Hornell is nicknamed the "Maple City" after the large maple trees that once grew throughout the town and covered the surrounding hills of the Canisteo Valley. Hornell has the largest Saint Patrick's Day parade and celebration in the area, bringing many out to welcome spring and show their green. Hornell prides itself in its ever-growing and thriving business district.
What is now Hornell was first settled in 1790 under the name "Upper Canisteo", to distinguish it from the community of Canisteo, then known as "Lower Canisteo". The family of Benjamin Crosby were the first settlers in what is now Hornell. The area was incorporated as a town in 1820, as "Hornellsville." The name comes from early settler George Hornell Jr, who built the first gristmill here.
The City of Hornell was chartered in 1888 as the "City of Hornellsville," (having been first organized as the "Village of Hornellsville" in 1852). The name was changed to Hornell in 1906.
Major flooding in 1936 put parts of the city under water, prompting the creation of a system of levees to prevent future serious flooding issues.
The former city park, Union Park, was destroyed by the highway construction of the 1970s.
In 1950, Hornell had a population just above 15,000 people. It had two radio stations, WWHG and WLEA, and three movie theaters - the Steuben and the Majestic were located on Broadway, the Hornell on Main Street.
The current mayor[when?] of Hornell is Republican John Buckley.
In 2009, Kirk W. House produced Around Hornell, a historic photo book in Arcadia Publishing's "Images of America" series. Around Hornell also includes the surrounding rural communities of Canisteo, Dansville, Fremont, Hartsville, Hornellsville, and Howard.
Hornell had four rail lines, though the companies operating the railroads often changed names, routes, and ownership:
The most important railroad in Hornell was the New York and Erie Railroad, or Erie for short. It arrived in Hornell in 1850 and began public service on May 14, 1851. President Millard Fillmore, himself a native of western New York, and Secretary of State Daniel Webster rode through Hornell on the inaugural train.
Hornell was a central location on the Erie making it a favorable location for the railroad's repair yards. According to an 1882 traveler's guide to the Erie Railroad, in Hornell "There are an immense amount of side-tracks, ample engine-houses, repair-shops, and other railroad structures, as the village is the dividing-point of the Susquehanna and Western Divisions, and the point of junction of the Buffalo Division of the Erie Railway.... It has banks, newspapers, a nourishing library association, which maintains a course of popular lectures, and is one of the most efficient and attractive institutions of the kind in the interior of the State. There are churches of various denominations, and a population of about 9,000. The cars destined for Buffalo, Niagara Falls, etc., are here detached from those going west via Salamanca or Dunkirk. At the station is a spacious dining-saloon, where meals are served to travelers at regular hours."
In 1895 the Erie constructed "at the foot of Pine Street... an immense stock barn" for the large number of cattle being shipped east on its trains.
For the next hundred years Hornell enjoyed prosperity, with its steam engine shop doing the repairs for the entire Erie line. The most important point in town was the train station, which survives and is since 2005 housed the Hornell Erie Depot Museum. Next to it were the police station and fire department, at the beginning of Broadway, a wide street with stores, a luncheonette, and the Steuben and Majestic Theaters. Heading south, Broadway ended at Canisteo Street just before it passed under the tracks, a route served for some decades by a trolley. The underpass was closed, save for a pedestrian passage, when the Route 36 arterial was built.
At the five-way intersection just north of the underpass, where Broadway began, Canisteo Street ran northwestward. Near its southern end (now covered by the Route 36 arterial), was Hornell's largest hotel, the New Sherwood, the offices of the Hornell Evening Tribune and above it those of its radio station WWHG. On the east side was a storefront Greyhound station (service Elmira - Corning - Bath - Hornell - Batavia - Buffalo, no direct service to Rochester); on the west side was Hornell's main park, Union Park, destroyed by the Hornell Arterial, with the city's high school (middle school after new high school built), containing the city's largest auditorium, and other businesses. Main Street, with the Hornell Theater, WLEA's studios, Koskie's music store, and other businesses, connected the two now-separated streets (Broadway and Canisteo/Seneca ). Main St. extended east to Hornell's Carnegie Library (Hornell Public Library), Hornell's largest grocery store, Loblaw's, the YMCA, with the only public swimming pool in the city, various medical and dental offices, and finally (turning south and crossing the Canisteo River), the Erie Repair Shops. North of Main Street the downtown area extended another block with the city's pharmacy, Jacobson's, a shoe store, the United States Post Office (both now  vacant), and the Steuben Trust Company (bank). In the block north of Main Street, Church Street had Hornell's synagogue, Temple Beth-El (closed), and at the intersection with Genesee Street four churches, one on each corner; two survive today (2017). Further north on Seneca Street were Hornell's best restaurant, The Big Elms, Hornell's baseball field (from 1942 to 1957 Hornell had a minor-league team), and car dealers. The current high school is adjacent to the baseball field. The city ended at the Canisteo River, where a bridge led to the village of North Hornell.
