A bus powered by an internal-combustion engine fed with gasoline (petrol). The world's first scheduled motorbus line opened on 18 March 1895, when the newly founded Netphener Omnibusgesellschaft used two Benz omnibuses — built by Benz & Cie of Mannheim — to run between Siegen, Netphen, and Deuz in the Siegerland region of western Germany. The vehicles carried 6–8 passengers, ran on a 2.9-litre single-cylinder engine producing 5 PS (3.7 kW), and had glazed windows and heating. They were not, in retrospect, ready: the engine was too weak for the route's two main hills (passengers had to push), repairs required a mechanic from Mannheim, and operations stopped in December 1895 after carrying about 10,000 passengers in nine months. The category nonetheless took off elsewhere within a decade — Daimler-Motoren-Gesellschaft and other manufacturers produced more reliable petrol buses by the early 1900s, London replaced its last horse omnibus in 1911, and the gasoline bus dominated city operation until being itself displaced by the diesel bus from the 1930s onward (and, on heavily-trafficked routes in postwar Europe, by the trolleybus). Petrol remains the propulsion of choice for shuttle, school, and tourist buses where small fleet size makes a diesel maintenance program uneconomic.[1,2]
Role. Founder of Benz & Cie; manufacturer of the first motorbus chassis
Contribution. Benz & Cie built both vehicles used on the Netphen line. The bus used a horizontal single-cylinder rear-mounted engine with 2.9 L displacement, 5 PS, glazed windows and heating — adapted directly from Benz's 1885–1890s passenger car platform.
Role. First scheduled motorbus operator
Contribution. Founded specifically to run the Siegen–Netphen–Deuz route. Rural rather than urban: the Netphen choice mattered because the Royal Prussian Postal Service had refused to extend its post-coach service into the area, leaving an underserved corridor that an entrepreneur could fill.
Role. Inventor of the four-stroke internal-combustion engine (1876) — the propulsion technology the motorbus depends on
Contribution. Otto's compressed-charge four-stroke engine, patented in 1877, is the direct ancestor of every petrol bus engine. Carl Benz used the Otto cycle in his 1885 Patent-Motorwagen and in the 1895 Netphen buses.
The motorbus inherits the horse omnibus's route-and-timetable model wholesale; only the propulsion changes. In the 1890s and 1900s many cities ran horse and motor buses on the same routes side-by-side.
Walter Hancock and Goldsworthy Gurney ran steam buses on British roads in the 1830s; the 1865 Locomotive Acts (the 'Red Flag Acts') effectively killed them by capping speeds at 4 mph and requiring a man with a flag to walk in front. They were a competing ancestor that lost to legal restriction long before the motorbus was technically possible.
Werner von Siemens's electric trolleybus prototype demonstrated electrified bus operation 13 years before the petrol bus. The two propulsion technologies competed for the next century.
Role. Provides the on-board power that lets a bus operate without rails or overhead wires. The 1895 Netphen buses used a 2.9 L single-cylinder Benz engine; the technology line runs unbroken to today's diesel and CNG transit fleets.
Role. Solid rubber tires were standard on early motorbuses (the 1895 Netphen buses had them). Pneumatic tires, scaled from Dunlop's 1888 bicycle tire, made motorbus rides tolerable for passengers and dropped the unsprung mass, enabling higher speeds and lower road damage. By the 1910s pneumatic tires were standard equipment.
Role. A motorbus on a 30-km rural route needs reliable refuelling. In 1895 there was effectively no such network — fuel had to be stockpiled at the operator's depot, and parts came from Mannheim by train. The petrol bus could not scale until the 1900s when chemists' shops, then dedicated filling stations, made fuel routinely available.
Role. The Netphen line's downtime — days waiting for a Mannheim mechanic — was the binding constraint, not engine power. Motorbus operators developed a depot-based repair practice (own mechanics, own spare parts) that became the model for transit maintenance generally.
