In another train derailment incident, one coach and engine of the Ranchi-Delhi Rajdhani Express derailed today in Delhi.
There was no report of any injury in the mishap, Railway ministry spokesperson Anil Saxena said in New Delhi.
The Ranchi Rajdhani derailment takes the number of such incidents to four within the past 30 days - and the second since Prime Minister Narendra Modi chose to appoint Piyush Goyal as the new Union railway minister.
The injured man, identified as Imam Hussain, was taken to Lok Nayak Jai Prakash Narayan Hospital in Daryaganj, Sharma added. No injuries were reported in this derailment.
The first derailment occurred around 06:25 am, when seven coaches of Jabalpur-bound Shaktipunj Express jumped the tracks near the Obra Dam station in the Sonbhadra district of Uttar Pradesh, in third such mishap in the state within a month.
At least two wagons of a goods train derailed near Khandala in Maharashtra on Thursday, making it three derailments within 12 hours on the country's vast railway network. All the passengers were reported to be safe and no one was injured in the incident.
Platform number 15 at the Delhi station was closed for restoration work, a railway official said. Days later - on August 23 - the Delhi-bound Kaifiyat Express collided with a dumper and went off tracks in UP's Auraiya district, injuring over 100 people.
Newly appointed Railway Minister Piyush Goyal personally monitored the situation after the derailment of Shaktipunj Express.
