Around half a kilometre of track dating back to the 1950s will be replaced near Northwich in a £700,000 Great North Rail Project investment.
The section of railway acts as a bypass for freight trains – meaning journeys for passenger services operating between Chester and Manchester Piccadilly will be faster and more reliable.
The upgrade will ensure fewer delays for passengers and will make the movement of freight across the North and South of the country easier.
Between 29 and 30 June, 530 metres of worn-out wooden sleepers will be replaced by modern concrete ones.
The new rail will be continuously welded – a technique which makes it stronger and better able to cope with heavy freight trains weighing up to 2,500 tonnes.
Tom Hugill, asset engineer at Network Rail, said: “Northwich loop’s £700,000 Great North Rail Project makeover allows the safe movement of freight and passenger trains essential to the Northern Powerhouse to continue across the Pennines and down to the South. This not only eases congestion on our roads, but also helps the environment as each freight train takes 76 lorries off the road.
“This upgrade also means less maintenance costs for the railway in the long-run, as the more modern and robust track can better carry the heavy loadings of the eight freight trains that pass through each weekday.”
There will be no disruption to passengers while the work takes place.
Each freight train takes 76 lorries off local roads and every tonne of freight carried by rail cuts carbon emissions by 76%.
