The death toll from a train derailment at the NCR Railway track on Monday has risen to 2, the railways said.
The accident took place in the vicinity of Kishan station, about 40 km (25 miles) from Delhi, about 1 hour after it started.
The railway said the train was traveling on the Naxalite-Jaipur Express line, connecting the two states.
The derailment happened about 30 minutes after it had left Jaipur for Kishonpura, the railway said.
A total of 4 people were injured.
The railway has been conducting regular train checks since the incident.
On Sunday, police arrested the man suspected to have been responsible for the derailment.
The National Capital Region Railway Board has ordered an inquiry into the incident and will submit its report to the state government on Tuesday.
The NCR has been operating under the National Capital Territory of Delhi Act since 2000, making it the oldest railway in India, running trains from Jaipoor to Delhi.
