The entrance to the tunnels isn't where the interference of happening. The tunnels start at Liverpool Street

What's a bit strange is that they've been running the same trains with passengers on from Liverpool Street through Stratford for more than 2 years, with passengers, as TFL rail. But I guess they had to upgrade the signalling around Stratford to work with the trains coming through the core, and that is still buggy

The entrance portal is at Pudding Lane:

From there the train will travel underground to the Liverpool St - Moorgate station.

There’ll still be Elizabeth line trains travelling into Liverpool St station but there’ll be terminating.

Fun fact there’s the large ABBA venue going up at Pudding Mill Lane.

The things one misses when not commuting.

No one has called it the ABBAtoir yet, but I’m waiting to see who’ll be the first to come up with that name.

I think you mean Pudding Mill Lane?

Pudding Lane was where the Great Fire of London started.

The tunnels do actually start immediately to the west of Stratford station, around Pudding Mill Lane. The new line follows a different route from the existing main line into Liverpool Street - meeting up with the other branch in Stepney and then via the new station at Whitechapel. When trains start travelling through to Paddington they will take this route.

This means that the boundary between the mainline signalling and the new CBTC signalling in the core is at Stratford. But this only applies to trains taking the new route; services on the existing GEML/Shenfield Electric lines continue to use mainline AWS/TPWS signalling, which is why there hasn’t been any impact on services to date.

You're right. I should have realised it couldn't follow the same line, because I knew about the new stop at Whitechapel.

The current service is to Liverpool Street high level, staying on one signalling communication system. The problem is about changing to a different one for the core (which includes Whitechapel before Liv St). They had a similar problem on the other side but it was resolved easier.

Only the self-contained Paddington to Abbey Wood core section will be part of the initial opening.

Trains from Stratford will still be terminating at the same high-level platforms at Liverpool Street. Through running into the core tunnels (and thus a signalling system change) will come later.

it's quite amusing to hear Liverpool Street's mainline railway station described as high level when it's buried 30ft underground

it was originally buried so that it could connect up with the Metropolitan Railway (today's metropolitian line on the London Underground)

this was so that in 1875 the Met could use the mainline railway station as terminus (whilst their own was under construction)

The low level is buried 34m underground. https://www.crossrail.co.uk/route/stations/liverpool-street/
