I took two Merseyrail trains today, Chester to Liverpool and Liverpool to Southport, and I'm almost sure I didn't hear "that" announcement once. I may have missed it, but to miss it on two trains would be surprising. Perhaps they read this forum.
Really lovely guard on the TfW Cardiff to Holyhead, he made several announcements but they were all useful stuff, like despite us running a few minutes late into Shrewsbury, so was the Aberystwyth & Pwllheli train, so don't worry as you will most likely still catch your connection (he included arrival and departure platforms and how to get between them), and at Chester explaining that the doors wouldn't open immediately as they had to detach two coaches at the back. No rubbish or "I like the sound of my own voice" nonsense, just what people needed to know.
