Interesting train, awful lighting! 50008 Thunderer & 67028 pass Heywood on 9 June 2021 with the 5Z50 09:17 Eastleigh Arlington to Westbury test run. I had intended to go to Broughton Gifford for this, but as it was picking up time, after a 75 minute late start, I decided not to risk the extra mileage, in case I missed it en-route. The horrible high midday lighting is made worse by the fact that the sun is only just on this side of the train.
