- This will be the first train in SCR to have only two doors per coach (one on each side), as shown on the SCR twitter page.
- This train was added to celebrate 5 million visitors.
- Only the 3 coach version of the train has the special 5M visits livery following a similar system implemented on the Class 331
- Unlike Connect trains, this train and other Airlink trains have Leighton Stepford Road abbreviated as Leighton Step Rd. on their destination signs opposed to "Stepford Road" on Connect services
