Moderator note: Split from https://www.railforums.co.uk/threads/hs2-loading-gauge.214161/ They could significantly improve domestic services if they abandoned the illusion that Stratford International will ever see international services and convert the international platforms for full time...

Slightly peculiar topic here, but some work I am doing leads me to consider the Keadby bridge (near Althorpe station) - Officially King George V bridge. Old Bascule raising bridge that was disabled some time in the 50s and converted into a fixed span. Does anyone have any idea how much...

If gas boilers really do get replaced en masse with heat pumps, a lot of people are going to get annoyed if they have 60A service supplies to their houses, as many do!

Mod Note: Posts #1 - #35 originally in this thread. ECP braking is not going to increase operating costs, so any freight flow viable now is viable afterwards. So the cost would be buying up the bankrupt FOCs stock at the auction, fitting it and then the housekeeping of setting up a replacemen...

Mod Note: Posts #1 - #55 originally in this thread. Well one can imagine, with the computing power at our disposal, we could build a model of the entire railway network and then automate timetable generation based on optimisation for various outputs that would be put into the system. Would...

Does anyone know if there is an open-to-the-public way to get a record of just how large the "mainline-registered" rail fleet is? I suppose I could get passenger stock by cycling through the TOCs, but I have no idea how to estimate freight locomotives and "active" freight wagons. (ie. wagons...

Moderator note: Split from https://www.railforums.co.uk/threads/hope-valley-capacity-scheme.168285/ Honestly the railway infrastructure in the entire valley is a mess. Ideally we would rip it all up and start again. Noone would conceive of having three lines up the valley, all slaloming all...

This came up in another thread, so I thought a thread might be interesting. This is technically transport. Essentially a very large part of road/transport traffic these days is associated either with trips shopping, or delivery drivers or one type or another, or people doing rubbish...

Well as you may or may not know, EPS speed limits are differential speeds used by Class 221s and Class 390s when their tilting system is operational. Obviously there are EPS 125 speed limits on the network, but what is the lowest EPS speed limit?

Well, my understanding that underground railway stations must be manned 24 hours a day, for evacuation purposes. But when is an underground station actually underground? If you have a station in an open topped trench, is this underground? What if the trench is covered in a lightweight roof...

Not sure if this should be in this forum or rolling stock. But does anyone know if there is any particular hard reason that tram-trains tend to be built with 100kph / 60mph top speeds? Is there some change to the crash standards above this that makes 70/75 impractical, or is that the European...

Well, I am actually a fan of George Monbiot to a much greater degree than most environmentalists because of his not being anti nuclaer power - and I stumbled across a post on his blog from about ten years ago. http://www.monbiot.com/2006/12/05/life-coaching/ Essentially he refers to the work...

Well we all know that there trains from Manchester to Chester via Altrincham and Stockport. We also all know that these trains are a little hamstrung by a shortage of paths through Stockport, and the rather long way round the trains take. The route does seem to spend a long time going...

So the Greater Manchester Combined Authority has posted notice that an assesment wil be carried out into the practicality of introducing bus franchising in the area. Does anyone know what this might involve and whether there will be any consultations in the near future? Although I doubt much...

As all the long timers in this forum will know, we regularly get threads regarding double decker trains - especially when some politician or other touts them as a solution to capacity problems. The following arguments are often cited against conversion to GC gauge or GB+ to utilise standard...

So every so often it is proposed that the Nottingham tram system would be extended east towards Bingham My normal understanding is that such a system would consist of a relatively short section of tram line that then connects to the Grantham-Nottingham line with the remainder being run as a...

This is a proper Crayonista thread - The objective is to reduce journey times between the country at large and the Nevis Range (the local station being Fort William). The route serving Fort William is currently considerably slower than others that stretch that far north. So if we assume a...

So when did the double post prevention system get disabled? It is a little annoying since I used to just hit the reply key if I wanted to add a quote-reply to an existing post. Now I have to hit several other keys and its taking some getting used to.

Well, for a long time now I have been talking about how advances in the design and performance of power electronics would effect the economics of third rail electrification and now it is time for me to finally write up one of my proposals. This is actually a rather simpler proposal than I...

I am often talking about the advantages of third rail versus 25kV in certain low-power and low-speed scenarios. Where the low capital cost overwhelms the operational savings of 25kV. Now, I want to talk about the other extreme. Extremely high service density routes, especially new construction...
