Why 172? How do they differ from 170s - are they the 75mph version?


Apparently yes, lighter weight, suburban layout, with similar bogies to the
220 Voyagers.

What happens if someone wants to order regional Turbostars from now on?
Do they get 100mph Class 172s, or some new Class 173 hybrid?

They will also have I suspect different engines - the MTU 183 (on
class 170/171) is no longer made.


In continental Europe the new-ish MTU 1800 is the 183 replacement -
but of course any new DMU could have any engine - MAN seem to be
gaining mainland popularity.
