By 1994 the garage was worked almost entirely by Leyland Olympians and MCW Metrobuses with a few Dennis Dart and MCW Metroriders. There was also a period where the then South London Transport regularly transferred vehicles about, and whilst Thornton Heath retained its Olympians throughout, they were joined not only by Metrobuses but also Leyland Titans. Thornton Heath also briefly flirted with SR-class StarRiders, as well as sharing vehicle evaluation duties with Bromley for the DA/SA classes of vehicle, operating SA1 From October 1989 to February 1990 before swapping it for DA1, which stayed here for a further 6 months before being moved to Westlink.
