Bandikui is a city and a municipality in Dausa district in the Indian state of Rajasthan.

Bandikui was preferred for the tri-junction by British Railway surveyors over Rajgarh, Alwar, due to better alignment.

The first train in Rajasthan ran from Bandikui Junction to Agra Fort, started in April 1874 by the colonial government in India.

The city attracted migration from nearby villages and its population grew to more than 125,000.

It was in the reign of Lord Northbrook, the Viceroy that the Delhi – Bandikui line was opened in December 1874.
