Roughly 800 buses,200 streetcars and 40 cable cars see active duty. Munis cable cars constitute the oldest and largest such remaining in service in the world and is the only one still running with manually operated cars in street traffic. Its fleet of trolleybuses is the largest in the United States. Muni is in the process of replacing its motor coach fleet - the first of which was procured in 1915 - with diesel-electric hybrid buses, a summary of the current and historic vehicles follows. §5454,6238,6244,6259,6291,8173,6238,6244,6291, and 8173 written off due to a fire, and 5454,6259, and 8319 written off due to an accident. ^8448 Wi-Fi equipped from 2008 to 2009, the Connected bus, ♦8101-8235 and 8301-71s turn signal is different when rehabilitated in 2013. Muni also tested a 40-foot double-decker bus from Alexander Dennis Limited but the bus is now retired. As the Neoplan buses are assigned to the reserve fleet. Reserve fleet buses are only in service as needed, the following are a list of buses that are currently assigned to the training fleet. These buses are sometimes revenue service as reserve fleet, and are used to train prospective operators, the following shows the buses previously operated by the SFMTA. Some of these coaches have been preserved in the fleet, donated to trolley museums. There are 11 divisions for the Muni buses, ETI 14TrSF Skodas #5401-5489 and NFI XT60 Vossloh Kiepe #7201-7260 are from the Potrero Division, while #5490-5640 are from the Presidio Division, the latter holds only 40-ft ETI Skoda trolleybuses. The Kirkland Division uses only Neoplan AN440 diesel buses, the 30 and 40-ft Orion VII diesel-electric hybrid buses, and New Flyer XDE40s all rest in the Woods Division. Some Neoplan AN440s also lie in the Woods division as the fleet and are used only as needed. The division where the Neoplan AN440s that are rehabbed in 2013 lies in are the Kirkland Division, the test buses that retired that is moved. Munis active diesel fleet contains coaches ranging from thirty to sixty feet in length, for the last complete fleet replacement cycle Muni bought from three manufacturers, NABI, Neoplan and Orion, all of whom no longer sell buses in the U. S. Muni has since purchased 40 ft. and 60 ft. buses from New Flyer with options to replace the remainder of the fleet in those sizes. In 1984, Muni received its first 60-ft articulated buses, which were used on high-ridership routes because the buses carried more people than the standard length bus, in December 2007, Muni acquired a double-decker diesel bus for testing purposes
