Railway operator Norfolk Southern today kicked off a daily rail service for moving cargo between Charleston and S.C. State Ports Authority’s new rail yard in the Upstate, officials said today.

The train service allows companies to transport shipping containers to and from SPA’s so-called inland port, a nearly 100-acre facility that opened weeks ago near Greenville-Spartanburg International Airport.

The inland port is a nearly $50 million project with costs shared between SPA and Norfolk Southern.

Train service to and from the facility runs once each day between Monday and Friday, according to Norfolk Southern’s website.

The company’s cargo service departs from Norfolk Southern’s rail yard in North Charleston in the early evening. The train travels more than 200 miles to Greer within seven and a half hours, according to Robin Chapman, a spokesman for Norfolk Southern.

He added that the new service will use existing staff and rail lines.

Norfolk Southern previously offered sporadic rail service between Charleston and Greer, Chapman added.

The SPA has said the inland port will help grow cargo efficiency and lessen the number of trucks on state highways. Agency officials have said the inland port will trim 25,000 truck trips each year from state highways.
