Re: 20,000 Leagues Under The Sea - The Diving Thread

Nice. But how much does it weigh when you’re out of the water?

Re: Off the Rails - Train Stuff

Sadly I have no idea as I was mostly concerned with how to internally blast an inch diameter pipe for the first five or six inches of its length so the swageing tool could be re-used without collecting an uneven layer of soot and thus applying uneven pressure around the pipe's inner circumference. ...

Re: Off the Rails - Train Stuff

.....what caught my interest is that the text says that the back of Leinster Gardens was a good place for the underground steam locomotives to 'blow off' because they were fitted with condensers and had to do this periodically. Any of you railway buffs know about this? Having given this some more t...

Re: Off the Rails - Train Stuff

The early Metropolitan Railway locomotives were fitted with valves which enabled the footplate crew to switch from condensing to non-condensing mode and I would imagine that the opportunity to revive the fire by doing this was welcomed by the crews. So condensers were used on railway steam engines ...

Re: Off the Rails - Train Stuff

As a bit of a Conan Doyle fan I was re-watching the BBC Sherlock series last week and decided to Google the fake houses at Leinster Gardens in London as it featured in one of the episodes. http://www.urban75.org/london/leinster.html But what caught my interest is that the text says that the back of...

Re: Off the Rails - Train Stuff

So, moving on from there, and accepting that making condensers work on locomotives is problematic, I still wonder why no one spannered a turbine in there then simply threw away the steam as with the standard reciprocating machinery of the day. They did: the LMS “Turbomotive” used a non-condensing t...

Re: Off the Rails - Train Stuff

Why was the steam turbine never used in trains, then? It was certainly small enough and more efficient. The steam turbine was in fact often experimented with in railway locomotives (not “trains” please -a train is the rake of carriages or wagons that a locomotive draws). Issues of cost, complexity ...

Re: Off the Rails - Train Stuff

Seems like train development stopped and marine stuff carried on. No, steam locomotive development never stopped; just about everything that could have been tried to improve performance and efficiency has been tried at some stage with varying degrees of success. In the end though, it all boils down...
