If risk is transferred to the private sector, the contractor guesses their risk exposure and prices it in, and possibly hedges some of it. In this case, I'd imagine all of tier-1 contractors would not have hedged enough for the combined effect of inflation, the Ukrainian war and Brexit and be...

I'm doubtful that any member of the government is going to be keen to do that photoshoot - or be particularly welcome on site if they did.

FPK has seen a few improvements over the last few years, but none of these were holistic solutions to the ills of the station. There are now lifts to all platforms, and part of the original concourse has opened as a tunnel at street level. The lack of gates previously made it an attractive...

It kind of is - particularly Essex Road and Old Street stations (Moorgate got retiled a few years back). Just not the type of heritage anyone is clamouring to keep.

It seems that the standard CLASP system had timber roof and floor decks up to Mk4 of the system, and Mk5 (from late 70's onwards) used pre-cast concrete panels. The floor and roof decks bolted together and to the frame to form a diaphragm, forming an intrinsic part of the structural integrity...

From the Guardian Article, we note that NIMBYs are out in force. “We have been predicting that something like this would happen for the last 10 years,” Jennings said. “We have been giving a consistent message to HS2: ‘Don’t tunnel through chalk, it’s unstable.” Is chalk inherently less stable...

With an Absorption chiller. These are common enough in co-generation plants (in large buildings, particularly hospitals). They can use low-grade waste heat to drive a cooling cycle. Both steam and diesel locomotives have plenty of waste heat that would otherwise get vented to the atmosphere.

London's Temple of Mithras is right next to the Bank station entrance on Walbrook

Making the a shaft a third bigger to accommodate a fourth escalate increases the volume needing to be excavated by a little more than 1.75 times. Building another escalator shaft - at twice the volume - now looks attractive as it can hold another three escalators. 1669248461

Indeed, but there are people out there - such as Chris Packham, willing to clutch at more straws than an onanising scarecrow. They'll no doubt continue until the project is complete. It will be fascinating to see whether they make use of the new services. If the government is serious about...

SSP.... Eggs and baskets spring to mind. Perhaps not the winning business model it once was.

it surely depends on the geology the tunnel passes though. In London is either clay or chalk, which is fairly soft. The Pennines might be a different matter.

Did they get the RMT union to provide the 'balancing' viewpoint as the BBC aways does?

"At a time of rising fares and growing passenger dissatisfaction, an investigation has revealed that thousands of unused trains are standing idle in rail sidings and depots across the country. According to industry experts, the unused “ghost trains” worth at least £3bn and containing over...

This speaks volumes about your employer rather than anything else.
