Gatelines are a right pain because you can't get through the normal

Not if they use the same style of wide gate that is installed at Chiltern
stations. They are operated by ticket, the same as the normal gates. They
have different style of paddle fitted, rather than the large flat panel they
have a tubular construction in place.
