Yes, your comments about the committees may well be true and the meaning clear, but it was pure speculation about those being reasons for new 3rd rail being prohibited. I think we've established now that there is no legislation prohibiting the laying of new 3rd rail. However, there may, as...

To be honest, I don't know if they use auto-reclosers on 3rd rail lines these days .... it was always a manual reset back in the old days .... a manual reset was simply "pushing a button", nothing major .... 25kv AC allows more trains to draw more power than can be done via ~750v DC ...

This shows you have a very clear lack of understanding of railways .... Train crew are trained for evacuation of trains in emergencies (and evacuation will only be done in an emergency, not because of a "failed train") .... there are Rules and Regulations that cover detraining of passengers...

that's speculation, not fact the DLR uses "covered" 3rd rail ... some 3rd rail systems around the world use side or bottom contact not for "safety", but because ice forms on the top surface of 3rd rails in the winter ... ice is not a good conductor of electricity so shoe gear can ride on...

No. It's like I said in the first post, people keep saying it's prohibited / illegal etc and I was just trying to find out if it really is prohibited, or if it's a case of people on various forums talking utter nonsense. It seems the latter is true.

The point of safety cases is to identify and manage risks, not simply to choose one commonly-used system over another. So long as all risks have been identified and proper procedures are put in place to reduce risks and manage risks, there shouldn't be a problem. And this is going off-topic...

All railway operations, volunteer or professional, steam, diesel, electric, horse or whatever, need a "safety case": a full assessment of all risks and how to mitigate and manage those risks. It has to be done regardless of whether a 3rd rail exists or not. Likewise, volunteers and staff need to...

The quotes I gave "suggest" it's illegal. The same things appear on various forums. Always suggestions that it's "prohibited" for "safety" reasons, but never any reference to any legislation, nor any reference to safety reports - nothing, zilch, nada, nowt.

Discussion on various forums includes comments similar to those I posted in the first post: there are "suggestions" that it's "prohibited" due to "safety", yet nobody ever references any real legislation. (And that is why I'm asking if there is any real legislation!) I did find this...

I've read several times on this forum and elsewhere, that there is legislation that prohibits laying of any more 3rd rail (except maybe as "infill") and often citing "safety" as the reason. Several people posted to this effect in the thread about Overground at...
