Indian Railway finds fault with closed-doors system plan in Mumbai locals
The Western Railway was conducting trials in the second class ladies compartment of only one train. Senior officials from WR said that they have been testing it for several months now. Over a period of time, it has become obvious that the plan has serious flaws, including door’s opening and closing on time, poor ventilation inside, among others.

Despite there being forced ventilation inside coaches, it becomes suffocating during peak hours when more than 16 commuters per square metre travel per coach. Image source: Reuters
