Indeed, I have heard bilingual announcements made by on train crew on the Cambrian Coast line, but nowhere else. Quite a nice touch really. I’m also not bothered by ‘Transport for Wales’ being mentioned at the English stations they operate. The vast majority of services at Chester go to/from Wales some point in the journey anyway.
Incorrect.
In a normal 4 hour period at Chester:
Birmingham to Holyhead - 2
Chester to Wrexham - 4
Llandudno to Manchester - 4
Chester to Crewe - 4
Chester to Liverpool - 16
North Wales to London - 1
Chester to London - 3
Holyhead to Cardiff - 2
Chester to Manchester - 4
English only services - 27, England to Wales services - 13
Less than a third of trains serving Chester also serve Wales and the proportion will drop further when Chester to Leeds and Chester-Runcorn-Liverpool services get added to the timetable in the next year or so.
