Double-decker bus
In October 1953, a single AEC Regent III double-decker from the fleet of the Kuala Lumpur, Malaya-based General Transport Company was sent to Singapore for demonstration. It was used on service by the Singapore Traction Company for two weeks. After that, it was inspected by two other bus companies, and then sent back to KL. However, no orders for double-deckers immediately followed.
