It’s a shame HS2 will no longer be serving the East Midlands as the removal of fast Sheffield trains from the southern MML could have freed up two paths each hour to run a semi-fast service. Perhaps something like a 2tph London - Leeds service but calling at St Albans, both Lutons, Bedford, Kettering, Market Harborough, Leicester, Loughborough, Nottingham (1tph), Derby (1tph), Chesterfield, Sheffield and then on to Leeds via the Hallam Line. Many towns along the M1 currently have no direct trains between each other, so such a service would encourage modal shift away from the roads.
