Alas, no. There are several longer. The longest of all, the Paijanne water tunnel in Finland, is a water supply tunnel so probably doesn't count. The Seikan tunnel in Japan carries a narrow-gauge railway and is 33.5 miles long. The Channel tunnel is certainly the longest full-size railway tunnel at 31.3 miles. However, those crafty Swiss are currently at work under the Alps, and the Gotthard Base tunnel (also a standard gauge railway) will be 35.5 miles long, a clear winner.
