I think Railways are definitely coming up with general second class AC coaches too this year.
Along with WL pax there is the usual nuisance created by short distance commuters too who travel in long distance trains reserved coaches. That's why I even mentioned in my solutions IR should stop running white elephants and use the free slot for running new trains or increase frequency of existing ones. Capacity enhancement of railways is also a long term solution. But people should also change their mentality if you don't get a confirmed ticket in train then they should not travel or use alternatives if it's urgent.
