Personally I think that Wakefield loses a lot out of HS2, with (I’m guessing) a reduction of services to London via the ECML because of HS2 serving Leeds. If you could have a Wakefield station near the junction of the Leeds and York HS2 lines, that would be pretty good I think. It is also worth mentioning that it would be close to the M62, on a part where both the M1 and A1(M) are not far away. It is also a place where you can build platforms for the Normanton to Wakefield bit of line. I’ll pop a picture below to help explain it all better. It will be a screenshot of the HS2 interactive route map with a red dot to show the station location.
Alternatively (or also), I think that Sheffield isn’t the biggest winner out of HS2. Where the M1 meets the M18, you could build a parkway that serves Sheffield, Rotherham and the surrounding area. This could also mean the construction of an extra branch of the Sheffield Supertram towards this HS2 station, perhaps using the lesser used line through Tinsley and Catcliffe, before joining up with the Supertram At Meadowhall, where it would join up with the existing Supertram network. Once again, a picture is below in the same for most as the Wakefield one.
