I don't know if this is of use (or even possible) I was looking at prices for the train to Boro-- return from Manchester seemed to be just short of £100-- if possible booking return to Huddersfield and (at the same time ) return Huddersfield to Middlesbrough - cuts the cost by nearly 50%. No need to change trains . Obviously check if possible before doing it . If so ,watch out Martin Lewis. I am going from Huddersfield anyway so I haven't tried to do it.
