Faster direct links to cities and towns across the north of England are coming – we're electrifying one of the north west's busiest routes to allow faster trains with more space for passengers
This is part of a wider investment to electrify around 300km of the rail network in the area, improving travel between Manchester, Liverpool, Preston, Blackpool, Leeds and York, which is vital to support the region's long-term economic growth.
To make room for overhead power lines, we have reconstructed Farnworth Tunnel. On Monday 14 December a full timetable on the route was restored, with two new tracks now running through the new tunnel.
Once the electrification work is complete, electric trains will be able to run between Manchester and Preston, providing more capacity and quicker direct links between cities and towns across the north of England. Electric trains are greener, quieter and more reliable too.
Farnworth, Moses Gate, Kearsley and Clifton railway stations are now reopened.
We started work on site in March 2015. Fillie, our giant tunnelling machine exited the tunnel at Farnworth in October 2015.
Over the course of the project we:
Around 120 people are working on the project 24/7. We will have worked around 580,000 man hours by the time we finish the project.
In September, we announced that work on Farnworth Tunnel was to be extended beyond the original completion date of Sunday 4 October. The reason for this was due to exceptionally poor ground conditions and unforeseen running sands which the machine had come across during boring. This slowed the excavation speed and created voids which needed filling before boring could safely continue.
Despite more than 1,500 test holes being drilled to try and predict the ground conditions in the area, engineers encountered far more sand than was predicted, making the tunnel boring process extremely slow adding weeks to the programme. It proved impossible to safely excavate while concurrently installing and grouting sections of tunnel wall as was originally planned.
We first hit an area of loose sand on 14 August when our engineers saw it suddenly pouring into the tunnel. This slowed progress and created big voids, the largest of which needed filling with around 35 tonnes of grout. Again on August 27, sand poured into the excavated area and our engineers had to remove 100 tonnes of material by hand.

As part of our railway upgrade plan, we're electrifying the route between Manchester and Preston via Bolton.
We're improving the railway at Chorley station to get the track and platforms ready for faster electric trains.
