I have made the list of Class 222 in 9 and 4 carriages that they used to be. The Standard Class is in the front row of the carriages and the First Class is in the rear of the carriages. Maybe they could be reformed by in their original carriage formations, after they are withdrawn from EMR in either 2024 or 2025 in the future.
Here's the example of the carriage formations that the Class 222s will be look like.
