On a recent foray up the Cambrian line - units 158835 and 158839 for clarity -
Leaving Birmingham New Street at 0825, all doors were in use and as usual with these services full and standing after Wolverhampton.
Upon arrival at Machynlleth, several hours later, the guard vacated those within the two rows of seats at each end of 839 heading to Pwllheli, and made an announcement that they were not to be used and people were to leave the train via the middle doors only. This of course caused a lot of aggro between passengers trying to board/alight on a now packed to the seams 158!
It was in aid of “social distancing” apparently.
Totally unacceptable, I know the rules differ slightly when crossing the border, but this was a step too far.
