The Palwal-New Delhi-Ghaziabad train went off the track at around 9:45 this morning. There have been no reports of injuries or deaths.
"Only one wheel came off. The passengers of the derailed MEMU (mainline electrical maintenance unit) were taken onwards by another train," said Nitin Chowdhury, the chief public relations officer or CPRO of Northern Railways.
He added that the divisional railway manager and other senior officials reached the spot soon after the incident.
The reason for the wheel coming off is being investigated, he said.
Thirteen coaches of the Vasco Da Gama Patna Express had derailed near Manikpur in Uttar Pradesh, killing three people and injuring nine.
In the second derailment, a Paradeep Cuttack goods train jumped the rails between Goraknath and Raghunathpur in Odisha.
