An extremely unusual working took place over the Cotswold Line on 30 March 2021, when 37510 Orion took two former Arriva Trains Wales DVTs from Worcester (where they had been taken the previous day from Long Marston), to MoD Bicester by way of a reversal at Oxford. This was definitely not to be missed, but most locations on the southern end of the Cotswold Line would be less than ideal for lighting angle. However, the view from Grintleyhill Bridge, Combe, had the prefect lighting angle. 37510 Orion is pictured here approaching Combe with 82307 & 82308, running as the 5Q74 10:49 Worcester Hereford Sidings to Bicester MoD.
