@xavierdatatech While the reactions here lament how we in the West run our trains, It is in my opinion that we will never have such an efficient and smooth operating rail system over here. It requires more than demand and money alone, namely a culture change. We cannot have nice things here with rampant vandalism, individualism (people as well as countries/states) and ultra capitalistic society. Sadly I just don't see it happening.
