This would enable us to keep services running safely and reliably, modernise ageing trains, bridges, signalling and track, reduce carbon emissions and improve air quality. But even more pressing is the need to finalise the financial deal with Government so that we can complete Crossrail and open the Elizabeth line. The transformational railway will slash journey times, create much-needed capacity, protect social distancing, transform accessibility and provide a huge economic boost. It would be the ultimate symbol of London’s emergence from Covid — a glittering sign of hope for the future.
