Railway should impose heavy fine on too much luggage people taking on railway, plus reduce weight of carriage. use fibre body one which will reduce weight and fuel requirement. These simple techniques might save lots of energy for Railways. Some sort of aerodynamic wind flowing mechanism should be used instead of having 5-10 fans running in each compartment of a coach. (not an engineer just a thought propped up in mind)
But the problem is weighing/measuring each piece of luggage. We will need airport style check in counters for it. Can't be done in the present setup.
The fans are ok, if anything, there isn't enough ventilation in the trains.
If you read the article fully, it states that the railway actually makes a profit on the popular classes i.e. AC chair car and AC 3 tier. These passengers (including myself) are going to be the hardest hit, having to pay for the sleeper and general class passengers' subsidy.
