Railway staff beware. Railway Minister Laloo Prasad Yadav will be travelling incognito to make on-the-spot assessment of passengers' problems.

The alert was sounded by Yadav to his officials when he paid a surprise visit to the New Delhi railway station late on Wednesday night.

During his visit, the minister noticed certain 'infirmities' in the maintenance of the station premises and instructed the officials to maintain the desired level of all-round upkeep of the station, an official release said.
