Such facilities world over are very difficult to run profitably directly from the revenues from the specific facility but atill they are essential. essential because whatever u run the roads will be effected by traffic jams and in course of time as volume of traffic increases the speeds will decrease. but in case rail networks the speed remains more or less the same and yet u can transport greater number of ppl by increasing the frequency. these facilities therefore repay increase the overall business potential of a place and not directly through revenues.
