43187 Cardiff Castle passes West Hewish on 14 June 2023 with the 2C85 17:00 Bristol Temple Meads to Taunton GWR service. Although GWR call these short 'Castle' sets Class 255, that designation has no official validity. When they were introduced the Western Region sets were Class 253, and the Eastern Region ones Class 254. However, that was abandoned quite early on.
