From 29 September 2003 to 25 September 2004 Arriva ran a Loco hauled service between Knaresborough-Leeds-Carlisle-Leeds- Knaresborough using EWS class 37's and 4 Mark 2 coaches. The 37's were 37405/37408/37411. When any 2 of these locos were unavailable, some others were used 37042 (2) 37372 (3) 37521 (3) 37698 (2). On 2 occasions the train went to Carlisle with 1 x 37 (running round at Carlisle) and on 2 occasions 1 x 37 failed at Carlisle resulting in a doubleheader coming back to Leeds, and on 1 occasion the train went north with 3 x 37 on the train.
