What are the benefits of introducing new trains for customers on other routes? (e.g. Oxford, Stratford-Upon-Avon, Aylesbury)?

These newer trains will deliver more reliable journeys on our route between London and the West Midlands. This will free up our existing trains (Class 168 and Class 165) for our other routes. This will result in customers seeing longer trains, which are also being refurbished with improved customer facilities over the next 18 months.
