Context paragraphs:
Elevated railway: An elevated railway (also known as an El rail or simply an El for short, and, in Europe, as an overhead railway) is a rapid transit railway with the tracks above street level on a viaduct or other elevated structure (usually constructed of steel, concrete, or brick).  The railway may be standard gauge, narrow gauge, light rail, monorail, or a suspension railway.  Elevated railways are usually used in urban areas where there would otherwise be a large number of level crossings.  Most of the time, the tracks of elevated railways that run on steel viaducts can be seen from street level.

Satyajit Ray metro station: Satyajit Ray Metro Station is a station of the Kolkata Metro in Garia, a southern neighbourhood of Kolkata, India.  The station is named in honour of the great Bengali filmmaker Satyajit Ray.  The elevated structure is located above the Eastern Metropolitan Bypass.  The station is just in front of the Satyajit Ray Film & Television Institute, on the eastern side and the Garia Apex Hospital on the western side.

Brighton Park crossing: Brighton Park crossing is a major railroad crossing in Chicago, Illinois, hosting three of the major Chicago freight railroads.  The crossing is northwest of the intersection of Western Avenue and Archer Avenue, in the Brighton Park neighborhood of Chicago, Illinois.  The railroads involved in the crossing are CSX, Canadian National and Norfolk Southern.  The crossing consisted of the CN's two-track line in a roughly east/west orientation, crossing the five north/south tracks operated by NS and CSX.  Collectively, these railroads operate approximately 80 trains per day through the crossing.  The CN line was formerly the main line of the Gulf Mobile & Ohio and its predecessor Alton Railroad and currently carries Metra Heritage Corridor commuter trains and Amtrak passenger trains to St. Louis.  The GM&O's Brighton Park passenger stop was at this location.  The junction may be easily viewed from the CTA Orange Line trains that pass on an elevated structure immediately southeast of the crossing.

Anderson–Jerome Avenues (IRT Ninth Avenue Line): Anderson–Jerome Avenues was an elevated station on the Bronx extension of the IRT Ninth Avenue Line.  The station was opened on July 1, 1918 and in use by the Polo Grounds Shuttle from 1940 until it closed on August 31, 1958.  The reinforced concrete station structure extended from the end of the tunnel from the Sedgwick Avenue station over Jerome Avenue.  The tunnel emerges from the basement of an apartment building on Anderson Avenue.  A portion of the island platform is in the tunnel.  The station had entrances at each end of the structure on each side of Jerome Avenue and Anderson Avenue.  The entire structure was on a private right-of-way.  The structure east of the station was a two track steel structure north of 162nd Street that curved north to ramp up to the IRT Jerome Avenue Line elevated structure on River Avenue.  The ramp was built integrated with the Jerome Avenue Line structure and a stub of the curve remains.  An IRT electric substation is north of the curve stub.

Water tower: A water tower is an elevated structure supporting a water tank constructed at a height sufficient to pressurize a water supply system for the distribution of potable water, and to provide emergency storage for fire protection.  In some places, the term standpipe is used interchangeably to refer to a water tower.  Water towers often operate in conjunction with underground or surface service reservoirs, which store treated water close to where it will be used.  Other types of water towers may only store raw (non-potable) water for fire protection or industrial purposes, and may not necessarily be connected to a public water supply.

Calumet station (Illinois): Calumet is a station on Metra's Metra Electric Line located in East Hazel Crest, Illinois.  The station is officially located at Park Avenue and 174th Street, near the Calumet Country Club, however the actual location is on Wood Street south of 174th Street.  Park Avenue terminates at 171st Street.  Calumet is 22.82 mi from Millennium Station, the northern terminus of the Metra Electric Line.  In Metra's zone-based fare system, Calumet is located in zone E.  The station is on a solid-fill elevated structure and consists of one island platform which serves the Metra Electric Line's two tracks.

The Loop (CTA): The Loop (historically Union Loop, or commonly Loop) is the 1.79 mi long circuit of elevated railroad that forms the hub of the Chicago "L" system in Chicago, Illinois.  As of 2012, the branch has served 74,651 passengers every weekday.  The Loop is so named because the railroad loops around a rectangle formed by Lake Street (north side), Wabash Avenue (east), Van Buren Street (south), and Wells Street (west).  The railroad loop has given its name to Chicago's downtown, which is known as the Loop.  Numerous accounts assert that the use of this term predates the elevated railroad, deriving from the multiple cable car turntables, or loops, that terminated in the district, and especially those of two lines that shared a loop, constructed in 1882, bounded by Madison, Wabash, State, and Lake.  However, transportation historian Bruce Moffat has concluded that "The Loop" was not used as a proper noun until after Charles Yerkes' 1895–97 construction of the elevated structure.

Tubular Gallery: A Tubular Gallery is a large diameter, round, tubular steel structure used to enclose a troughed conveyor belt.  It is typically an elevated structure used to span over roadways, rivers or creeks or for use in shiploader systems.

Navy Street (BMT Myrtle Avenue Line): Navy Street was a station on the demolished BMT Myrtle Avenue Line.  It had 2 tracks and 1 island platform.  The station was originally built on February 13, 1888 for the Myrtle Avenue Elevated trains, but also served Lexington Avenue Elevated trains by 1891.  A segment of the Lexington Avenue Line once turned north from here onto Hudson Avenue and York Street on its way to the Fulton Ferry until 1904, when Lexington and Fifth Avenue trains were redirected along Myrtle Avenue west of this station.  It closed on October 4, 1969, after a fire on the elevated structure.  The next stop to the north was Vanderbilt Avenue.  The next stop to the south was Bridge–Jay Streets.
