Ernakulam-Mulanthuruthy-18km doubling was completed a few months ago. Still speed is restricted in this section, where cut and connection occurs.
Mulanthuruthy-Kottayam sector even does not have started the doubling work. Surveys are still pending.
Kottayam-Chengannur also the same situation. Chengannur-Mavelikara work is very slow, Mavelikara-Kayankulam is in the final stages.
