Does anyone else have problems with the barriers to/from the mainline

rejected with a 'Seek Assistance' message (which is easily resolved by
putting through the wide-aisle gate to revalidate it). This is not peculiar
to my current Gold Card as it happened with my previous ticket and with the
replacement that was issued once that one had become worn.

It does seem to be a peculiar "feature" of the gate line at Marylebone,
in that a ticket issued at Marylebone will quite happily work in any of
the gates, but one issued elsewhere (even another Chiltern station) will
sometimes only work in either the old gates (by the end of Platforms 1
and 2) or the wide gates.

And I think it's fairly safe to say that keeping a magstripe ticket next
to an Oyster and/or mobile phone does *not* affect it, as I do just that
and it generally lasts at least three months before needing replacement.
