In 1945 a new set of six suburban cars including 4 AY’s (#452 – 455) and two AYB’s were built. In 1946 another 2 AY cars (#460 & 461) and 2 AYB cars were built supplementing the ageing fleet of sidedoor/dogbox style cars predominantly in use on the suburban network.
AY 452 is seen here below modelled in the "All over Green" livery
The AYL cars saw use on the “Westland” until 1969 and “Kalgoorlie” services till 1971 when “Standard Gauge” services commenced and they were no longer required. Some use of the AYL cars were made on Shopper, Bunbury Belle and Tour/charter trains until being written off in 1975. The above picture of AYL 29 shows the livery it carried in 1962
The AY suburban cars were used on loco hauled sets until 1991, being displaced by new Electric railcars.
