The evening and Sunday service was indeed withdrawn in 2002 and the daytime frequency was reduced to its current half hourly status in 2003.

There was a three month (unsuccessful) trial extension from Seaburn to Whitburn in 1999/2000. Following the withdrawal of Service 21 in 2003 the 18/19 were ultimately extended to their current form to South Bents.

The last major revisions to the route took effect from 2005, with the closure of the Queen Alexandra Bridge. It was at this time that the revisions between City Centre & Grangetown and Grangetown & Prospect Hotel occurred, replacing links lost by the curtailment of Service 6. When the bridge reopened, the revised route was retained as the 6 was never reinstated on that section and was subsequently withdrawn entirely.
