Steve Rotheram admitted Merseyrail's service "fell below standard" in a frustrating morning of delays and cancellations.
The Metro Mayor told the ECHO he "knows how frustrating it is" after large parts of the network were disrupted by the overnight bad weather. Merseyrail warned the forecasted drop in temperatures overnight would mean the first services of the day on each line would run without passengers.
But the cold snap resulted in major disruption on several lines, most notably on the Northern Line where all services between Liverpool Central and Hunts Cross were suspended. To add to passengers' frustrations, a message from the operator told passengers that ice on the roads meant rail replacement buses were unable to serve its stations.
