Gurpa-Gujhandi

Once the rail link from Howrah to Delhi was completed in 1866, the East Indian Railway was making constant endeavour to reduce the distance of the Howrah–Delhi main line. After several surveys, one 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.[2]

The 22-kilometre (14 mi) Gujhandi (altitude 370 m)–Gurpa (altitude 193 m) section, 10 kilometres (6.2 mi) west of Koderma, is a ghat (mountain/hill slope), with the Koderma Plateau sloping down to the Gaya plain.[3]

The Grand Chord was opened on 6 December 1906 by Lord Minto, then Viceroy and Governor General of India with a function at Gujahandi.
