Son Nagar Junction is a railway station in Aurangabad district. It serves Barun and Daudnagar towns of Bihar.[1] It is located on the east bank of the Son River and was earlier known as Son East Bank.
The Upper Soane Bridge, connecting Son Nagar and Dehri-on-Sone across the Son River, was completed in 1900. The 3064m (10,052feet) bridge was then the longest bridge in India. Work on the Grand Chord line of East Indian Railway was completed in 1901. It was formally inaugurated in 1907.[2]
A branch line was opened from Son East Bank, as Son Nagar was then known, to Daltonganj in 1902.[2]
Son Nagar is expected to be connected with Ludhiana as part of the Eastern Corridor. The primary feeder routes for this will be from Son Nagar to Durgapur via Gomoh, Son Nagar to Tatanagar via Garhwa Road, and Barkakana to Bokaro via Chandrapura.[3]
