Cold weather, The first train of the day from Southport (05:37 to Hunts Cross) will only be in passenger service from Sandhills onwards.
Temperatures are expected to fall to freezing overnight and the Met office has issued a yellow weather warning across the North West of England, meaning preventative measures have been activated to deal with the potential for disruptive ice on the tracks.
Cold weather mitigation plans are set to be repeated for a second night on the Merseyrail network as cold temperatures remain across the region from Tuesday 17 January into Wednesday 18 January.
The first night of cold weather, Monday 16 January, saw mitigation plans triggered resulting in a good and reliable service for most commuters on Tuesday morning.
As temperatures remain below freezing and following another yellow weather warning by the met office, Merseyrail will once again take steps to protect commuter services on Wednesday morning.
Tracks on the 75-mile Merseyrail network will be treated overnight to protect them from ice build-up, while station staff will ensure that platforms and car parks are well gritted, so they are safe for passengers.
The plan also means that the first services of the day on each line will run without passengers. Ice on the third rail can cause trains to become stranded so some first trains of the day will run empty to ensure routes are cleared.
Passengers are being advised to check the latest updates before they travel on Wednesday morning.
The following changes will be in place from the start of service;
Chester and Ellesmere Port lines: The first train of the day from Hooton (05:39 to Liverpool Central) will be cancelled.
