The line from Kabataş to Topkapı was previously served by tram Routes 12, 15, 16, 17, 22, 23, 24, 32, 33, 34 (see Trams in Istanbul). The Galata Bridge was also served by trams previously, although this bridge and other parts of the former tram route was totally unreserved track, while the present route is mostly on reserved track right of way. On the reserved portions of the line, rails are often raised like metro/suburban train to run fast, and stops on these parts have platforms, illuminated covering, etc.
