I snapped this sign at Bradford Interchange today.
In the background is a Grand Central service awaiting departure for London.
According to the Open Access operator you can buy your ticket aboard their trains without penalty.
I wonder who is right?
UPDATE: This from a Mr Ed Chap...
Presumably this is all at the DfT's behest, to make it more difficult for the Open Access operators?
After all, WSMR has gone and I am sure some in Marsham Street would like the rest to disappear as well.
