For pounds 2, passengers arriving at the station can have their bags carried to the train, and those leaving trains can be escorted to taxis, the London Underground or BR's Thameslink service.
Six staff are being employed and will wear distinctive uniforms. The service can be booked in advance.
The old portering service was provided free, although most passengers tipped the porters. 'We don't think the pounds 2 charge is excessive, especially compared to airport baggage services which cost about pounds 5,' a spokesman for InterCity said.
