Context paragraphs:
Auburn and Northern Railroad: Chartered in 1904 by the Beebe Syndicate, the Auburn and Northern Railroad connected the city of Auburn, New York, with the Rochester, Syracuse and Eastern Railroad at Port Byron, New York.  The railroad began operation in 1908.  In 1913, it was consolidated with the RS&E and the Syracuse, Lake Shore and Northern Railroad to form Empire United Railways.

Martisco Station: The Martisco Station, also known as Martisco Station Railway Museum, is a railroad station in Martisco, Onondaga County, New York.  It was built in 1870 by the Auburn and Syracuse Railroad, and is a two-story, Italianate style brick building.  Decorative brackets support an unusually long overhang of the roof.  The line and station were eventually acquired by the New York Central Railroad.  The station is owned by the Central New York Chapter of the National Railway Historical Society, and is open as a museum during limited hours in the summer.  Adjacent to the station is a contributing Pennsylvania Railroad dining car.

Auburn and Syracuse Electric Railroad: The Auburn and Syracuse Electric Railroad was an interurban rail that ran from Auburn, New York to Syracuse, New York, a distance of 24 mi .  The railroad owned a total of 58 mi of track which "was as fine as any in the state."

Panic of 1837: The Panic of 1837 was a financial crisis in the United States that touched off a major recession that lasted until the mid-1840s.  Profits, prices, and wages went down while unemployment went up.  Pessimism abounded during the time.  The panic had both domestic and foreign origins.  Speculative lending practices in western states, a sharp decline in cotton prices, a collapsing land bubble, international specie flows, and restrictive lending policies in Great Britain were all to blame.  On May 10, 1837, banks in New York City suspended specie payments, meaning that they would no longer redeem commercial paper in specie at full face value.  Despite a brief recovery in 1838, the recession persisted for approximately seven years.  Banks collapsed, businesses failed, prices declined, and thousands of workers lost their jobs.  Unemployment may have been as high as 25% in some locales.  The years 1837 to 1844 were, generally speaking, years of deflation in wages and prices.

Syracuse and Utica Railroad: The Syracuse and Utica Railroad was chartered May 1, 1836, and had to pay the state for any freight displaced from the Erie Canal.  The full line opened July 4, 1839, extending the line further to Syracuse, New York to Rome, New York (and further to Auburn, New York via the already-opened Auburn and Syracuse Railroad).  The road was consolidated into the New York Central Railroad in 1853.

Rochester and Syracuse Railroad (interurban): The Rochester and Syracuse Railroad was a double-track, high-speed line 87 mi long that ran between Rochester and Syracuse, New York.  The tracks paralleled the New York Central Railroad and the Erie Canal and had only one grade crossing with another railroad its entire length.

Rochester and Syracuse Railroad: The Rochester and Syracuse Railroad was incorporated on August 1, 1850, authorizing the consolidation of the Auburn and Rochester Railroad Company and the Auburn and Syracuse Railroad Company.  The consolidation also involved the acquisition of all the rights and property of the Direct Railway, established in 1848, between Syracuse, New York and Rochester, New York, and the construction of that road as a part of the consolidated road.

Oswego and Syracuse Railroad: The Oswego and Syracuse Railroad was formed April 29, 1839, and the route was surveyed during the summer of that year.  The Company was fully organized March 25, 1847.  The road was opened on May 14, 1848, and ran a total distance of 35.5 mi from Syracuse, New York to Oswego, New York.  In 1872 it passed under the management of the Delaware, Lackawanna and Western Railroad.

Market House (Oswego, New York): Market House, also known as The Market Hall and The D.L.& W. Hall, is a historic market building located at Oswego in Oswego County, New York.  It was built in 1835 and is a massive brick and stone structure overlooking the Oswego River.  The structure originally housed several government entities including city hall.  A new city hall was constructed in 1870 and completed in 1872.  A section of the basement is believed to have been used as a jail.  In 1864 the city sold it to the Oswego and Syracuse Railroad, that used it for the next 80 years as office and storage space.  The railroad upgraded the building with a bracketed cornice and elaborate cupola.

Auburn and Syracuse Railroad: The Auburn and Syracuse Railroad was incorporated on May 1, 1834, to provide easy access between Syracuse, New York and the Erie Canal.  Construction was begun in 1835, however, was delayed during the Panic of 1837.  Although the economic downturn lingered until 1843, the railroad was completed by January 1838.
