The company still had a large patronage on the former Govan Minibus Company routes and exploited this by running many services in competition with First Glasgow and Arriva. Gibson Direct, another Paisley company, accepted a number of SPT contracts in 2004, and was unable to continue its competition with Arriva on the busy 21 route linking Paisley, Renfrew, Braehead and Govan and thus the buses and route passed to FST. This was FST first route in Renfrew, especially unusual since their depot had been based in the town for some years. This also saw an influx of modern buses and a move to proper albeit small buses rather than minibuses. This service has returned to Gibsons in 2006. First's service cuts in 2005 saw FST become the only operator on the key "Paisley-Penilee-Govan corridor", a route that was well-patronised and run using double deckers with First, as well as the Nitshill-Govan service.
