As I understand it a 3 carriage Cl378 has double the power of a Cl313 of equivalent length and, even accounting for the formers higher weight, therefore must be considerably faster to accelerate than the older unit. As I understand it Cl313s were used on some London Overground routes prior to...

Well it seems that with the construction of the Hitchin-to-Cambridge flyover attached to the Thameslink programme is to be taken in hand relatively soon (assuming work hasn't already started), there is only one major bottleneck remaining on the Southern ECML, that being the two track section...

The Situation Railfreight mostly lost the wagonload market, such as deliveries to shops and so on, to road freight in the 50s and 60s as the cost of transhipment to and from the road vehicles used for the first and last miles was higher than the cost of using a single road based movement over...

Well basically I thought it might nice to assemble a list of specifications taking parts from all existing EMU/DMU families to create a perfect multiple unit train for regional/outer commuter services. Well to start with for the EMU: Class 444 level interiors Improved toilets compared to the...

Well I'm not sure if this is really metro or infrastructure so I will just post it here. Ive always thought that 750V was the maximum feasible voltage for electrified railways running on public streets for various discharge reasons. (double decker bus or artic runs under the wires and causes...

Is there somewhere I can get a comprehensive breakdown by class/type of all the locomotives/passenger units used by all the TOCs and freight operators in the UK? If freight is impossible I would settle for a passenger stock only list.

Well once IEP deployment finally starts, or whatever is going to replace the HSTs on the MML, GWML, ECML and wherever else, the HSTs will be redundant and, considering that they are now approaching 40 years old, likely withdrawn. Im going to assume that the majority of the Mark 3 coaching stock...

Now as I understand it, third rail electrification is only to be used for "infill" or similar work. I assume this is where the changeovers would represent operational difficulties such as requiring the use of dual voltage rigged (and not just capable) stock and requiring stops to change over...

I was into model railways a little when I was a child I keep wondering if I should get back into it and I was wondering if there are any Southern Region Multiple units available around at reasonable prices. Stuff like the 5WES and 4REP and a variety of things like that, things with jumper...

As I understand it, Moorgate Branch is now closed as part of the all-singing all-dancing (and nigh on fifteen years late) Thameslink 2000/Programme. What has happened to the Thameslink platforms, are they still out of use or have they been pressed into service for the other Moorgate commuter...

Well the DfT paid for a study on the technical issues relating to electrification of lightly used mostly-self-contained branch lines using equipment derived from Tram systems, ~750V DC using a mix of variable-tension equipment and trolley style wiring. I obtained the final report from this...

So.... Ive been reading around a bit on the Class 151, and have discovered that the supposed weight of a three car unit was only around 95-100t which seems extremely light, almost pacer light in-fact compared to the apparently ~90 tonnes of a two vehicle Class 171 unit. Is this weight accurate...

I was wondering why it takes 2 hours 15 minutes for a train to transit the Highland Main Line between Perth and Inverness, a distance of approximately 117 miles by the railway line. There also appears to be a 30 mile gap north of Carrbridge and 20 miles between Dalwhinnie and Blair Atholl that...

I was wondering if there was a way to get a train from the platform at London Kings Cross to the Heathrow Airport Station? As far as I can tell, the shortest route is to run the train up to Finsbury Park, reverse onto the North London line and from there onto the Great Western Main Line. Is...

I was just wondering how big the loading guage on the Tyne and Wear metro is. I would assume that since most, if not all, of the tunnels were used by the Tyneside electrics before the opening of the system that it is pretty similar to mainline gauge but I'm not sure if some corners were cut...

Well I'm sure this has been done to death but I checked the first several pages of the forum and can't find anything so here I go. East Coast currently operates 13/14 HST sets over a variety of routes, serving destinations like Lincoln, Aberdeen, Inverness and Hull. They also run diagrams on...

Not sure this is where this would go but oh well I apologise if its not. Well this is my first post on these forums but Ive been reading them for quite some time, seem to have a real cross section of knowledgeable people here. Well, I got thinking about the really insane cost of HS2...
