New Delhi, Aug 10 - The opening of Delhi Metro's Noida Line that links east Delhi to the suburban Noida has been pushed back by a month due to the non-availability of trains, an official of the Delhi Metro Rail Corporation (DMRC) said Monday.

'The opening of Yamuna Bank to Noida Metro corridor is likely to happen only by the end of September 2009 as the new trains built for this line, which were being procured from Bombardier company, are still under commissioning and testing,' DMRC spokesman Anuj Dayal said.

The long desired and much awaited corridor that links the populous east Delhi to the suburban Noida in the National Capital Region (NCR) was due to be opened to public well before the deadline by August end.

Incidentally, the elevated stretch will also have to be cleared by the commissioner Metro Rail Safety before its opening, Dayal said.

After the July 12 Metro mishap, in which six people were killed when an under-construction beam collapsed in south Delhi, all Metro projects were closely reviewed and two cracks were found on piers on the Noida line.
