Train services in central Kerala, including routes near Chengannur, were significantly affected as Southern Railway commenced critical maintenance and renovation work on Railway Bridge No. 128 on the Mavelikara–Chengannur section. The track work, planned for late November, led to diversions, cancellations, and temporary regulation of several trains to facilitate safe and efficient construction activity. Passengers were advised to check updated schedules before planning travel.
Several long-distance trains that normally run via the Kottayam corridor were diverted through Alappuzha during the construction period, skipping their usual stops. This included major express services connecting Thiruvananthapuram with Chennai, Bengaluru, Mangaluru, and other destinations. The diversions aimed to maintain connectivity while allowing uninterrupted bridge work.
In addition to full diversions, some trains experienced temporary regulation and delays, with services such as the Kollam–Ernakulam MEMU, Palaruvi Express, and Vanchinad Express being held for around 30 minutes en route to manage traffic and ensure safety during construction hours.
The bridge maintenance work is part of ongoing efforts by Southern Railway to upgrade track infrastructure and enhance safety and operational efficiency across the rail network in Kerala. Residents and commuters in and around Chengannur were urged to stay informed about revised timetables and possible changes to scheduled services.
Passengers were encouraged to consult official railway notifications and station announcements for the latest updates and alternative travel arrangements, as the renovation work is expected to continue impacting rail movements in the region.
