Just recalled the existence of this thread. Gonna repost this here from MVTD thread, which is where I previously posted it: Delhi Metro Rail Corporation releases report with an express recommendation that linear motor propulsion be used on a new light metro line to be built in the city of Thiruvananthapuram.
New DPR finds Light Metro ‘viable and socially justified’

New technology suggested in report will reduce costs

The Delhi Metro Rail Corporation’s (DMRC) reworked Detailed Project Report (DPR) for Light Metro in the cities of Thiruvananthapuram and Kozhikode has found the project ‘viable and socially justified’ and that it has the needed ridership.

The DPR was revised as per the parameters of Metro Rail Policy-2017 under the supervision of Principal Adviser, DMRC, E. Sreedharan and is awaiting the government’s nod since November 2017. The Financial Internal Rate of Return (FIRR), an indicator to measure return on investment, based on the revised costs and additional revenues, for Thiruvananthapuram has gone up to 7.24% and 8.66% for Kozhikode.

The reworked Economic Internal Rate of Return (EIRR), a tool for advocating investments, has gone up to 17.25% for the capital city’s project and 17.61% for Kozhikode. “It is comfortably above the datum base of 14% indicated in the Metro policy and the two projects are socially justified,” says the DPR.

Another significant change is the recommendation for the Linear Induction Motor (LIM) technology for the rolling stock to negotiate sharp curves up to 60 m and a steep gradient up to 6%. The use of LIM technology will reduce the axle load to 9 tonnes leading to about 4% savings in civil structures and track costs along the 35.12-km corridor in the two cities. There will be considerable savings in the operation and maintenance costs.
