So Greater Anglia ordered two different train types for both their intercity and suburban services. What was the point in this given both have the same top speed? Surely you could have just ordered the same stock but with the intercity ones having just one door and suburban ones having 2 doors each carriage? I would have thought ordering the 720s for all would be better due to their better acceleration over the 745s. All GA needed to do was amend any intended for Norwich services to intercity style layout and have a single door per carriage?
