What percentage of freight is moved by rail?
Heavy freight such as coal, lumber, ore, and heavy freight going long distances are likely to travel by rail, or some combination of truck, rail, and water. The rail network accounted for approximately 28 percent of U.S. freight movement by ton-miles (the length and weight freight travels).
How many cars do freight trains pull?
Depending on track gradient and other constraints such as the lengths of passing loops, loading and discharge loops and sidings, these trains can vary from 40 to 46 wagons. So each loco can pull 20 to 23 fully loaded wagons in typical operating conditions.
Is rail more efficient than road?
Rail transport, with hard steel wheels on steel rail, has lower resistance to motion than road transportation. Passenger rail is around three times more efficient than a car on a passenger-mile basis at current occupancy levels. The lower energy consumption leads to lower greenhouse emissions.
How much freight is moved by rail or truck?

How do freight trains pull heavy loads?
Locomotives can pull massive weights due to these bad boys. Hydraulic dampers, essentially large springs. There are springs behind the disk shaped things, and also behind the hook. Its to cushion the forces.
What is the average speed of a freight train?
The average speed for most trains today is between 30 and 50 miles per hour. The fastest speeds are attained by specially built railcars that travel between 100 and 150 miles per hour. If the train carries cargo and has no cars attached, it can go as fast as 60 miles per hour (mph).
What are disadvantages of rail transport?

- Lack of Flexibility:
- Lack of Door to Door Service:
- Monopoly:
- Unsuitable for Short Distance and Small Loads:
