An article just posted online on January 25, 2009 by The Times of India reports on the success of the Konan Railway after 11 years of operation connecting Mumbai with Mangalore. In the article, they quote a press release from the Konan Railway saying:
Efforts have been taken to increase safety on the route by executing massive earthworks, widening slopes, planting vetiver grass to control soil erosion, and other geo-tech works to arrest boulder falls and soil slippage during monsoon. Major traffic disruptions were averted on the route in past three years since these works were executed and a special monsoon timetable implemented on the route.Konan Railway runs for 741 Km. and 564 rock cuttings constitute about 225 Km. of that. On the Konan Railway website, a document is posted describing their efforts on Geothech Safety. Extensive information on their commitment to Vetiver begins in page 14 of that document. Their commitment to good engineering and bio-engineering practices has been instrumental in reducing the number of boulder falls and soil slips from 132 in the year 2000 to 12 in 2008.
The Vetiver grass varieties used for soil conservation by the Vetiver System, come from the south of India. It is great to see that it still holds such a preeminent status in that country.
