In my view the Biggest fault was rake standardisation ( reduction of sleeper and general and increase of 3E/3A).Even if there was a plan to do it, it should have been done slowly and at least experimented with overnight trains for short journeys instead of doing it for long distance trains across the country. The long distance trains especially route carrying migrant workers and routes with lots of rush there was no need to do standardisation at all. It was a big mistake
