Chiltern RailwaysThe Chiltern Railways is a railroad that operates out of London Marylebone to Birmingham Snow Hill (about 112 miles of track). Now you maybe thinking that 112 miles is a lot for a DTG Productions, but I am only expecting them to do London Marylebone - Banbury. That distance is about 70 miles which makes perfect sense. ------------------------------------------------------------------------------------------------------------------------------------------------- Rolling StockThere are different types of trains on the Chiltern Railways. For local commuter trains there is the Class 165 which does services from London Marylebone to Gerrards Cross/High Wycombe/Aylesbury/or Banbury. Then there is the Class 168 that does intercity service along with the Class 172, Class 68, and the Mark 3 Coach System. Class 165 - Class 168 - Class 172 - Class 68 - Mark 3 Coach System -
