Directly comparing the operating cost as fuel is not appropriate here. First, 0.25 km/l is the most efficient figure. The running consumption will be quite high. Secondly, there are various fixed costs involved. How do you think that the wagon manufacturing cost will come from. So, the fixed cost is distributed over number of trips so as to recover break-even point. Third, cars are not transported by driving them from one place to another. Along with petrol, one need to employ lots of drivers which again bring more cost with it. Till recent years, only truck transport was available. My dad bought a car and it was transported from Pune to Bhilai which is maybe around 1000 kms. And he paid 20k for this.
