Christ. At this rate we might even get taken over before this bloody opens!

Absolute tossers!!  I'll be bloody retired before they open it and won't need an 8 minute journey home from work!!  ;-/

After crossrail, which im not getting into the politics, just agree it is a huge huge engineering project that will benefit many people, i hope they can get around to upgrading local stations. Still cant believe so many stations dont have lifts still in 2019

You say that like it's not some huge engineering job!

Some tube stations are 100 years old and very deep underground!

Sorry i meant train stations lol

How hard can it be to dig a lift size hole?

I see some stations with no lifts or even a ramp still? 

Take Petts Wood for an example.  From the Daylight side, its two flights up, two flights down to any platform.  From the Sovereign side, its one flight up, two down.  Was turned down for funding for step free access not so long ago.  Disgraceful really.

On the plus side, no barriers!

TfL have this morning revealed that Crossrail has been delayed yet further until autumn 2021. The previous hope was early 2021 though this is hardly a surprise given recent progress.

The delay is mainly due to signalling issues. Most stations are now complete or almost ready.

Railway signalling must have got really really difficult in the last 5 years.  There's permanent trouble all around Lewisham, according to southeastern; Branson had recurring issues all up the WCML for years; now Crossrail can't build em right from scratch on almost entirely new trackways.
Either that or all those cash guzzling frauds reckon that's the sort of plausible sounding bullshit they can trot out to mislead the gullible gravy train suckers at DoT and fob off us poor saps who have to fund the whole farago and use the runt of a so called service that's left.

I seem to recall it's not the signalling on the Crossrail track that is a problem.  Crossrail also uses or crosses non-Crossrail track and it is the integration of the various signalling and train control systems that is the issue along with very limited testing time each night.

On a positive note. Soon they won't be able to refer to it as Europe's biggest project (Unless they go by Continent of course) :-)

Pretty much, different signalling system on the line between Paddinton and Reading, a different one to Heathrow, and a different one up to Shenfield, the systems all need to talk to each other, and a train from say Abbey Wood to Heathrow, would need to be able to communicate with three different systems to complete its journey and keep passengers safe. 

The on board train software needs to translate the 3 different signal systems instantaneously as the train moves through the system which is part of the problem. Bearing in mind the timing of the service it is very difficult to run this train service with the driver in control.

Surely it is by continent - it was not referred as EU's biggest project.

Interesting to find out how it compares with Paris and their Grand Express project for new metro lines.
