A pair of Irizar Centuries at Exeter St Davids on Sunday morning rail replacement duties. Although both are now operated by First Devon and Cornwall they bear evidence of previous work with First Beeline in the Thames valley. 23014 (nearest the camera; registration YN04AJX) is in a white version of First Group livery for RailAir services; 23008 (YV03UBA) carries Green Line livery for London express services.
