166201 calls at Charlbury station on 9 May 2021 with the 1P49 12:13 Worcester Shrub Hill to Reading GWR service. I really didn't think I would ever see a First Great Western blue liveried Class 166 on the Cotswold Line ever again, as the few remaining units were transferred away from the area some time ago. However, the Class 800 crisis has resulted in 166201 briefly returning to its old haunts. A pity the weather was so dire!
