168112 & 168326 pass Oddington on 1 December 2021 with the 1T21 10:04 Marylebone to Oxford Chiltern Railways service. I had gone here for 37510 with the 5Q76 10:43 Bicester MoD to Lydney Up Goods Loop ECS, but as can be seen from the background, the clouds started to appear as soon as I arrived, and with no sign of movement from the 37, I abandoned it and went to Wolvercote for the test train instead. Of course, the ECS did run, but over half an hour late.
