The recent derailment near Asangaon station due to breakage of pantograph the equipment connecting overhead cable that supplies electricity to local trains has left the railway authorities scratching their heads.

Officials at Central Railway (CR) are enquiring to ascertain how the pantograph from a local train collapsed on the tracks on Friday that led to derailment of two coaches and engine of Faizabad-LTT Saket Express.

According to sources in CR, the pantograph belongs to Siemens trains that came into operation from 2007. The enquiry, therefore, is not just about the question of maintenance of trains, but also about the newer trains in operation on the suburban line.

These trains were procured by the Mumbai Rail Vikas Corporation, on behalf of railway authorities and manufactured at the Integral Coach Factory in Chennai. “The enquiry should bring to light whether there was an issue of maintenance or if the problem budded from the start,” said a CR official.

The enquiry will look into aspects like alignment of overhead equipment, if it was uneven, and whether the pantograph and other equipment were not maintained properly or if the issue was with the fitting.

Going off track
