What is the longest railroad in the world?

Is the Trans-Siberian Railroad the longest railroad system in the world?

• Answer:

  No, Trans-Siberian runs the world's longest passenger train service, but they don't have the largest track network. I don't have specific data for you, but the country with the largest track network is the United States, and the largest railroad company in the U.S. is UPRR. The following countries are Russia, Canada, China, and India. Although India has the fifth-largest rail network, all their rails are owned by a single national company, making it the largest railway network in the world under a single ownership.
