Relative to the person pushing the box the frictional force is opposite to direction of travel but relative to a person standing next to the train the frictional force is the same direction as the box is travelling. Since motion is relative then yes friction can point in the direction of motion. This would only work if the thing that is causing the friction is moving in the opposite direction to the force pushing the object. An example is a person pushing a heavy box from the front to the rear of a fast moving train.
