Shortly after sunrise on 30 May 2005, 166215 heads north from Tackley with the 2L22 05:55 Oxford to Banbury First Great Western. Unsurprisingly, this is the first local train of the day on the line. What is slightly more surprising is the use of a Class 166, rather than the more customary Class 165. This is one of the very few locations on the Cherwell Valley Line that is free of shadows at this ungodly hour in the morning.
