800031 Charlotte Marsland passes Challow on 8 March 2022 with what would normally be the 1L66 07:24 Worcester Shrub Hill to Paddington GWR service. However, because the 6V15 20:18 Boston Sleaford Sidings to Swindon Stores steel train had failed at Sapperton, blocking the line, this unit had taken a slightly different route. It got as far as Gloucester as the 1L66, but then became the 5L66 08:13 Gloucester to Swindon empty stock working, travelling via Westerleigh Junction. It was then booked to work the very quickly arranged 1Z66 09:02 Swindon to Paddington, but clearly that wasn't going to leave on time, due to the longer route taken. It is pictured here running 20 minutes late.
