kuch nahi milta isliye richest hai; for every passenger train you put on line (which mostly are loss making) you remove the opportunity to run a super profitable freighter.
this trend is, unfortunately present across IR, the line which give the maximum revenue are the ones along which passengers suffer.
NCR and SCR somewhat buck this trend by having a decent proprotion of both (and having very good OR) but it leads to trmenedous pressure on the major junctions like ALD and BZA. same in WR, where BRC faces the brunt of traffic...
more... but manages it quite well.
