Regarding the service pattern along the Lancashire & Yorkshire route in an earlier post a few pages back, it seems that it is the intention to have a frequency of every 12 minutes between Manchester Victoria and Todmorden along that common section of route.
Of one of the 5 trains per hour that runs to Leeds via Brighouse, I would suggest that runs Southport - Leeds City calling at Meols Cop, Burscough Bridge, Apperley Bridge/Gathurst (alternating), Wigan Wallgate, Atherton, both Salford stations, Manchester Victoria, Rochdale, Littleborough, Todmorden, Hebden Bridge, Sowerby Bridge, Brighouse, Mirfield, Wakefield Kirkgate, and Leeds City. This to run every 60 minutes, with a portion detaching/attaching at Wakefield Kirkgate every 2 hours as an experimental service continuing to York calling at Normanton, Castleford, Sherburn-in-Elmet, either Church Fenton or Ulleskelf, and York. This portion could interwork with a 2 hourly service as an experiment from York - Sheffield via Pontefract Baghill.
The suggestion above would connect Manchester with Wakefield, as Wakefield is the historic administrative centre of the West Riding of Yorkshire, and it would reinstate a direct service along the complete route of the Manchester & Leeds Railway section of the L&YR. Also, there would be improved local and regional connectivity between the southern and eastern part of the West Riding with destinations in the North Riding via Castleford and Pontefract Baghill too, which could be tried as an experiment.
