One of the hourly services is from Middlesbrough. notlob.divad was commenting on the second hourly service going to Manchester Airport which is required to serve York, Leeds and Huddersfield. I will not believe that there is demand enough from towns like Middlesbrough and Huddersfield or cities like York and Leeds that one service per hour is not adequate. This would mean a choice between Newcastle and Durham or Thornaby and Middlesbrough would need to be made.
I find it hard to believe that direct trains from Teeside to Manchester Airport are somehow crucial, given that places like Knutsford, Bangor, Stafford, Stoke-on-Trent, Barnsley, Nottingham, Derby, Wrexham and Leicester do not have direct Manchester Airport services and will have to do without them for the whole of the foreseeable future, and places like Rochdale, Bradford and Warrington are only now gaining them.
