37219 Jonty Jarvis 8-12-1998 to 18-3-2005 brings up the rear of the 1Z22 07:29 Derby RTC to Bristol Kingsland Road Network Rail test train at Grintleyhill Bridge, Combe, on 7 September 2022. 37421 is at the front of the train. Although an excellent vantage point, due to the extreme height of the bridge, unfortunately the vegetation on the right does now restrict the view in this direction.
