1) At Ambattur morning 8.30am and 8.32 am two EMU towards beach - first one general ; second one ladies special mostly empty. Afterwards a long gap for train to central.

Suggestion : Merge these into single trip .More coaches in the same train to be allotted for ladies.
2) Evening return from 6pm to 9.30pm at central trains are over crowded.
Suggestion: Reduce halting time of sub trains at Central.Bring shuttle service upto perambur.So that train from beach will share the load from perambur.

3) At Suburban central station entrance police block more space for security checking.This creates bottleneck for the flood of outgoing passengers.
Suggestion: Artificial block is created by police in order to receive some VIP police officer at suburban central station entrance every morning at the cost of inconveniencing commuters.Allot less space for these security checks.

4) Bottlenecks for commuters crossing sub way:
a) Prime car parking blocks more space - restricting public movement.Has any politician has taken contract?The urchins there block poor commuters from crossing thro this area.
b) Poorly maintained park adjoining subway-in front of central is depository of nightsoil creating bad odour.Demolish the petty shop on the head of subway.Open the park as entry for subway.Also make the subway broader.Remove old ambassador taxis parked.They form a cartel in blocking free flow of commuters.Police help them in putting barricades.
