[4] Track doubling of the 130 kilometres (81 mi) long Gaya–Kiul line was announced in the Railway Budget for 2010–2011.

[5] To cater to the growing freight traffic, Cabinet Committee on Economic Affairs today approved the doubling of 124 km long Kiul-Gaya railway line estimated to cost Rs 1354.22 crore in March 2016.

Chaired by Prime Minister Narendra Modi, the CCEA decided in favour of doubling of this line which will ease the ever increasing freight traffic between the sections.

The project is likely to benefit Lakhisarai, Sheikhpura, Nawadah and Gaya districts of Bihar and is expected to be completed by 2022–23.

A special Memu train was flagged on 22 October 2018 by State Railway Minister Mr. Manoj Sinha.

Since Kiul is a terminal station for most of the trains, it does not have much significance as it is neither a great marketplace nor a tourist destination.
