They will probably go somewhere else

The 180 trains are going to Grand Central for use between London King's Cross, and Bradford Interchange/Sunderland. Grand Central will then have all 14 Class 180's, and be able to strengthen some of its services up to 10 coaches. Plus, Grand Central also plan to open a new route from London King's Cross to Cleethorpes using two Class 180 trains coupled together, which will split into two 5 coach trains at Doncaster with 5 coaches to Cleethorpes, and 5 to Bradford, recombining into a single 10 coach train on the return.

I don't know the answer to this one as it's technically on loan to Hull Trains and they're meant to be getting new trains come Autumn/Winter anyway

a bit late now but they was traning them for hull trains because at the time hull trains needed them cause 180s was failing so they hired 1 HST set from GWR and hired them until IETS for hull trains. if this helps
