'''Marmaray''' ({{IPA|tr|ˈmaɾmaɾaj|pron|MarmarayPronunciation.ogg}}) is a {{Convert|76.6|km|mi|adj=mid|-long}} [[commuter rail]] line located in [[Istanbul]], [[Turkey]]. The line runs from [[Halkalı railway station|Halkalı]], on the [[East Thrace|European side]], to [[Gebze]], on the [[Anatolia|Asian side]], along the north shore of the [[Sea of Marmara]]. Mostly using the right-of-way of two existing commuter rail lines, the Marmaray line linked the two lines via a [[Marmaray Tunnel|tunnel]] under the [[Bosporus]] strait, becoming the first standard gauge rail connection between [[Europe]] and [[Asia]] (all prior connections ran through [[Russia]] and used the incompatible [[5 ft and 1520 mm gauge railways|Russian broad gauge]]).<ref>Keith Fender, [http://trn.trains.com/Railroad-News/News-Wire/2013/10/Standard-gauge-rail-connection-from-Asia-to-Europe-opens-in-Turkey.aspx "Standard gauge rail connection from Asia to Europe opens in Turkey"], ''Trains'' (October 29, 2013).</ref> The two existing sections of the line were rebuilt and expanded from two tracks to [[Triple-track railway|three tracks]], to allow for higher capacity with intercity and freight rail. The name ''Marmaray'' is a [[portmanteau]] of the words ''Marmara'' and ''Ray'', which is [[Turkic peoples|Turkish]] for ''rail''.
