From November SWT will start to receive trans-pennine 158s.
Each unit will go initially to Fratton for mods/refurbishment, the same
as 786/789.
After each modified unit has completed X amount of miles in service, a
170 will be returned to Porterbrook.
Unsurprisingly 170392 will be the first to be returned.
Good! no more new trains at Waterloo
