St. Simon Posted January 15, 2018 Share Posted January 15, 2018 Seriously, water is heavy stuff and where will it go after peope have showered? Could waste shower water be used to flush toilets, therefore halving the water requirement? Simon Link to post Share on other sites More sharing options...
Bon Accord Posted January 15, 2018 Share Posted January 15, 2018 As shower/sink waste water is "grey water" and not "black water" as with sewage, could the regulations be slightly different i.e. permitting shower water to be discharged onto the track?

RMweb Premium newbryford Posted January 15, 2018 RMweb Premium Share Posted January 15, 2018 (edited) Why do they new brake force vehicles? Presumably as loco hauled stock the brakes are standard two pipe air Good question. The original video of them in August in Europe had only one vehicle at each end - presumably as a they are coupling adapters Cheers, Mick Edited January 15, 2018 by newbryford Link to post Share on other sites More sharing options...

jim.snowdon Posted January 15, 2018 Share Posted January 15, 2018 Another part of the modern railway which I hate lack of compatibility between vehicles why the hell do they need delners what's wrong with a droppable buckeye ? Probably because the Dellner/Scharfenberg coupler provides what they want better than anything else, and there is no mandatory requirement for any specific form of drawgear. That isn't a situation peculiar to the UK either - there are, and have been for decades, any number of multiple unit vehicles running around on the railways of the rest of Europe with non-UIC standard couplers. Ultimately, it is down to the railway operator to assess the probability of one train needing to be rescued by another and thus whether there is virtue in mandating a standard form of drawgear. The UIC side buffer and drawhook arrangement is only mandated for stock, passenger and freight, where individual vehicles are routinely interchanged with other standard gauge railways.

Hesperus Posted January 15, 2018 Share Posted January 15, 2018 Another part of the modern railway which I hate lack of compatibility between vehicles why the hell do they need delners what's wrong with a droppable buckeye ? I hate it too but there are a lot more passenger trains than freight, over 90% of those are multiple units of some description virtually none of which use conventional drawgear. Delners are probably more common than buckeyes now so might improve the prospect of recovery. Link to post Share on other sites More sharing options...

Having said that not sure how eurostars do it Is it because Eurostars have a pan up per set, thus providing ETS within the set, so there is no need for inter-set ETS connection? Only the control circuits then need to go through the coupler. Cheers, Mick Link to post Share on other sites More sharing options...

RMweb Premium jjb1970 Posted January 16, 2018 RMweb Premium Share Posted January 16, 2018 I've sometimes wondered about incorporating the power supply into an auto-coupler. If you wanted to do it I see no reason why you couldn't include a power umbilical into the auto-coupler, as electrical loads go the hotel load of a train won't be that high (I'm saying that in the context of industrial electrical loads, not domestic ones). One of the arguments in favour of the bi-mode class 80x trains is that attaching diesel locomotives to drag them off the wires would take too long but I see n reason why a modern high performance diesel locomotive with an auto couple couldn't be attached very quickly and safely with no need for staff to go anywhere near the couplings and connections. After all, EMUs connect and split regularly and it isn't a big issue. On interoperability, I'm not sure it is an issue within the train as they look to be effectively fixed sets, and presumably if the locomotive fails then it will hae a coupling able to be used with a rescue locomotive?

ejstubbs Posted January 16, 2018 Share Posted January 16, 2018 (edited) We should have standardised on Kaydees decades ago, like our former colonies did. Actually, of course, they standardised on Kadees. That's the problem with standardisation: if you're not careful, the standard you thought everyone else had standardised on turns out to be a different standard to the standard you've standardised on. Even with spelling. Edited January 16, 2018 by ejstubbs Link to post Share on other sites More sharing options...

The resulting arc from a coupler if it divided by accident could weld them back together! Having said that not sure how eurostars do it Irrelevant on 373 Eurostar as they are basically two half-sets coupled to each other with independent power supplies and there is no 25kv bus connection as they were not permitted for Channel Tunnel operation when the Eurostars were designed. ( don't know how things are arranged on the Velaros though. Link to post Share on other sites More sharing options...

( don't know how things are arranged on the Velaros though. Velaros are treated as a single unit, not a divisible train- there is a 25kV line from one end to the other, with at least 4 pantographs. ET does use a 1500V train line from loco to loco, with some sort of 'load-shedding' device at halfway. Very occasionally there are problems with water ingress to the coupling head.
