infrastructure had been modernised by 2018. The light rail service is expected to be expanded by upgrading existing tram lines to light rail status. Most trams operated by STB (all V3A, Bucur 1 and Bucur LF models) are manufactured internally by STB at their subsidiary URAC Bucharest (the same subsidiary also handles tramway repairs and is in charge of scrapping vehicles reaching the end of their useful life). Currently, URAC produces three models for STB – two three-section, partially low-floor, wheelchair-accessible models (V3A-CH-PPC/CA-PPC derived from the earlier V3A-93 model and the all-new Bucur-LF model) as well as a two-section, non-wheelchair-accessible model (Bucur 1), made from scrapped Tatra axles with new equipment. It is uncertain if their production will continue, because as of now their production has been halted for the past 7 years. Routes 1, 10, 21, 25, 32, 41 are wheelchair-accessible, using new V3A-93-M2000-PPC, V3A-CH-PPC and Bucur LF trams. Lines 3, 7, 8, 19, 23, 24, 27, 45 are also wheel chair accessible when V3A-93 PPC (3, 7, 19, 24, 45 - number is limited to 4 vehicles, 008, 164, 181 and 206 can be seen on these routes occasionally, the first two (008 and 164) mainly on routes 3, 24, 45 and the following two (181 and 206) on routes 7 and/or 19) or CA/CH-PPC are sent on these routes ( the latter mainly 8, 23 and 27 from Alexandria on 8 and Dudesti 23/27). Other routes (if most) will become wheelchair-accessible as soon as more V3A-CH-PPC or Bucur-LF vehicles are constructed (URAC's building and modernising capacity is limited). The maximum speed of trams in Bucharest is . Fleet In 2018, the STB had a fleet of 486 trams, most of which were the V3A-M type (323 trams). The fleet is spread across 7 tram depots and 1 mixed tram-trolleybus depot. The fleet utilisation rate during workdays stood at 55.6% in 2018. Tickets Surface transportation, operated by STB uses a different ticketing system from the metro network, operated by Metrorex, a separate entity. Their tickets and prices can be found on their website, available in English as well. http://www.stbsa.ro/ They include subscriptions, rechargeable cards as well as single use cards. A simple metropolitan ticket valid on all surface lines for 90 minutes costs 3 RON and can be activated by tapping either a STB transit card or a contactless bank card on the ticket machines present inside all
