LEYLAND ERT1/1 ROYAL TIGER WORLDMASTER - 3131

To enable the replacement of Sydney's tramway system by buses, three batches of 'Underfloor' type buses were ordered by the NSW Department of Government Transport. The first 100, Leyland OPSU1/1 Royal Tigers and AEC Regal IVs, were delivered in 1953 & 1954. This was followed by a further order for 250 buses.

 

125 of these were Leyland ERT1/1 Royal Tiger Worldmasters. The Leyland chassis' were built in 1956 in the UK and shipped to Sydney, where Cycle Components Manufacturing Company (CCMC, later Custom Coaches) of Guildford, Sydney, built the bodies in the years 1957 & 1958. They were registered in the 2902 to 3131 series. The 125 other buses in the order were AEC Regal IVs, bodied by Commonwealth Engineering of Granville, and these were registered in the 2882 to 3126 series. 

 

Finally a third Underfloor order of 388 buses, 206 from Leyland and 182 from AEC, was delivered from 1959 to 1961. These were bodied to a slightly different design (deletion of the 'standee' windows in favour of sliding top windows and a redesigned 'header' incorporating double destination rolls) by Commonwealth Engineering and Clyde Engineering. These buses were registered in the 3132 to 3519 range, and the Museum's AEC Regal IV Underfloor 3197 is representative of this final series.

 

3131 entered service in early 1959, initially from Enfield depot where it ran Cabarita / Mortlake - Burwood - Ashfield services. It later served at Brookvale, Willoughby, North Sydney, Burwood, Kingsgrove and Tempe depots during its DGT career.

 

The bus was withdrawn from Government service in 1983, by which stage it had been painted in the PTC blue & white livery, and purchased for preservation by a group of enthusiasts who had the bus returned to its original green & cream livery.
