to board without any additional fares being assessed. However, despite the fare integration, passengers boarding with YRT passes will not be issued transfers for connecting to Brampton Transit routes in Brampton, and passengers boarding with Brampton Transit passes will not be issued transfers for connecting to YRT routes in York Region. Brampton Transit and YRT have cooperated on routes connecting Brampton and Toronto via York Region, and for a time, certain YRT routes were jointly operated by YRT and Brampton Transit buses, where both agencies' fare media were accepted. The introduction of Züm Queen has ended operation of YRT route 77 to Bramalea City Centre. The acceptance of YRT fares on Brampton Transit routes in York Region are the last vestiges of such cooperation. Vehicles and fleet rosters YRT has 123 Viva bus rapid transit vehicles, 406 YRT buses, and 97 Mobility Plus vehicles. The initial fleet consisted of buses from previous York Region operators, but has since been expanded with YRT-bought vehicles. Fleet colours YRT's first fleet (2001–2006) was painted with a white base with blue and gold stripes. During the early years many buses still had their pre-2000 colours from the previous operators with "YRT" painted on the front and sides. The livery was changed On 2007 to a white and several tones of blue. Only the Viva fleet is all-blue, but one Orion I YRT (#2028) was painted all-blue for a colour demo. During the transition to the second colour theme some buses were all white with the old "YRT" label remaining. Transit enforcement Fare Inspectors and Special Constables patrol the entire YRT transit system for the safety and security of passengers and to ensure compliance with the proof-of-payment system used on Viva buses. They do random spot checks on board Viva buses to ensure the proper use of tickets, transfers and Presto cards. There is a time limit to be riding while paying one fare, and passengers without valid fares (even those whose two-hour travel window expires while on board a vehicle) are subject to a warning, fine, or a criminal charge. CCTV cameras In 2006, YRT began installing 150 cameras on YRT (including Viva and Mobility Plus) buses. By the end of 2008, there were to be 210 more cameras added to the system's vehicles. CCTV cameras are also installed in some of the Vivastations in Richmond Hill. Routes YRT-owned facilities YRT owns a few
