In 1998, SBS ordered 20 Trident chassis but due to overwhelming orders from bus companies in Hong Kong, these 20 chassis arrived late. Coupled with the late arrival of Duple Metsec body parts, the assembly of the 20 Trident buses was delayed. In August 2001, these buses were finally on the roads.
All 20 Tridents are based at Hougang Depot. Just before the second phase of the Northeast Line rationalisation exercise, Tridents were deployed on 51, 64, 85, 111, 501 and 502. After the exercise, the deployment of Tridents was shuffled. Currently Tridents are deployed on 51, 64, 80, 147, 153 and 165.
