Ernakulam North, Perumanur (later closed), Mattanchery Halt and CHTS were the newly opened stations on the route.

In 1946 the station was converted into broad gauge as part of the Shoranur–CHTS line, linking it directly to the rest of India via the Mangalore–Jolarpet mainline at Shoranur Jn.

[10] As the coastal line to Alappuzha was opened in 1989, Ernakulam Junction rose to the status of the most premier railway station in central Kerala.

The renovation entails the erection of multi-story structures spanning a total built-up area of roughly 62,000 square metres on the station's eastern and western faces.

A ticketing area, waiting lounges, and commercial space will all be housed in the renovated West Terminal structure.

It does have all amenities expected out of a major junction including a paid air-conditioned lounge with free Wi-Fi, a library, rest room, children's play areas etc.
