Our Huddersfield correspondent Michael Sayer has been in contact to provide some photos showing that Norwich is not the only part of the First group using the colour coded routes on its buses.
The first shows, not a Norwich Red Line 23/24 but First Hudersfield's 37525 (YN58 ETT) on the Holmfirth Connection 310 route .The bus is leaving Holmfirth bus station on its outward journey from Huddersfield to Hepworth on 4th April
Captured on camera the same day is First Halifax's 32526 (YJ54 XUT ) on ZEST branded orange route 503. The bus is pictured at Elland on the Huddersfield to Halifax route.
Mike's final contribution is First Huddersfield's 37295 (MX07 BTZ) leaving Holmfirth on the 310 route towards Huddersfield.
