A trio of two car Class 165/0s in reverse numerical order at Islip on 28 July 2024. 165024, 165023 & 165022 work the specially strengthened 1Y21 08:11 Oxford to Marylebone Chiltern Railways service. On a normal Sunday this would just be a pair of units, but as the line was closed at Banbury, the only Chiltern Trains operating were the Oxford services, with passengers for Leamington Spa being bused from Bicester Village. Hence extra capacity was needed.
