Three new brake vans appeared in 1929 numbered Z11379-11381 and a similar van was rebuilt from one of the type 1 vans (Z5067) in 1933-4. The old van retained its 4'-10" bogies when rebuilt and so differed from the other three. The fate of these vans is as given below:

No.	Later No.	Date renumbered	Fitted with electric light	Reclassified VZ	Written off
5067	85	March 1940	?	-	August 1963
11379	155	December 1939	June 1957	May 1974	January 1980
11380	156	February 1938	January 1956	-	February 1968
11381	157	April 1937	February 1956	May 1974	January 1983

The WAGR outline diagram is shown below. It is possible that other older vans were rebuilt to this type of body with Z23 being one candidate.