Yet things were not idyllic in Hornell. In 1922, after a recruitment talk by "KKK organizer C. S. Fowler...at the local Grand Army of the Republic hall, the Klan announced its existence by igniting a huge cross on the side of a mountain, a demonstration evidently intended to intimidate the community's sizable immigrant population."
Hornell has struggled to regain its former prosperity. The population is half what it was in 1960, and still declining. Passenger service, in severe decline, ended completely by 1959. (The former station has been refurbished and since 2006 is the Hornell Erie Depot Museum.) The railroad came upon further hard times as trucking picked up more and more of the freight business. In October 1960 the Erie merged with the Lackawanna. Diesel engines, replacing older steam engines, required less maintenance;. Consequently many of the staff were laid off. The Erie Accounting Office, in Hornell, was closed and its work transferred to the Lackawanna headquarters in Scranton, Pennsylvania. In 1972, flooding from Hurricane Agnes destroyed about 200 miles (320 km) of roadbed along the Canisteo River, removing all hope of reoperating the railroad line southeast of Hornell. The company[which?] filed for bankruptcy soon after.
The former Erie repair shops are still a major employer. They were completely closed for years. Later they serviced EMD diesels as well as most of the bodywork and painting. They were operated by General Electric for a short time and then Morrison-Knudsen (both now part of Wabtec).
Today the Hornell shops are Alstom's main North American assembly and manufacturing site, producing AC traction motors, railway cars, and passenger locomotives. Car bodies are shipped disassembled from São Paulo, Brazil and assembled in Hornell. Alstom won a contract worth US$194 million to execute the complete overhaul of PATCO Speedline's light rail fleet, beginning in 2011. In 2013, the facility was contracted to build 34 light rail vehicles for delivery to Ottawa by 2018. In 2020 the plant began production of Acela Express Next Generation High-Speed cars for Amtrak.  In January 2021 the plant won a $1.8B contract, which is expected to create 250 additional jobs, to replace aging railcars in Chicago. The modern cars will feature amenities including video screens, bike racks, storage for bags, charging outlets, and cupholders. Access and safety are being improved by reducing the steps required to enter and exit. They will also be wheelchair accessible. 
Hornell's central layout changed significantly when the New York Route 36 arterial was built about 1972. Prior to that, Route 36, Hornell's main north-south highway, was routed along Seneca Street (to the north) and Canisteo Street (to the south). Neither of these streets were adequate for the increased automobile and truck traffic which accompanied the decline of the railroad, and they could not be easily expanded. Canisteo Street also had a significant bottleneck (originally the "Canisteo Subway" on the Hornell-Canisteo trolley, pictured on a postcard) where the route went under the Erie Railroad tracks, just south of downtown. Route 36 between Hornell and Canisteo, also inadequate, could not be expanded due to the adjacent Canisteo River.
The decision was made to replace the route with an arterial, west of Seneca Street on the north side, crossing the downtown and exiting Hornell east of Canisteo Street on the south side. "The highway required the demolition of 245 houses and many commercial buildings, split the city in half, and sacrificed Hornell's Union Park." The four-lane route was continued to Canisteo. Unconnected fragments of the former Route 36 from Hornell to Canisteo survive; in Hornell it starts from East Avenue, east of the river, and heading north from the Village of Canisteo it is today Dineen/McBurney Road.
The impact of the relocation of Route 36 on central Hornell was profound. Much of the south end of the downtown was destroyed, either physically or economically. Seneca Street and Broadway, formerly important commercial streets, became deserted side streets. (See United States Post Office (Hornell, New York).) It is not fondly remembered, and it was something wanted by the trucking industry and its customers, not the local working class.
When the decision was made in the 1960s to upgrade the western portion of New York Route 17 to expressway status, it was decided to route the expressway through the Hornell area, as it was considered to have more prospects for development than Greenwood and Jasper, along the old route (now New York Route 417). Interstate 86 runs from I-90 near Erie, Pennsylvania across New York's Southern Frontier to Windsor, NY. It crosses Route 36 between Hornell and Arkport. It is today Hornell's main highway.
