As i am seeing more and more Diesel supported engines(DEMU) and not Electric supported (EMU) it will create many problems for you also the poor condition of railways is to do with fact of Power shortage in Pakistan which leads to Railways deterioration. That is also another problem for railways.
I will tell tell you my view as being a entrepreneur i will look at the transportation and flow of goods cost in a country for setting up my manufacturing facility so that i should be able to compete with other competitors in field in terms of price of my product because how can i bear a very expensive transportation cost to sell my product in accordance to the price of the same product with other competitors. My competitors will have advantage over me in terms of cost of product and I will bear heavy loss. As far as you there is so much investment flow in India in the past 1 year is that it has sufficient infrastructure to support goods transportation and flow of goods with cheap logistics and transportation cost. After the completion of DMIC INDIA will become cheapest place to do business leapfrogging even USA. I will tell you as per sources many companies are on the verge of finalizing land for their manufacturing facilities as you can see the project has not even gone past phase-1 but still much urgency for companies in DMIC.
