Madurai junction is a well maintained railway station. However, there are few minor suggestions which can help the passengers.
1) Currently, there is only one foot overbridge and an escalator/descalator. So when a train arrives at a platform, people rush to exit the platform.
2) Please provide directions in the foot-over bridge such as "Meenakshi Amman Temple/ Ellis Nagar". This would be really helpful for the tourists.
3) Have a digital signboard in all the platforms informing the arrival and departure of a train with complete details such as train number, origin, destination, etc
4) Air-conditioned resting rooms for AC passengers similar to how KSRTC provides for its AC passengers in Shanti Nagar, Bangalore will be really helpful in the summer season.
