It would appear that the Alton line has been given back one of their beloved 444 diagrams (albeit different to the pre-2019 ones and this time TEN carriages not five)
0854/1524 to Alton (and interworking Basingstoke stoppers) have been 10-444 every day since the railway restarted after Christmas; I only mention this in the thread I made for Metro services because I expect this to be as a result of the requirement for more 450s on the Reading lines. Said Alton diagram formerly was 12-450.
I rather selfishly love this change, as a user of the Alton line when not at Uni, and someone who did appreciate the admittedly undeserved booked 444s.
