Carload freight would be too much to handle in most areas of NYC. Big businesses that used to handle freight car loads have long since gone. Not many businesses take more than a hand truck load of freight. What would make more sense for the alleviation of traffic congestion would be to ban truck deliveries in the city until after the end of rush hour 7PM to 6AM. In NYC, rush hour is really from 6AM-9AM and 3PM-7PM. A large source of traffic congestion is double parked trucks both tying up traffic and blocking in parked cars.
