Train traffic on a rail line between Louisville and Seymour will increase starting around Sept. 1.

The Courier-Journal reports that the current speed of trains on the line will increase incrementally over several weeks from a current maximum speed of 25 miles per hour to a speed limit of 49 miles per hour. In turn, the number of trains will increase from three or four trains per day, to around 10.

CSX Transportation officials say that the length of the trains may also increase.

CSX Transportation spokeswoman Laura Phelps reportedly stated that the federal Surface Transportation Board approved an agreement between the Louisville & Indiana Railroad and CSX in 2015 that gives CSX a permanent easement to operate over the railroad’s 106-mile corridor between Indianapolis and Louisville.
