Is there any other,  can just see a 44' 3" ramp would work at 125 mph

Just under a quarter second should be enough, shouldn't it?  Grin

Although reading the attached article, the effective length is only 25'8" so 140 milliseconds might be a bit tight!

Appologies for that error, but my excuse is that when I posted the update I was sitting at my desk at home trying to work out some changes to the mechanical interlocking on an hi-tech GWR (Great Western Railway) 1908 pattern lever frame..... Roll Eyes Tongue

ETCS (European Train Control System) Level 0 Huh    If you added ATC (Automatic Train Control) would that make it level 1?

I ask as a baffled E&P Engineer

Yes it would, but it would need to be the GWR version of ATC Grin

Is there any other,  can just see a 44' 3" ramp would work at 125 mph

Interesting document on the GWR ATC here https://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=19&ved=2ahUKEwjV6_iAlbDpAhWbVBUIHcGIACIQFjASegQIBBAB&url=http%3A%2F%2Fwww.rmweb.co.uk%2Fcommunity%2Findex.php%3Fapp%3Dcore%26module%3Dattach%26section%3Dattach%26attach_id%3D953953&usg=AOvVaw1NVyPmiY3fex5c6T9LydM8&cshid=1589349951811925

Yes, it could be done with coded track circuits like the original 1968 Victoria tube line. Level 1 is nothing new.. Grin

750 loudspeakers at places like Taplow may lead to complaints of noise nuisance from nearby housing, might it not?

I've been in one of the Contractors Lab / development area.  It would be complex in its self if it was just one company supply systems but its not.  There are large companies who are normally in cut throat competition with each other have to work collaboratively.

One concern they have (and they are a the UK (United Kingdom) part of Germany company) is the free flow of information and engineers after the 31st Dec 2020, whilst it will not stop progress may be slowed down

Now seems a good time to invite you to look at the Crossrail Learning Legacy programme - if only because it may be taken down soon! WARNING: Please make sure you are not eating anything you might choke on when you look at this.

Quote
About Learning Legacy

Learning Legacy is the collation and dissemination of good, practice, innovation and lessons learned from the Crossrail construction programme aimed at raising the bar in industry and showcasing UK (United Kingdom) PLC.

The Crossrail learning legacy builds on the work previously undertaken on the London 2012 Learning Legacy and contributes to an overall body of knowledge on major construction projects.  It aims to share:

    Knowledge and insight gained during the lifetime of the Programme that may be of benefit to future projects and programmes
    Documents and templates that have been used successfully on the Programme that can be ‘pinched with pride’ by other projects
    Datasets that can inform future research projects
    The experts behind the delivery of the Crossrail Programme
There's much more at that link.

When I first came across this, some time ago, the words "hubris" and "tempting fate" did flicker across my consciousness...

Wel, in fact the Crossrail Learning Legacy programme wasn't tactfully folded up and packed away, but it (or at least its web presence) is still there. Now I find that there is still a public corporation no less (the same status as the BBC» (British Broadcasting Corporation - home page)) called Crossrail International.

OUR MISSION

Our mission is to share the experience of Crossrail’s people and partners in helping cities around the world unlock their potential through the provision of world-class transport networks that enable sustainable growth for their communities.
   
OUR EXPERTISE

We're raising the bar for infrastructure projects around the world by making Crossrail's experts, lessons learned, good practice and innovations available to industry stakeholders.

I bet its employees are rather glad we are not going to parties at the moment - it must be painful having to field those "Crossrail International - what do you do there?" questions.

From The Guardian

Quote
The heavily delayed Crossrail will not open as planned in summer 2021 because of delays caused by coronavirus, its board has said.

The troubled railway, from Berkshire to Essex via central London, was originally expected to open in December 2018 but repeated delays have pushed it back.

On Thursday evening, Crossrail said: “A programme of this scale and complexity was already challenging, the impact of Covid-19 has clearly made the existing pressures more acute.

“Due to a pause of physical activity on sites and significant constraints on ongoing work – time has been lost, only some of which can be recovered.

“The opening of the central section between Paddington and Abbey Wood next summer, as announced earlier this year prior to Covid-19, is not achievable.”

Crossrail did not provide a new date for when the railway line, to be called the Elizabeth line, was now expected to be open, but said that a “more comprehensive update” would be issued in due course.

On this occasion at least a much more plausible reason.
