Complaint Description :
The Madras Park (MPK) railway station is one of the highly patronized railway station in Chennai Division. The ticket counters are situated in Platform #1 Beach side line. To goto Platform #2, passengers have to climb steep FOB which is in a dilapidated condition with edges of many steps broken. People arriving at Chennai Central with huge baggage find it very difficult to climb. Hence many people risk their life by jumping into the track to cross the plafrorm. The railways if it installs a Way Up escalator in platform #1 and a Way Down in Platform #2, it would be highly helpful.
Closing Remarks:
Feasibility will be examined for provision of escalator/lifts at the station. Thank you for bringing this to the native of Railway Administration.

Agreed with the point that it is tough, i used to face the same every time. But taking risk by jumping to track is never a solution.
Alternatively, you can move towards Chennai Beach side end of Chennai park station and cross the track. This is best alternative because, you are not jumping into the track and also, local trains will come and stop before that point. So there is zero chance of taking risk(only if you risk yourself crossing when train is about to start from park).

shortcut, you will have do little bit of walking. But effort will be less compared to climbing of stairs at the same time and also less risk to your life.
Lets hope they come with escalator soon.
