The '''Gaya–Pandit Deen Dayal Upadhyaya Junction section''', formerly '''Gaya–Mughalsarai section ''', is a railway line connecting [[Gaya Junction railway station|Gaya Junction]] and [[Pandit Deen Dayal Upadhyaya Junction]]. This {{convert|197|km|adj=on}} track is part of the [[Grand Chord]], [[Howrah–Gaya–Delhi line]] and [[Howrah–Prayagraj–Mumbai line]]. This section includes Arrah-Sasaram and Son Nagar branch lines. It is under the jurisdiction of [[East Central Railway zone|East Central Railway]].

==Grand Chord==
Ever since the railway connection of Delhi with Howrah in 1866, the [[East Indian Railway Company]] was making regular efforts to reduce the distance of the [[Howrah–Delhi main line]]. After a survey in 1888-89 and two more subsequently, a route was determined from Dhanbad to Mughal Sarai via Koderma and Gaya. The major works in this section were a bridge across the [[Son River]] at [[Dehri]], and tunnelling and ghat line construction between Gurpa and Gujhandi.<ref name=grandchord>{{cite web| url = http://eastrailindia.tripod.com/grandchord.html |title = As the traffic continued to grow even beyond the capacity of the | publisher=Tripod |access-date = 20 November 2011 }}</ref> The Grand Chord was opened in 1907. Even when the Grand Chord was under construction, the Son Nagar-Daltonganj branch line was opened in 1902.<ref name=timeline>{{cite web|first=R.
