Good those buses are at least in the electronic data. As you say hopefully in May they will make it to the pdf/paper timetable.
Given the limited timetable, a diversion of the 450 to Habrough Station will be off little use for rail connections, unless used in combination with CallConnect (if that serves Habrough?)/the NE Lincs alternative (the name escapes me right now). However for Habrough residents wanting to travel into Immingham for shopping it maybe useful.
I agree that a division of the 450 will be of limited use for rail connections, however it is better than nothing I suppose. The NE Lincs demand response service is indeed a viable alternative, thanks for the suggestion.
Concerning rerouting the 450 omnibus service, in order to serve Habrough the route would have to omit Killingholme. That would not be advantageous as Killingham - Immingham is the busiest part of the route.
I make a point of travelling on the 450 service from time to time and, unfortunately, there is next to no patronage from the villages of Thornton Curtis, Wootton and Ulceby, neither is there from the Wold villages (South Ferriby - Wrawby) except for the school runs. It doesn't help that a Tesco courtessy bus provides free competing transport at certain times. I would have thought that, rather than pay for their own 'bus, Tesco could reimburse customers who can show a valid ticket on the 450 route.
The 450 should be able to serve Habrough easily enough without having to omit South Killingholme, divert at Habrough Church down to the station then double back on itself to Habrough Church.
If the time penalty caused issues, then the practice of serving Barton Market Place twice on each journey could be dropped.
