fleet mainly consisted of Alexander-bodied Bristol REs, Leyland Leopards, Leyland Tigers and Volvo B10Ms. Many of these would be hijacked and maliciously destroyed throughout The Troubles, and as such, second-hand Bristol, Leyland and AEC buses were regularly purchased from British operators. The last Leyland Tiger of a fleet of over 600 was handed over to the company in September 1993, with Ulsterbus moving over to the Volvo B10M following the closure of Leyland Bus. Most high-floor Ulsterbus buses were withdrawn by the mid-2000s; the last Leyland Leopards were finally withdrawn in 2006, with 681 being built for Ulsterbus and 228 of these being maliciously destroyed. Following an order for 40 Leyland Atlanteans in 1971, no further double decker buses were ordered, as they were seen as expensive to run and not offering good value for money at the time. In 2001, however, double decker buses were reintroduced to Northern Ireland through the purchase of 20 low-floor Volvo B7TLs with Alexander ALX400 bodywork for both Ulsterbus and Citybus.
