Editing IND Concourse Line (section)

===Provisions for expansion===
The Concourse Line is mostly straight north of 161st Street–Yankee Stadium, but makes a slight right turn north of Bedford Park Boulevard to end at [[Norwood–205th Street (IND Concourse Line)|Norwood–205th Street]], with a provision to extend farther east.<ref name=NYTimes-OurGreatSubway-IND2ndSystem-1929>{{cite web|last1=Duffus|first1=R.L.|title=Our Great Subway Network Spreads Wider – New Plans of Board of Transportation Involve the Building of More Than One Hundred Miles of Additional Rapid Transit Routes for New York|url=https://www.nytimes.com/1929/09/22/archives/our-great-subway-network-spreads-wider-new-plans-of-board-of.html|work=The New York Times|access-date=August 19, 2015|date=September 22, 1929}}</ref><ref name=Raskin-RoutesNotTaken-2013/> The original [[IND Second System]] Plan in 1929 proposed extending the line to Baychester Avenue via Burke Avenue and Boston Road.

Preliminary engineering work for the extension along Burke Avenue took place in 1937 and 1938.<ref name=Raskin-RoutesNotTaken-2013 /> The city, however, found it easier and less expensive to purchase the railroad (now the [[IRT Dyre Avenue Line]]) and connect it with the [[IRT White Plains Road Line]], which hampered the Burke Avenue−Boston Road extension of the Concourse Line to Baychester Avenue.<ref name=Raskin-RoutesNotTaken-2013 /> In the 1960s and 1970 under the city's [[Program for Action]], it was proposed to extend the line a short distance to White Plains Road and [[Burke Avenue (IRT White Plains Road Line)|Burke Avenue]], at the [[IRT White Plains Road Line]].<ref name="int-arch">{{cite web | title=Full text of "Metropolitan transportation, a program for action.
