Looking at RTT, these appear to be diagrammed as follows? But there are some mysteries.
(A and B indicate portion workings)
1D80 0530 Birm to Holyhead arr 0822 - (is this a double unit? If not, how does 1A50 get to Holyhead?)
1A26 0853 Holyhead to Euston arr 1235
(this arrives on platform 15, from which the next deprature is 9G21, 1240 to Birmingham) In the present timetable, it seems the next diagrammed working for this arrival is 9J38 1816 Euston to Shrewsbury)
1A50 (A) 1248 Holyhead to Euston arr 1637
1D91 (A) 1702 Euston to Holyhead arr 2058
1A14 (A) 0648 (next morning) Holyhead to Euston arr 1035 then to depot
1D89 departs platform 2, but the previous arrival on that platform is 1A39 at 1441 from Manchester. In the present timetable, 1D89 is formed from the incoming stock of 1a38 (1232 Chester to Euston arr 1437, which Post 2105 says will still be a 221)
1D89 (B) 1502 Euston to Chester arr 1705
1A68 1732 Chester to Euston ar 1935
1D94 2002 Euston to Holyhead arr 2341
1A14 (B) 0648 (next morning) Holyhead to Euston arr 1035 then to depot
1D89 (A) 1502 Euston to Holyhead arr 1847
1G00 1948 Holyhead to Birmingham arr 2251
1A19 0920 Chester to Euston arr 1135
1D86 1202 Euston to Chester, arr 1407
1A50 (B) 1432 Chester to Euston arr 1637
1D91 (B) 1702 Euston to Chester arr 1913
No doubt all will become clear

Will any of the 805 services starting in June stop at Milton Keynes?
Also, does anyone have any info on when we can expect the first 807s out on fault-free runs?
9G26 14.16 Euston - Birmingham and
9G38 18.16 Euston - Wolverhampton both call at Milton Keynes from the June timetable change M-F.
