English passenger looks at the CIS : 1238 MAESTEG
Him: "Where does this train go?"
Me: "Maesteg, via Cardiff and Shrewsbury."
Him: "I want to go to Chester."
Me: "Yep, this one will get you there. It goes through Chester on the way."
Him: "Then why doesn't it say Chester?"
Me: "Because it doesn't end up at Chester, it only calls there on the way to Maesteg."
Him: "That's confusing. So where's this Moyes-tig place then?"
Me: "South Wales, north of Bridgend. This train reaches Cardiff just in time for the evening rush, so it carries on through as a commuter wagon."
Him: "Why don't you use the English word for it?"
Me: "There is no English word for Maesteg."
Him: "Er...."
(Of course, it translates loosely as Fairfield, but no-one I know calls it that, it would be like calling Porthcawl Soupgate. Heaven knows what he must have thought about 20 minutes later as we headed through LlanfairPG.)
