LOUISVILLE, Ky. (WDRB) – By early September, more trains are expected to move between Louisville and Seymour, Ind., as part of a $100 million rail line improvement project.

Trains operated CSX Corp. also plan to travel at speeds up to 49 miles per hour between the two cities – nearly double the current speed limit.

The Jeffersonville, Ind.-based Louisville & Indiana Railroad Co. and CSX outlined those details in a public notice to be published in regional newspapers in the coming days, part of a requirement set by federal regulators who approved the project in 2015.

Under the deal, CSX will make improvements to more than 100 miles of track between Louisville and Indianapolis owned by the Jeffersonville railroad. CSX has until 2022 to complete the privately funded work.

Workers are replacing older tracks with a modern line that will allow individual cars to carry 18,000 pounds of additional freight, according to filings with the U.S. Surface Transportation Board. With a stronger rail line in place, CSX can move more freight through Indiana to destinations in the upper Midwest.

CSX, which runs three to four trains on the route now, says in the notice it plans to eventually move at least 10 trains per day along the line between Louisville and Seymour. Some trains may be 14,000 feet long.

Existing rail traffic also is expected to change as some trains now using a Louisville-Cincinnati route travel north through Indiana.

In the metro area, the railroads predict average delays for drivers will more than double at crossings in the Algonquin and California neighborhoods. Projections call for more trains to use 16 rail bridges in Louisville.

Despite concerns about faster trains carrying potentially dangerous chemicals and the state of aging overpasses near the University of Louisville’s Belknap Campus, the project has the backing of the mayors of Louisville and Jeffersonville, the Jeffboat shipyard and the Ports of Indiana, which stands to benefit from the modernized rail line.

L&I President John Goldman said signs have been placed near intersections that will see more train traffic. In addition, he said has met with local leaders about the changes coming to the rail line.
