Yes, I was told it was down to Business Class passengers not having access to a wheelchair accessible toilet in the same carriage. When there's only about ten Business Class seats, and no difference between the two classes other than the seat layout - and wheelchair customers would be in a space, not a seat - I struggle to believe that is a reason for unions to reject them. Besides, that's nothing to do with unions; unions work for themselves, not the customers (usually the primary targets of their actions), so why would they care?
Thanks for the update of the units. 045 was accepted at least a month ago now, but is yet to work in passenger service still, so I've noticed.
106 has been in service a while, I thought? RTT has shown it on Manchester North Wales services several days this week - yet to work to Cardiff, unfortunately for me.
