Well

17027/9 both spent the morning on the late-starting 52 runs (17029 worked the 364 then onto 52s at 0850, 17027 worked the 0902 52) - 17029 was replaced at lunchtime by 24114 off the 36 (no need to realise what replaced that on the 36) while 17027 remained out until end of the day
In addition to 24114's reallocation, 3 MAN E300s were allocated off booked route from the start of the day - 24105/8 were both on 13s (in reverse order) while 24115 was on 14/34s (and 1 and a half 12s in that as well). As such, 22017/64/66/493 spent the day on 36s.
