Background Delhi Sarai Rohilla railway station was established in 1872 when the construction of the metre-gauge line from Delhi to Jaipur and Ajmer was underway. Located just outside the walled city of
Shahjahanabad, it served as a focal point for metre-gauge trains traveling to
Rewari,
Punjab,
Rajasthan, and
Gujarat. The line from
Delhi Junction to Sarai Rohilla was double-tracked, whereas the section from Sarai Rohilla to
Rewari remained single until it was later upgraded. From Rewari, single tracks diverged in five directions. at platform 1
Gauge conversion The conversion of the metre-gauge to
broad gauge began in 1991. As part of the Ajmer–Delhi line conversion, one of the double metre-gauge tracks on the Delhi–Rewari line was converted to broad gauge in December 1994. Within a few years, both tracks from Sarai Rohilla to Delhi Junction were converted to broad gauge, eliminating metre-gauge train operations at Delhi station. Consequently, all metre-gauge trains were redirected to Sarai Rohilla, which was thereafter designated a terminus. By September 2006, the second metre-gauge track from Sarai Rohilla to Rewari was converted to broad gauge, and metre-gauge train operations between Rewari and Sarai Rohilla ceased. However, the newly converted track was opened for public use only in October 2007. ==Infrastructure==
