Very much so, but on some routes the Class 158 may have to be retained once the Class 156 have been disposed of (such as WHL, GSW, etc)
It is also possible that a next generation of the Class 170 may be utilised on the remaining Express routes, allowing capacity strengthening
However, even then there will be more rolling stock than services, so some will go
My understanding was that 158s couldn't do the West Highland line or the South Western? (hence 156s still being used)
