RJD national president Lalu Prasad and Union minister Ram Vilas Paswan expressed grief over the loss of six lives in the derailment of Delhi-bound Seemanchal Express in Bihar's Vaishali district on Sunday.

Prasad, who was railway minister in the UPA-I government between 2004 and 2009, is serving sentences in fodder scam cases and currently lodged at a hospital in Ranchi on account of ill-health.

Union minister Ram Vilas Paswan, who represents Hajipur in the Lok Sabha and has held the Railway portfolio in the past on more than one occasion, also mourned the tragedy.

"The accident is tragic. Condolences to the affected families. I am in constant touch with the chief minister of Bihar, the railway minister and the district administration to take stock of the relief and rehabilitation work," Paswan said in a tweet.

The accident took place at Sahdei Bujurg, about 25 km from Hajipur town. Paswan, the Union minister of consumer affairs, food and public distribution, represents Hajipur Lok Sabha constituency.

A release issued by Paswan's Lok Janshakti Party said Paswan had left for the site of the accident that took place around 4 am.

He deferred his visit to the site, which falls in his parliamentary constituency, "so that relief work is not affected on account of protocol", the release said.

Bihar Deputy Chief Minister Sushil Kumar Modi said in Patna the Patna Medical College and Hospital (PMCH) has been instructed to reserve at least 20 beds for the accident victims.

"I would also urge the workers of the Congress party, which is holding a rally in the state capital later in the day, not to hamper movement of ambulances," he added.

Congress president Rahul Gandhi is scheduled to address the "Jan Akanksha Rally" in the afternoon.

He also came out with tweets expressing grief over the rail mishap.
