Passage Summary: Because trains are becoming cheaper to run through automation while trucks are not, we can expect more goods to be shipped by train in the future.

Conclusion: The volume of freight shipped by rail is expected to increase.

Reasoning: Increased automation has lowered operating costs for railroads, while no such cost reductions are expected for their main competitor, the trucking industry.

Analysis: In this 'Identify the Conclusion' question, we look for the logical endpoint of the argument's causal chain. The stimulus moves from automation to lower costs, and then uses the phrase 'This means that' to introduce the prediction about freight volume. The final sentence about the trucking industry serves as additional evidence to bolster that specific prediction.
