Looks like no running next year, unfortunately.

Re: Off the Rails - Train Stuff

I watched some guys milling flour using a water wheel a few months back. There'll always be some nutter who wants to mess with old machinery no matter what it is.
