However, in 2000 these were in turn cascaded, and replaced by the last Alexander-bodied buses ordered by Metroline, TAL 118-134. This batch of TALs was thus unique. The TAs were moved to route 32, but have subsequently returned, partly to cover an increase in service on the 16. In early 2003, the 16 also included a large number of Dennis Dart single deckers, to free up double-deckers for the conversion of routes 139 and 189 to double-deck. However, full double-deck operation was returned by 17 February 2003, when the Mayor's congestion charge began.
