Delhi Sarai Rohilla railway station (station code: DEE) is situated about from old Delhi railway junction in India. It is managed by Delhi Division of Northern Railway zone. Many trains from Delhi to Haryana, Punjab, Rajasthan and Gujarat stop at this station. More than twenty trains including Duronto and AC trains originate at this station. Etymology Sarai means an inn or resting place for travellers. The station is named after the medieval village it was located in. The village itself was named after a sarai, named after Ruhullah Khan, a noble in the Mughal court. Once it was a sarai on the busy road to Delhi and pilgrimage town of Ajmer. He was one of the three sons of Khalil Ullah Khan, the Governor of Delhi province during reign of Mughal Emperor Shahjahan, and also a distant relative of Empress Mumtaz Mahal. Over time, this name has been corrupted to Rohilla after Rohillas who ruled a region called Rohilkhand around Bareilly and Rampur northeast of Delhi during the Mughal era. History Start Delhi Sarai Rohilla Terminal railway station was established in 1872 when the metre-gauge railway line from Delhi to Jaipur and Ajmer was being laid. It was a small station just outside Delhi as Delhi was confined to walled city then. All the metre-gauge trains starting from (and terminating at) Delhi (station code DLI) to Rewari, Punjab, Rajasthan and Gujarat passed through this station. The track from Delhi Junction to Sarai Rohilla Terminal was double. The single track from Sarai Rohilla to Rewari was doubled up to Rewari from where single tracks diverged in five directions. Gauge conversion Conversion of metre gauge to broad gauge started in 1991. The Delhi–Rewari railway line had double metre-gauge tracks and one of the tracks was converted to broad gauge in December 1994 as a part of conversion of Ajmer–Delhi line. Within a few years, both the tracks from Sarai Rohilla to Delhi railway station were converted to broad gauge and all metre-gauge trains stopped operating from Delhi station. As a result of this, all the metre-gauge trains terminated and started from Sarai Rohilla which became a railway terminus. By September 2006, the second metre-gauge track from Sarai Rohilla to Rewari was also converted to broad gauge and all metre-gauge trains stopped operating between Rewari and Sarai Rohilla (though the converted track was opened for public use only in October 2007).
