The environmentalist further raised concerns about the CPI(M)'s seemingly contradictory stance, since it is opposing a similar high-speed rail project from Mumbai to Ahmedabad.

"The Mumbai-Ahmedabad bullet train is being staunchly opposed by the CPI(M) in that region and they took out a long march against it. There are articles in People's Democracy,

their own mouthpiece, which is criticising this project. The same government is now promoting the Silver Line project, which is a similar project, in Kerala," Sridhar Radhakrishnan

said.
