The project currently remains on time and within budget, with completion reaching 85%. It is expected that the costs will stay within the £14.8 billion budget, however the Department of Transport and Transport for London will continue to meet with Crossrail Ltd to ensure that the project is being effectively managed, and also looking at cost efficiency measures up to the completion date, to ensure the project is finished on time and within budget.
With the project at 85% completion, it was also announced that the central tunnel station infrastructure is finished, with architectural finishes being applied and lifts and escalators being installed. Track installation stands at 90% complete, and the first Elizabeth Line trains are in service on the Shenfield to Liverpool Street section. More will follow shortly, and staff continue to be trained and familiarised with the trains and routes. Testing will start on the central infrastructure and systems by the end of this year and the central stations will be completely finished during 2018.
The Elizabeth Line will increase the rail capacity in Central London by 10% once fully operational, helping Transport for London keep pace with the growing population of the capital. With 40 stations and up to 24 trains each way per hour at peak times, this massive project is due to be fully completed in December 2018.
