=== Electric fleet ===
The LIRR's electric fleet consists of 836 [[M7 (railcar)|M7]] and 170 [[M3 (railcar)|M3]] [[electric multiple unit]] cars in married pairs, meaning each car needs the other one to operate, with each car containing its own engineer's cab. The trainsets typically range from 6 to 12 cars long.

In September 2013, MTA announced that the LIRR would procure new [[M9 (railcar)|M9]] railcars from [[Kawasaki Heavy Industries Rolling Stock Company|Kawasaki]].<ref>{{cite web|url=http://www.mta.info/news/2013/09/19/new-railcars-lirr-metro-north-fleets|title=MTA – news – New Railcars for LIRR & Metro-North Fleets|work=mta.info|url-status=dead|archive-url=https://web.archive.org/web/20140226023600/http://www.mta.info/news/2013/09/19/new-railcars-lirr-metro-north-fleets|archive-date=February 26, 2014}}</ref> A 2014 MTA forecast indicated that the LIRR would need 416 M9 railcars; 180 to replace the outdated [[M3 (railcar)|M3]] railcars and an additional 236 railcars for the additional passengers expected once the East Side Access project is complete.<ref name="CPOC Jul 2014">{{Cite web |url=http://web.mta.info/mta/news/books/archive/140728_1200_CPOC.pdf |title=Capital Program Oversight Committee Meeting: July 2014 |date=July 28, 2014 |website=MTA |access-date=December 2, 2018 |archive-url=https://web.archive.org/web/20190524015314/http://web.mta.info/mta/news/books/archive/140728_1200_CPOC.pdf |archive-date=May 24, 2019 |url-status=live }}</ref> The first M9s entered revenue service on September 11, 2019.<ref>{{Cite web|url=http://www.mta.info/press-release/lirr/lirr-introduce-new-fleet-rail-cars-tomorrow|title=MTA {{!}} Press Release {{!}} LIRR {{!}} LIRR to Introduce New Fleet of Rail Cars Tomorrow|website=www.mta.info|access-date=September 12, 2019|archive-url=https://web.archive.org/web/20190914005505/http://www.mta.info/press-release/lirr/lirr-introduce-new-fleet-rail-cars-tomorrow|archive-date=September 14, 2019|url-status=live}}</ref>[[File:LIRR bi-level coaches.jpg|thumb|[[C3 (railcar)|C3]] bi-level coaches at a [[grade crossing]] in [[Bethpage, New York|Bethpage]]]]
