There were two separate railway stations called Dehri-on-Sone and Dehri – one for narrow gauge Dehri Rohtas Light Railway and one for the Grand Chord Line.During British period, the Dehri on sone, station was called "Sone east Bank" by East Indian Railways [EIR].The two railway stations had no rail link because of the gauge difference and were separated by a road called Station road.

Etymology and History[edit]

Dehri is a very old town and was prime camp on The Grand Trunk Road (earlier called Sadak-e-Azam during Mughal times, now called the "Old G.T. Road" or "Sher Shah Suri Marg"). During the British Raj, soldiers on its way from Calcutta to Delhi used to cross the Sone and usually rested at a place near the present town now known as Parao meaning camp or halt in Hindi. It is also said that the name Dehri has been derived from the word "Dera" meaning basetown or camp in Hindi and Urdu. It was also known for its mild climate during autumn and spring. Noted Bengali Novelist Sharat Chandra Chattopadhyay wrote his famous novel Grihadaaha in the town while he was on vacation. Dehri High School is one of the oldest secondary education centres in Bihar, established by the British for western-style education.

Closure of the industrial complex[edit]

Dehri owes much of its prosperity to the Dalmianagar Industries. "Dalmia Industrial Estate" in Dehri boasted a housing colony, gardens, clubs, schools and market complexes for its employees. Rohtas Industries had their own private aircraft in those days and a small air-field at Dehri.

The prosperity of Dalmianagar started to decline in the mid-1970s as the law and order situation in this industrial town began to worsen. Workers were provoked to go on strikes for political reasons. Slowly, executives and professionals began to leave and the factories were mismanaged. By the mid-1980s factories started to shut down. Massive State Electricity Board bills remained unpaid by Rohtas Industries. There were irregularities in payment of salaries and wages to employees. By the 1990s, Dalmianagar was deserted.The famous,girls high school, and Dalmianagar higher secondary school, which were established and run by the Rohtas Industries gave the best result in the Board exams.The earstwhile students were holding the best position in the country, outside world also.

Thus together with the unemployed registered with the local Employment exchange numbering 3,28,839, the total number of workers seeking employment as in June, 1987 added up to 3,41,024. The situation further worsened when thousands of people who were earlier engaged in ancillary industries in some form or the other also lost their job.
