In the other communication, the Chief Minister said the Railways' decision to drop the Nemom Coaching Terminal project was "a major setback to the rail infrastructure development of Kerala".
He said the project was first included in the Union Budget of 2011-12 and its importance was acknowledged by the Union Railways Minister while laying its foundation stone in March 2019.
Vijayan said landowners whose land was acquired for the project would be put to undue hardship.
"The Nemom Coaching Terminal project, which is proposed as a satellite terminal for trains departing from and terminating at Thiruvananthapuram Central, is essential for the development of rail traffic in the State. I request you to intervene so that the decision to abandon the above project is reconsidered and to ensure that an early approval is granted for the same," the Chief Minister said in the letter.
