The Ringer trailers had formerly been ACP 15, 19–22, 24–48 and BCP 1, 4–7 and 121–133 (ex. ACP 1–13). They took the number range 263T to 286T (ex ACP 25–48), 349T to 361T (ex ACP 1–13, later BCP 121–143), 362T to 367T (ex ACP 15, 19–22, 24) and 368T–372T (ex BCP 1 and 4–7).

From 1926–27 the first batch of Ringer Trailer to Driving Trailer conversions were made, with trailers 365 and 368–372 converted to 224D, 219D, 220D, 221D, 222D and 223D.

Then from 1965 to 1972 all bar two of the remaining Ringer trailers (349T and 350T) were converted to full Driving Trailers and coded randomly into in the range 226D–265D.
