That misses the point though. These trains currently provide a combined much higher frequency to the Calder Valley. It's only beyond there they deviateCurrently there is only 1 service at 2tph on the Calder Valley (Leeds to Manchester via Bradford) and 4 hourly services (Blackpool-York, Blackburn-Manchester, Leeds to Manchester via Brighouse, Leeds to Huddersfield via Brighouse).
