My personal view is that slowly we should get rid of non-AC classes. Most developed railways have got rid of non-AC coaches , primarily because they cause too much drag and also in a country having hot weather like India, those aren't exactly humane conditions to travel in, especially in summer. So it's good that IR is moving in the right direction. In terms of fares, you are right, the fares should have increased by the same percentage as the increase in Per Capita Income, but in govt departments, politics takes precedence and how we have IR increasing fares through the backdoor, which is unfortunate but that's what we get for supporting populist politicians.
