The London Assembly has been told that construction work at Hayes & Southall stations may not be finished until next year. From BuildingConstruction work is being carried out at six stations between Acton Main Line and West Drayton and is due to be finished by the end of this year.
Hochtief won a £40m contract to upgrade Hayes & Harlington, West Drayton and Southall stations last January, while Graham was handed a £47m for similar work at Acton, West Ealing and Ealing Broadway stations.
But a letter from Network Rail chief executive Andrew Haines to London Assembly transport committee chair Navin Shah admitted work at two of Hochtief’s stations is in danger of falling behind.
Haines said: "There is a risk that the works at Hayes & Harlington and Southall stations will not be complete until the first quarter of 2021 but we are working with our contractors to minimise any potential delay." |

Seems to be some through train testing today (Sunday 15/03/2020) between Acton Main Line and Paddington Crossrail platforms.

Indeed, the TfL» Rail service has been amended as a result - I saw a poster a couple of weeks ago about it, so planned well in advance: TfL Rail: Sunday 15 March, no trains between Paddington and Ealing Broadway. There will be a reduced service between Ealing Broadway and Hayes & Harlington with trains running every 15 minutes. |

and further ... from myLondonThe construction of Crossrail has been temporarily suspended in response to the government announcing a lockdown.
The project, which began in 2009, is a 73-mile new railway line stretching from Shenfield in Essex to Reading, Berkshire.
The decision to suspend the building of the line is due to the risk workers face catching and/or passing on the deadly illness, Covid-19.
On Monday evening (March 23), Prime Minister Boris Johnson made the announcement that citizens' movements will be severely restricted over the next three weeks due to the rapid spread of coronavirus.
Despite Johnson not specifically mentioning construction workers, a debate has been raging since the lockdown announcement on whether construction workers should be staying at home.
Sadiq Khan, the London Mayor has prioritised making the London Underground available for key workers at hospitals and in social services.
Mike Brown, London's Transport Commissioner, said: "The Government and the Mayor have given clear instructions to stay safe and to stop travelling in all cases other than critical workers making absolutely essential journeys.
"In line with this, TfL» and Crossrail will be bringing all project sites to a temporary Safe Stop unless they need to continue for operational safety reasons. |

ETCS▸ Testing successfully completed. From Railway Gazette: https://www.railwaygazette.com/uk/etcs-tested-successfully-on-heathrow-express-class-387s/56178.articleHowever, there are apparently still some issues to resolve with the TPWS▸ Interface...... ETCS tested successfully on Heathrow Express Class 387s
An initial series of test runs using Class 387 EMUs▸ equipped with ETCS on the Great Western Main Line has been completed, leasing company Porterbrook announced on April 3.
Using sections of the GWML▸ east of Reading and the branch from Hayes & Harlington to Heathrow Airport, the tests were undertaken by Porterbrook and partners Bombardier, the Department for Transport, DB» Cargo UK▸ and Heathrow Airport Ltd. More than 10 test runs over the weekend of March 21-22 were undertaken to prove the functionality of the onboard hardware and software as well as related infrastructure assets.
A dedicated fleet of 12 four-car Class 387 EMUs is to be redeployed by operator Great Western Railway from Thames Valley commuter services to the airport shuttle. The trains are currently being refurbished by manufacturer Bombardier at its Ilford depot, where they are receiving bespoke interiors tailored to the needs of airport passengers.
Once ETCS Level 2 has been commissioned on the branch between Hayes & Harlington and the airport, expected later this year, the Class 387s will replace the Class 332 trainsets which have been used since the inception of Heathrow Express in 1998.
The Heathrow Express service is owned and managed by Heathrow Airport Ltd and is not part of the national franchising system. However, the airport company has outsourced train operations to GWR▸ under a management contract running from 2018 to 2028. The Class 387 fleet will be maintained by GWR at its Reading depot.
‘Notwithstanding these challenging times, we need to continue focusing on delivering key projects so that the railway is ready to support UK plc when the current situation stabilises’, said Mary Grant, Chief Executive of Porterbrook. ‘Introduction of an ETCS-fitted fleet on services to Heathrow is just such a project and will enable a service uplift to meet expected passenger numbers when the airport returns to its role as a key European aviation hub.’

I assume, dangerously for an E&P Engineer  Level 3 is initially for the Crossrail tunnel sections? |

Thank you. As a retired hotelier and computer programmer, I struggle to understand any of it. However, I note odd gems in an ore of incomprehensibility. |

I assume, dangerously for an E&P Engineer Level 3 is initially for the Crossrail tunnel sections? the TfL» core infrastructure actually uses a different Communications-based train control ( CBTC▸ ) system, either because they didn’t expect ETCS to have reached the necessary functionality before Crossrail commissioning started, or IMHO▸ they decided to have a permanent obstacle to attempts to run other trains through the tunnels. I believe they had to jump through quite a few hoops to avoid ETCS in their core section, being a new railway and in scope of The Technical Specifications for Interoperability (TSIs).

I see it actually refers to ETCS Levels 0,1 and 2 though? Somewhere in the depths of the document it says Level 3 is not included. (Is that full physical removal of lineside train detection and signals?) Paul |

I should have said Levels 0, 1 and 2 which will be utilised on the shared railway sections. As I understand it either Level 2 or 3 will be used on the Core Section not used by other trains (well, not for a very long time at least). The different Levels are explained here: https://en.m.wikipedia.org/wiki/European_Train_Control_SystemAppologies 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.....   |

Level 0  If you added ATC▸ would that make it level 1? I ask as a baffled E&P Engineer |
