Hi, been lurking here for some time ...
I welcome the direct Leeds-Chester service and was annoyed Northern didn't fully publicise this at first, however I've got timetable leaflet 47 saved online

There's three major issues I have with the service at present :
1. Most services don't call at Helsby, Frodsham and Runcorn East. I understand the demand for a quicker service between Chester and Manchester stations, but extra services calling at these stops would relieve pressure on the corresponding TfW service.
2. There's a 2 hour gap on Mons-Fris (0617 then 0821) from Chester.
3. They don't run on Sundays.