Why it failed. Killed by Britain's 1865 Locomotive Act ('Red Flag Act') which required a man with a red flag to walk in front and capped speeds at 4 mph in towns. The act was repealed only in 1896 — by which point the petrol bus had a head start that steam never recovered.
Why it failed. Briefly a major competitor to both motorbuses and streetcars — by March 1915 thousands of jitneys ran in southern and western US cities. Killed within four years by combinations of liability insurance requirements, route restrictions, and operating-time limits sponsored by streetcar companies and supportive municipalities. By 1918 over 90% of 1915-era jitneys had ceased operating. The pattern (entry-permissive technology, regulatory rollback to protect incumbents) repeats with later transit-network challengers.
A locally-organised private company financed the route and the two Benz buses. The post office's refusal to serve the route created the opening.

On 18 March 1895, the world's first public transport line operated by a motorised bus rather than a stagecoach was opened. The newly founded Netphener Omnibusgesellschaft opened the first ever bus route from Siegen via Netphen to Deuz.
The Benz Omnibus was the first internal combustion engine-powered omnibus in the world, built by Benz & Cie of automotive pioneer Carl Benz and had eight seats, including the driver's seat.
Both vehicles were powered by a horizontal single-cylinder engine in the rear with a standing flywheel and 2.9 liters displacement, delivering 3.7 kW (5 PS).
After 14 years of research and development, Otto succeeded in creating the compressed charge internal combustion engine on May 9, 1876, finding a way to layer the fuel mixture into the cylinder to cause the fuel to burn in a progressive, as opposed to explosive fashion.
The Locomotives Act 1865 (the 'Red Flag Act') imposed on road locomotives a speed limit of 2 mph in towns and 4 mph in the country. It increased the crew to three, of which one was to walk 60 yards ahead carrying a red flag.
The Electromote was the world's first vehicle run like a trolleybus, which was first presented to the public on April 29, 1882, by its inventor Dr. Ernst Werner von Siemens in Halensee, a suburb of Berlin, Germany.
The technology was still quite sensitive and in need of frequent repairs, so that the bus could often not be used for days until a mechanic travelled from Mannheim with necessary replacement parts.
The Locomotive Act 1865 (also known as the 'Red Flag Act') was introduced as a result of the increasing popularity of self-propelled traction engines (known then as 'road locomotives') on British public thoroughfares after 1850.
The Locomotives on Highways Act 1896 defined a new class of light locomotives weighing less than 3 tons, to which the 1861, 1865 and 1878 Locomotive Acts did not apply. This removed from such vehicles the requirement for a crew of three with one man walking ahead, the speed limits and the bridge restrictions.
By July 1915, twenty-seven municipalities had already imposed burdensome liability costs to all jitney drivers. Drivers were compelled to post up to $10,000 in liability insurance, biting into 25 to 50 percent of drivers' annual earnings. By 1918, more than 90% of the jitney services that opened in 1915 had ceased operations.
It has been claimed that the restrictions in the earlier act were advocated by those with interests in the UK railway industry and horse-drawn carriages.
For example, in Salt Lake City, a new city ordinance went into effect on April 1, 1915, and by April 4 nearly all of the SLC Jitney operators surrendered their licenses leaving only 2 Jitney busses in operation out of a previous fleet of nearly 40.
On 18 March 1895, the world's first public transport line operated by a motorised bus rather than a stagecoach was opened.
Carl Benz established the first practical automobile manufacturing company in 1885 and used the Otto engine design in his automobiles.
To increase reliability, the bus company purchased a second vehicle on 1 July 1895. However, this would not bring any lasting improvement and operations were discontinued again in December of the same year. The first motorized omnibus line in the world transported over 10,000 people during its operational period.
The jitney movement began in late 1914 in Los Angeles, when enterprising Model T owners discovered they could offer seats in their private cars for the same fare as a trolley: a nickel, or 'jitney.' The first documented jitney operation began on July 1, 1914, when driver L.P. Draper used his Ford Model T to transport a passenger for five cents. By March 1915, thousands of jitneys operated in the southern and western United States.
