UPDATE 1-Higher freight rates lift CSX Corp's quarterly profit

(Adds details on freight volumes, revenues)

Oct 17 (Reuters) - CSX Corp, the third-largest U.S. railroad operator, reported a slight rise in quarterly net profit that met analyst expectations on Tuesday, on revenue lifted by shipment of coal and consumer goods and higher freight rates.

The Jacksonville, Florida-based railroad posted third-quarter net income of $459 million, or 51 cents per share, up from $455 million, or 48 cents per share a year earlier.

The results sent CSX shares up marginally in premarket trading by 22 cents to $53.06.

CSX has struggled with persistent customer complaints of service disruptions since the summer as its new Chief Executive Hunter Harrison worked to implement a controversial strategy overhaul to revamp the railroad's network.

The company's freight volumes were up 1 percent in the quarter, driven by 5 percent gains in both coal and consumer goods shipments which offset declines in almost every other commodity the railroad hauls, such as vehicles and fertilizer.

CSX's revenue grew 1 percent to $2.74 billion, from $2.71 billion, but was short of analyst expectations of $2.77 billion.

CSX reported an operating ratio, which measures operating costs as a percentage of revenue, of 68.1 percent, down from 69 percent. A lower operating ratio shows improvement in profitability and is a key metric for Wall Street. (Reporting by Eric M. Johnson in Seattle; Editing by Chizu Nomiyama and Bernadette Baum)
