The Delhi Metro Rail Corporation (DMRC) has begun the tendering process to identify a new fastening system — a technique for fixing rails to the concrete ties — for the tracks in Phase-III.

“The tendering process for the procurement of rails and turnouts has just commenced. At present,the specifications of the tender are being reviewed. The tender will be floated soon to finalise the technology for Phase-III,” a DMRC official said.

The DMRC was set to use RHEDA system for ballast-less tracks with Vossloh 300 fastening system in the 140-km Phase-III. The tender for a new track technology is being floated after the Railway Ministry rejected the technology. The ministry did this after flaws surfaced on the Airport Metro corridor,which uses a similar technique for its 22.7-km tracks.

The officials also said buffer stops of suitable design will also be procured by the track work contractors. Moreover,two contracts will be awarded for the execution of track work in Phase-III.

“ The track structure for Phase-III will be of the highest quality. The tenders for track execution works will also include the supply of fastening system for ballast-less track. The whole track on the main line,depots (where coaches are kept),including turnouts,will be joint-less or welded,” a Delhi Metro spokesperson said.

“Based on the bids,the new technology for the fastening system will be finalised in the coming month. The technology will conform to the performance criteria issued by Railway Ministry in May 2010.” he said.
