Correct answer
Explanation
Seikan Rail Tunnel in Japan is 53.85 kilometers long and held the record as the world's longest railway tunnel from 1988 until 2016. The Channel Tunnel is shorter at 50.5 kilometers. Note: Gotthard Base Tunnel in Switzerland (57.1 km) opened in 2016 and is now the longest, but Seikan was correct when this question was likely written.
