Line 1 will run 11 km underground from Delhi University at Vishwavidyalaya in the north to Central Secretariat in the south, serving 10 stations. Line 2, the first 25 km surface/elevated route, will link Shahdara in the east to Nangloi in the west via Subzimandi and Tri Nagar. Line 3 was intended to run 19.3 km from Subzimandi to Holambi Kalan, but as this parallels an existing Indian Railways (IR) line, the government is considering whether to build a 16-km route from Tri Nagar to Barwala instead. Tenders are currently being evaluated for construction of Line 1 (underground), and the winning contractors should be announced later this year. Firms shortlisted for the project include Kumagai Gumi, Kajima Corp. and Obayashi of Japan, Skanska AB of Sweden, and Dywidag of Germany.

The Joint Venture MeCtNord, composed of Webuild and Impresa Pizzarotti & Spa, have contracted to CRCHI, TBM Technology and Anbel the supply of a TBM EPB - 9.36 m diameter- to be used to excavate the 12.5km tunnel for the Giampilieri- Fiumefreddo railway, lot 2 Taormina-Giampilieri, on the Messina-Catania line, Sicily. These tunnels will cross weak rock formations with highly variable characteristics and behaviors along the route, that will require a frequently change to the operating mode, from close mode to open mode.   

Therefore, the TBM will have such characteristics as to be able to efficiently excavate long sections in the rocks, with cutter thrusts and cutter-head revolution speeds higher than the usual range of a standard EPB TBM.  Visit https://www.webuildgroup.com/, https://www.pizzarotti.it/, https://en.crchi.com//, https://www.tbm-technology.com/ and http://www.anbel.com/. 20/23.
