Looks like the College is off today, as Bus Times is tracking the E400s on normal work

19205 is on 39s
19206 is on 35s
19207 is on 34s having worked a 12 first thing
19204 is now spare having worked half a 52 into Stockton this morning

As a result, 26278 is tracking on the normally-decker operated 58 turn and 26290 is on the decker 12 turns
