The author concludes that we can expect the volume of freight shipped by rail to increase. This is because railroads have had reduced operating costs, whereas the main competitor to railway shipping (trucking) is not predicted to have reduced operating costs.
The conclusion is the author’s prediction for what will happen to the volume of rail freight shipping: “[W]e can expect the volume of freight shipped by rail to grow.”

The volume of ███████ ███████ ██ ████ ███ ██ ████████ ██ █████████
This is a restatement of the conclusion.
Increasing reliance on ██████████ █████ ████ █████ ████████ ███████ ███ ███████
This is part of the support. Because fewer railroad workers are needed, the railroad industry has reduced operating costs. The author uses this support a prediction about an increase in the volume of rail freight.
No reduction in █████████ █████ ██ █████████ ███ ███ ████████ █████████
This is a premise. The author uses the lack of reduced operating costs in a competitor industry to support a prediction about the increase in rail freight.
Operating costs for █████████ ████ ████ ███████ ██ █ ██████ ██ █████████ ████████ ██ ███████████
This is part of the support. Because of the reduced operating costs, the author predicts an increase in rail freight.
The chief competitor ██ ███████ ████████ ██ ████████ ██ ██████
This is a premise. The author points out that rail’s chief competitor isn’t predicted to have reduced operating costs to support the prediction that rail freight volume will increase.
