[27][28][29] In 2009, concerns were raised and an archeological report issued in connection with a Network Rail application to the National Grid for a boost to the power supply for the WCML at Weaver Junction.
It involved running an underground cable from the grid feeder at Frodsham to Weaver Junction.
On 2 March 2020 a landslip occurred at Weaver Junction partially closing the WCML and required the use of rail replacement buses.
