A vehicle / load shouldn't exceed 5.03m (16'5) from the roadway this is minimum clearance above which a bridge doesn't need have its height indicated by way of a signage. All motorway or trunk road bridges should have at least 5.1m clearance. There is technically no limitation on the width...

Previous transitions rarely had the timetable and stock changes happen simultaneously there would be a lag between introduction of new stock and then timetable changes to take advantage of the stock. I expect in a couple years once the new stock has bedded in and the staff re-training process...

The press release Hitachi rail put out highlights that as part of the streamlining they're investing in adding both welding and painting facilities. TBH I expect the EMR, WC and First Scotland orders will have the bodyshells produced at Newton Aycliffe rather than Kasado.

The Berkeley report puts HS2 (complete, so inc phase 2) at £106bn, then highlights to deliver all benefits regional upgrades are also needed to tune of £43bn for connections and local service upgrades at £39bn so a total of £187bn for HS2 + everything recommended. His alternative is actually not...

The permanent lock out introduced by the specification for version 3.27.x appears have been intended to cover situations where resetting without diagnosis could result in damage to the train which would then have been a problem from Siemens to fix. The lock out in event of transient low power...

The reduction in power should/would translate into a reduction in fuel consumption, but may not see an improvement in efficiency indeed at less 100% load the efficiency may and likely will actually reduce, this is in part dependant on what the targeted power output was at design stage. Diesel...

I suspect the thinking is/was to avoid the traditional cavern station and form the platforms along an oversized tunnel bore, but yes it still requires a massive subterranean station relative to other stations. I'd assume this would have to be a very deep level station to avoid the Thames and...

The US has moved to chip and nothing 'cause pin pads was to bigger cost / complexity to rollout. The cards as issued are technically of the EMV (chip & pin) type just with the pin function not used. Contactless tap-in just isn't going to happen for long distance jouneys as the CC issuers and...

Cummins claim a consumption of 215 g/kWh at 100% rated load whilst MTU a few years ago published a number of 196 g/kWh @660kw (885bhp). Converting these to l/h results in 215 x 560 / 1000 / 0.85 = 141l/h vs 196 x 660 / 1000 / 0.85 = 152l/h. Overall consumption of the MTU 1600 series is obviously...

The 2010 options where all for a terminating not through station, which necessitated formation of a cavern. All these options appear to have been sifted out on the basis of size and complexity of cavern needed noting it to be the equivalent of four crossrail stations together. The CCC option...

I'd have thought that the first class driving unit would still have a mini food service area to both store trolley stock and allow the first class complimentary service to be operated. I'd expect the actual service to be trolley based either mobile or on the busiest static from the trolley base.

Plane is only an alternative for Exeter to London City around 160 seats daily during the week in each direction, in comparison to the daily number of seats GWR yes it is a tiny alternative and probably no quicker than train. Generally paid for food service is not profitable for an operator, so...

Personally I can see the entire 22x fleet ending up with XC with a minor interior refresh to match the HST's and the fleet intended to see life into early 2030's then replacement probably by a new train type or a further evolution of the 80x family. EMR will I suspect place a follow on order for...

The microwave gristle cheese burger certainly continued past BR into the Great Western, First Great Western and then First Greater Western era's, IIRC it must have been around '08 to '10 that it died to be limited only to the then travelling chef services, which suffered immensely from crew...

The problem with ITSO is project started from the wrong point that of the ticket being loaded and stored on the card/token replicating the functionality of paper tickets, which is understandable considering connectivity and cost thereof when the project started. So whilst in theory a ITSO card...

Laira isn't currently a maintenance base for Hitachi only light servicing so using five cars to replace the short HST sets would still require the diagramming to send the units back to Stoke Gifford (or North Pole). Maliphant is also only a light servicing base so any Wales to West Country...

I've have thought the PE tickets would be sold as some form of standard class ticket to get around corporate restrictions on first class booking, the question being will a PE standard have any flexibility or be a fixed time AP? The former being far more attractive to business travellers. One...

I'm going to guess there is a sightlines issue when in close proximity to a train with another sculpted nose that makes judging distance ahead difficult if not impossible resulting drivers effectively driving "blind" as to how near or far they are?

As an alternative assuming not London but far enough away for a sleeper to make sense and large market then maybe Birmingham? could be timed to connect with XC and VT day trains for onward travel and originating travel and the Jacobite..

Railnet effectively existed in two versions the original planned and delivered version and then the never implemented post 2001 limited version. Railnet v1 between 1996 and 2001 served Shieldmuir, Low Fell, Doncaster, Warrington, Stafford, Bristol, Willesden, Tonbridge. Services also operated to...
