Editing Bus (section)

===Configuration===
Buses were initially configured with an engine in the front and an entrance at the rear. With the transition to one-person operation, many manufacturers moved to mid- or rear-engined designs, with a single door at the front or multiple doors. The move to the low-floor design has all but eliminated the mid-engined design, although some coaches still have mid-mounted engines. Front-engined buses still persist for niche markets such as American school buses, some minibuses, and buses in less developed countries, which may be derived from truck chassis, rather than purpose-built bus designs. Most buses have two [[axles]], while articulated buses have three.{{citation needed|date=July 2021|reason=I haven't seen a modern bus with two axles in years.}}
