In what was construed as his offer to resign, Railway Minister Suresh Prabhu on Wednesday met Prime Minister Narendra Modi, taking full moral responsibility for train mishaps, after two successive train derailments in the last four days.

Prabhu wrote on Twitter that he takes full moral responsibility for the accidents and has met Prime Minister Narendra Modi in this regard. Prabhu tweeted that the Prime Minister had asked him to wait.

Earlier today, Railway Board chairman AK Mittal also tendered his resignation. Air India CMD Ashwani Lohani has replaced him.

Prabhu sought to explain his performance as the Railway Minister in the past three years under the leadership of PM Modi in a series of tweets:

“In less than three years as Minister, I have devoted my blood and sweat for the betterment of the Railways.”

“Undr leadership of PM, tried 2 overcome decades of neglect thru systemic reforms in all areas leading 2 unprecedented investment& milestones.”

“New India envisioned by PM deserves a Rlys which is efficient and modern. I promise that is the path, on which Rlys is progressing now.”

“I am extremely pained by the unfortunate accidents, injuries to passengers and loss of precious lives. It has caused me deep anguish.”

“I met the Hon’ble Prime Minister @narendramodi taking full moral responsibility. Hon’ble PM has asked me to wait.”

On Saturday, the Kalinga Utkal Express, travelling from Puri to Haridwar, had derailed at Khatauli near Muzaffarnagar killing 22 people and injuring over 150 others. Fourteen bogies of the train had derailed allegedly due to repair and maintenance work being carried out on those tracks at the time.

The Government Railway Police began an investigation into the derailment with its personnel visiting the site and talking to locals about the accident.

On Sunday, the railway ministry sent on leave top officials including a member of the railway board for the Utkal Express derailment.

Stung by the accident and criticism of opposition parties, the ministry sent member (engineering) railway board Aditya Kumar Mittal, general manager (GM) Northern Railways RK Kulshrestha and divisional railway manager (DRM) RN Singh on leave till further orders.

Early Wednesday morning, in the second incident in four days, nine coaches of the Kaifiyat Express derailed near Auriaya leaving over 70 injured, four of them seriously. The Railway Ministry said in a statement today: “An unauthorised dumper broke the railway fence and hit the engine of Kaifiyat Express causing derailment. There are no casualties.”

According to railway officials in North Central Railway (NCR), the collision happened around 2.40 am between Pata and Achhalda railway stations. While eight coaches have been derailed, one coach overturned due to the massive impact of the collision. “An unauthorised dumper broke the railway fence and hit the engine of Kaifiyat Express causing derailment,” the Railway Ministry said in a statement.

As per a PTI report, at least 53 per cent of the 586 train accidents in the last five years were due to derailments with the Utkal Express derailment being the latest. Notwithstanding the railways’ attempts to upgrade the safety apparatus, many such accidents continue to occur. Over 20 people died and 97 were injured after 14 coaches of the Utkal Express derailed near Muzzafarnagar in western Uttar Pradesh on Saturday evening.

According to official figures, of a total of 586 rail accidents in the last five years, nearly 53 per cent were due to derailments. Since November 2014, there have been 20 rail accidents, many of them minor.

There have been over 20 rail accidents, including minor ones, since November 2014, when Prabhu took office. The total count of “consequential accidents” since 2014-15 stands at 346 accidents. In at least nine of these cases, casualties were reported.
