Transport authority Merseytravel said the amount of passengers using the Liverpool South Parkway interchange in Garston has doubled over the past 12 months.
Merseytravel said over 35,000 passengers a week now use the interchange and this figure is set to increase further, from Sunday 12 December, when TransPennine Trains will stop at the station daily, offering passengers a link to Liverpool John Lennon Airport and onward travel to Crewe, Birmingham, Runcorn, Manchester Oxford Road, Sheffield, Nottingham, Norwich and across the Merseyrail network.
Leo Goodwin, commercial director for First TransPennine Express, said: "With direct trains, quick, frequent bus transfer and a choice of low-cost airlines, we're confident that passengers from across the Pennines will appreciate how easy it is to reach the airport. We'll also be offering discount advance purchase rail fares to complete the package."
The bus and railway station opened in June 2006 providing a better link to Liverpool John Lennon Airport.
The £32m Liverpool South Parkway interchange is praised for its sustainability elements such as a rainwater harvesting system, geo thermal heat pumps, enhanced roof insulation and solar photovoltaic cells on its south facing windows which provide electricity supply to the building.
