The present station is very poorly sited. At peak times one can be stuck in traffic for 20-30 minutes just to travel the last two miles to the station when approaching west from Nantwich. I believe there is a similar problem when approaching from the east also, although this has been slightly alleviated by the opening of a second station entrance and car park. Moving the station to the A500 dual carriageway would be ideal, providing a quick and easy connection to the M6 and ample space for park and ride facilities. According to NRE Warrington Bank Quay car park costs £4/day. What makes you think that a park and ride car park at Crewe would cost more than £8/day (the current daily charge at Crewe)? If the charge was lowered to £4/day, it would be close to the £3.50/day currently charged by Cheshire East Council for use of its two car parks near Crewe station.
Although the A500 is not within walking or (perhaps) cycling distance of Crewe town centre, there is always the possibility of opening an additional small station somewhere between Crewe and Chester, such as next to the Crewe Heritage Centre / Tesco, or next to Morrisons on Vernon Way. Therefore there would be a two-platform 'Crewe town' station to serve the town centre and a larger 'Crewe parkway' station to serve everyone else. Somewhat like Bache station (located behind a Morrisons in a large residential area of north Chester) and Chester station, even though the latter doesn't come close to being a 'parkway' station.
