Although Class 165 & 168 DMUs share the same multiple working equipment, they very rarely seem to work together. However, on 14 May 2025, 168219 & 165033 were paired up to work the 1T48 16:45 Marylebone to Oxford Chiltern Railways service, seen here passing Oddington. After returning to London, they split up, 168219 heading for Birmingham Moor Street, and 165033 doing another trip to Oxford.
