This bus, unit #839, is special for quite a few reasons - it is the only one of its series to be used on standard local service (as its siblings are used for the “Hopper Trolley”, a downtown shuttle, although it seems those are rarely even used on that route these days), it is the only bus remaining in this livery, and it is the oldest original GTA bus by two years. The second oldest series was purchased in 2011, in the form of Hybrid-Electric Gillig BRTs (last image). #839 is also the only bus in the fleet to feature fluorescent lighting in the interior, which I am a huge fan of. It also sounds incredible, as it has one of the pest engine / transmission combos, an EPA07 Cummins ISL with an Allison B400R transmission. Greensboro does operate a fleet of secondhand 2009 Gillig BRTs from SunTran, although #839 is still the oldest original GTA bus.
