Network Rail has announced an investment plan of £15 million to upgrade the infrastructure of the East Coast Main Line.

It will also aim to improve the punctuality and performance of trains. A stronger focus is being given to the southern end of the line. It reports that a series of infrastructure failures and engineering problems have had an effect on passengers.

Work will include additional maintenance in the tunnels and renewing track. To reduce risks, Network Rail will also invest in helicopter patrols, inspections via cameras and the removal of vegetation.

Network Rail's route managing director for London North Eastern and East Midlands Phil Verster said: "Network Rail has presented plans to our customers that set out how we intend to reduce signal failures, overhead power supply problems and engineering work overruns that have affected services."

Mr Verster said the organisation hopes to see the benefits of this funding within the next six months.
