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 1908 pattern lever frame..... Roll Eyes Tongue

ETCS Level 0 Huh    If you added ATC 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

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!

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

No, it reads almost the same as January's update.

I picked out this snippet:

Each Elizabeth line station has over 50 km of communications cabling, 200 CCTV cameras, 66 information displays, 200 radio antennas, 750 loudspeakers and 50 help points. All this technology needs to be fully installed, tested and integrated.

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 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
