There were major signalling problems in the Marylebone area on 5 March 2026, which resulted in very late running and some cancellations in the morning. A short notice Oxford to Bicester train ran during the morning peak. 168328 & 168325 are pictured passing Oddington with the 2Z02 09:41 Bicester Village to Oxford Chiltern Railways service. The units had earlier ran 'wrong line' with the 2Z01 09:15 Oxford to Bicester Village special working.
