Chelney hawks

Proposals for an additional cross-London passenger railway, on the Chelsea – Hackney axis, can be traced back to the first half of the twentieth century, but funding was never forthcoming. In the days of the London Transport Executive, the ‘Chelney‘ line was generally envisaged as a self-contained small profile Underground railway. In the 21st century, the Chelney line has been re-imagined as ‘Crossrail 2’, featuring tunnels large enough for National Rail trains.

Chelney (Chelsea - Hackney) rail route, safeguarded course

Over the last six months, a working group of the “influential” business organisation London First has been looking at the case for Crossrail 2. According to its interim report, detailed planning of a suitable scheme “needs to start now”.

The study, led by former Transport Secretary, Lord Andrew Adonis, has considered work previously undertaken by Transport for London on a route for “Crossrail 2” between Chelsea and Hackney, and examined demand and congestion forecasts post 2020 and the impact of new national projects, including HS2.

Its conclusions are clear -– by the late 2020s, even after the completion of Crossrail, Thameslink and the current Tube upgrades, central, south-west and north-east London’s rail and underground networks will be heavily congested, and there will be a critical need for new capacity. This will be best provided by a second Crossrail line connecting these parts of London.

Around 1.3 million more people and over 750,000 more jobs are expected in London over the next 20 years and as such, planning for the next generation of transport improvements post 2020 must begin now.

The London First report presents some form of heavy rail Crossrail 2 as the one and only solution to providing adequate transport capacity on London’s North East to South West axis. However, it does not specify precisely what points should be served, or whether the railway should be a self-contained (possibly automated) tube line [‘Chelney tube’], or a regional interconnector built to National Rail standards [‘Crossrail 2’].

Crossrail 2, options presented by London First

Whether London First’s hawkish backing of Crossrail 2 is a good fit with the capital’s transport priorities, is open to question. In the central area, there are crowding issues on several Underground lines, which need to be tackled in the next few years (not the timescale of a new heavy rail line). Street tramways offer the possibility of replacing the Underground for short journeys in the centre, and for that role, would have a general time advantage. Using long trams, one way flows of over 10,000 passengers per hour should be feasible.

So there seems to be a good case for building a street-running tramway on the Chelsea – Hackney axis to meet the local transport needs of the next few years. In the longer term, a ‘Chelney Tramlink’ could be complemented by a Crossrail 2 tunnel using the safeguarded route, but built to take National Rail trains. There would be the possibility of connecting Crossrail 2 into the South West London and Eastern Region tracks.
