Furthest north...Leeds - it used to be York, but now a change is required at Selby. The train service to York is very good (several trains per hour, journey time 20 mins) but very expensive unless there is a special offer. There are even more trains to Leeds, but the journey time is 45 mins.
Furthest south...Sheffield or Lincoln I think. There used to be a direct bus service to Nottingham and Leicester. The train service to Sheffield is excellent, very infrequent to Lincoln, and travel to Nottingham and Leicester is via Sheffield.
Furthest east...Scunthorpe. There used to be regular daytime services to both Hull and Cleethorpes, but since trains serve both destinations the buses were cancelled.
Furthest west...Barnsley or Leeds. There is no rail link to Barnsley.
