Royal Commission

Although this may have been the result of a contemporary anti-American bias, these locomotives were said to be too heavy and too wide at the cylinders, and were the subject of a Royal Commission.[5]

Withdrawal

2305 was the first withdrawn in May 1933. By 1941, only six were left, with the last, 2304, being withdrawn in September 1946.[1] None has survived onto preservation.
