The station at EGCC is, unfortunately, situated at the end of a 'siding'.
Indeed, it is an another example of doing things on the cheap without looking at the long term view.
However with the use of multiple units it is not a major issue. The driver can walk from one end to the other in a couple of minutes.
If the waist of money that is HS2 does ever materialize hopefully they will enable inter regional trains to also use it between Crewe and Manchester airport and also provide a connection from the Chester line into the airport at the same time.
