Which is the longest railroad line in the world?

• A. Canadian Pacific Railway
• B. Orient Express
• C. Baltic Line
• D. Trans-Siberian Railroad

Answer: (D)

Long-distance rail lines are measured by the distance of a single continuous track from end to end. The Trans-Siberian Railroad fits this idea, running from Moscow to Vladivostok across Russia and covering about 9,300 kilometers (roughly 5,800 miles). It crosses vast swaths of Siberia and spans eight time zones, making it the longest continuous rail route in the world. The Orient Express is a famous luxury service that has used various routes over time and isn’t one uninterrupted line across that many kilometers. The Baltic Line isn’t a standard long-distance route, and the Canadian Pacific Railway’s main cross-Canada path, while long, is shorter than the Trans-Siberian. So the Trans-Siberian Railroad is the longest.
