Hump operations at a third CSX yard are set to close. This time it is Osborn Yard in Louisville, Kentucky.
Flat switching will continue at Osborn Yard, which is a former Louisville & Nashville facility located south of downtown Louisville.
A CSX spokeswoman said the moves are part of an effort to make rail operations more efficient by enabling workers to more quickly process trains.
She said five jobs will be eliminated but Osborn will still have 470 employees.
Osborn is the hub of rail lines from Indianapolis; Evansville, Indiana; Cincinnati; and Nashville, Tennessee.
