Chiltern Railways MK3 Commuter Set
Chiltern Railways has a set of 7 Mk3s referred to as either the "Commuter" or "Banbury" Set. These were not fitted with sliding plug doors like the "Silver Trains" used on the flagship route between London Marylebone and Birmingham/Kidderminster. The set runs 2 services per weekday (Mon-Fri) between Marylebone and Bicester/Banbury. The livery on these Mk3s is similar to the Chiltern "Mainline" livery used on the Class 168s.
