WAGR Xb class

The WAGR Xb class were a total of 10 diesel-electric locomotives operated by the Western Australian Government Railways (WAGR) from 1963 to 1986.

The Xb was the result of converting standard X class locomotives by fitting them with multiple unit control (MUC) like the Xa class. Said locos were not fitted with communication doors or renumbered. None of the XB survived into preservation with the last being withdrawn from active service and scrapped in 1986.
