Crossrail 'could be delayed until 2021'
Discussion
Does anyone know what the story behind the latest Crossrail delay is?
Surely the hardest part of the project ought to have been building it, not figuring out how to get a signalling system working?

As some who's just left working on a major infrastructure project (Thames Tideway Tunnel - £4 billion, so a similar size to CR), working on the software that controls the tunnel, this delay comes as no surprise to me.
Where were you East, Central or West?snuffy said:

Where were you East, Central or West?It’s funny that a passenger tunnel is always big news but one that is for rainwater and sewage doesn’t get such big attention.

As a Signalling Engineer, trust me, it's a lot more difficult than you might think.Surely the hardest part of the project ought to have been building it, not figuring out how to get a signalling system working?

I’d never heard about this, looks like an interesting project.

Indeed. It's a massive project that no one has heard of, and certainly no one outside of London.It’s funny that a passenger tunnel is always big news but one that is for rainwater and sewage doesn’t get such big attention.
There's been a BBC2 documentary on it. They called it "The super sewer". We called it "The Turd Tunnel" and "The big concrete s

When was the last time the UK delivered a big infrastructure project on time and within the initial budget?
Depends on the definition of 'on-time' and 'budget'.There's the one that all the contractors and project teams know is likely and achievable.
And there's the one that is announced to the public by politicians keen to get votes.
The former is delivered more often than the latter.

Considering crossrail we be used for decades if not centuries does it matter if its a bit late? London relies on the tube network does anyone recall if it was built on time and on budget?
Infrastructure tends to be late and over budget but we forget about that in the long run. It's not as if it ever turns out to be a white elephant. The only under used bit of infrastructure I can think of is possibly the Humber bridge.
Actually thinking about expensive and useless infrastructure, there's also the Olympic Stadium. Can't think why we'd ever need a huge athletics stadium again and West Ham could build their own ground.
Do people use the Edinburgh Trams?

I asked this last time. The answer was heathrow terminal 5.
Of course, the little bit about the entire baggage system not working properly for a little while afterwards was embarrassing. Though ultimately less serious than if the signals that control the trains on Crossrail don't work properly.. GTO-3R said:

People do use the Edinburgh Trams but for me that still doesn't justify the shambolic way in which the project was handled, or the £300 million that Edinburgh council tax payers will have to repay over the next 30 years (in addition to the £550 million spent by central government). Instead of a tram network costing £350 million, we ended up with 1/3rd of the original scheme for three times the cost.....! The single route they ended up with made the least sense in terms of future growth, combined with the fact that two train lines already run either side of Edinburgh Airport and could easily have been adapted to serve the airport.Edited by Fittster on Thursday 18th April 12:01
I agree that given the massive positive impact of Crossrail, a few extra months will soon be forgotten.

AIUI the enquiry into the tram fiasco is still to report.I agree that given the massive positive impact of Crossrail, a few extra months will soon be forgotten.
However, having experienced the construction on our doorstep, it appeared that the work required to discover, identify and reroute the services under the tram route was massively underestimated.
None of which came as a great surprise, given the entirely haphazard systems that have been and continue to be in place for utility street work.
