(Reuters) -Railroad operator CSX said on Wednesday that employees represented by the Brotherhood of Locomotive Engineers and Trainmen (BLET) have voted to ratify the five-year collective bargaining agreement.

The contract, covering approximately 3,400 locomotive engineers, aligns with general wage increases, health and welfare improvements included in CSX's agreements with 13 other unions, the company said.

The union said in a social media post that the agreement was ratified by a 53.6% vote in favor by locomotive engineers, that, according to CSX, represent approximately 20% of its frontline workforce.

Jacksonville, Florida-based CSX said it now has ratified agreements covering nearly 75% of its unionized workforce to date.
