Yes we built indias massive railway network, which was the worlds largest/longest for a long while(even though they only like focusing on the nad things we did). Also note that we were the ones who invented railways in the first place and we actually built even japans first railway .
Though now the japanese are ahead of us.
However its strange to see the Indian governnent hasnt achieved/changed much from our old railway system we built over a century ago when we were ruling india.
Cant even begin to imagine which railway india will have at all if we didnt build their long railways system they have today. Modi does have a lot of job to do. But i think he can do it, since he is very pragmatic andand less paranoid about china or other countries as fr as it comes to business.
So cooperation,investment, discipline, reform, new work ethic,planning and implementation will be key for india railway.
