They are identified as 255s on traction cards and similar internal systems in the same way 253 was still used for full length HSTs. 257 was used for short slam door sets.That's an interesting decision. One that I can't seem doing anything other than pleasing a few enthusiasts. I do like the nameplates I'll be honest.
The designations were introduced on some internal systems as the characteristics of each set type are different enough to warrant separate identifiers.
