The underground metro train Colaba-Bandra-SEEPZ made its way to the prestigious World Tunnel Congress. In actuality, just four of the 365 papers published came from India, and two of those four were on the Mumbai Metro's subterranean line.

The World Tunnel Congress is the ultimate international gathering of tunnel engineers. Projects involving difficult work are given the opportunity to be exposed to the world.

In September, the gathering took place in Copenhagen, Denmark. What is notable is that two of the papers made it, especially after a three-year hiatus, when the pressure is on to display one's project.

Projects from India, France, United Arab Emirates, Netherland, Brazil, Switzerland, United Kingdom, Sweden, United States of America, Italy, Austria, Spain, Australia, Czech Republic, Greece, Turkey, Germany, Japan, Egypt, Norway, Chile, South Korea, Canada, Iran, Thailand, Finland, Singapore and Argentina had representations made during the event.
