Ghaziabad, Nov 7  Four railway workers working on tracks were killed after being run over by the Dehradun-Delhi Jan Shatabdi Express in Ghaziabad Saturday, an official said.

The accident occurred at around 11.10 a. m. "They were doing maintenance work on the tracks," Anant Swarup, chief public relations officer of Northern Railways, told IANS.

Swarup explained that trains are normally stopped for maintenance work on the tracks, but for some reason this train did not stop. He said the train had reached Delhi and its driver was being interrogated.

The driver has reportedly said that he did not see the workmen due to the fog that drastically cut visibility. (IANS)
