Mark 1 first class carriages retired early

[Rollmaterial]

The Mark 1 first class carriages are retired at the same time as the second class corridor carriages, creating a gap in first class carriage availability until the introduction of the Mark 2 carriages in 1964.

Thank you for your report: I have now put back the retirement date of the non-corridor first class mk. 1 carriage to match that of the non-corridor second class mk. 1 carriage.
