- The Class 331 is the first of the Civity trains in service in SCR.
- This train was the last "paper train" to be added to the game.
- This train was added in celebration of 3 million place visits to SCR, and as such the 331/0 units have a special livery to commemorate it. This is similar to the Class 730 livery, which celebrates one million, and the Class 755/3 livery, which celebrates five million.
- Many players agree that this train was rushed, which would explain the somewhat poor texturing. The fact that this train was rushed meant that something big was coming to the game, as BanTech stated that "exciting updates were coming" to SCR.
