I was just going through the Rabindranath's poems and I kind of paused on this line. When time is considered as wealth, we all have predecided-limited savings and simply because we are unaware of its exact amount, we afford being late.
In light mood, Mumbai subarban railways are almost always late which implies they are affluent. If we consider affluence in terms of INR, then they should increase the amenities and if in terms of time, then they should increase the frequency :)
