The Tomah Subdivision or Tomah Sub is a railway line that runs about from La Crescent, Minnesota in the west to Portage, Wisconsin in the east. The line is operated by the Canadian Pacific Railway's through its subsidiary, the Soo Line Railroad. The line crosses the Mississippi River between La Crescent and La Crosse, Wisconsin. Junctions in La Crescent lead to the River Subdivision to the north and the Iowa, Chicago and Eastern Marquette Subdivision to the south. In the east, the rails continue as the Watertown Subdivision. Interstate 90 runs roughly parallel to the rail line. Most of this segment of track was quickly built over the span of two years. The line was completed from Portage to New Lisbon in 1857, and from New Lisbon to La Crosse in 1858. It took several more years for the crossing of the Mississippi River into Minnesota to take place, but that was finally completed in 1866. The Tomah Subdivision had previously been operated by the Chicago, Milwaukee, St. Paul and Pacific Railroad, though Canadian Pacific took it over when the Milwaukee Road folded. In 1935, the Milwaukee Road introduced the ''Hiawatha'' passenger train which ran at high speed between Saint Paul, Minnesota and Chicago, Illinois. A timing from February 2, 1939 measured the train (pulled by a powerful class F7 locomotive on this run) traveling at or above for at least 20 miles along this stretch. For a couple of miles, it hit . In the future, it would run even faster, since this was a few months before the Chicago–Saint Paul schedule was shortened by 15 minutes to make the run in 6 hours 15 minutes. Today, the Amtrak ''Empire Builder'' uses this stretch of track, but is limited to . Along this segment it stops in La Crosse, Tomah, Wisconsin Dells, and Portage. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tomah Subdivision」の詳細全文を読む スポンサード リンク
