Answer

Answer:

They could transport many materials or goods at once.

Brief Explanations:

Steam - locomotives had large - capacity for cargo, allowing more materials or goods to be transported per trip, thus reducing the per - unit transportation cost. Other options are incorrect: running on steam isn't free, they were complex and costly to build, and safety wasn't the main cost - reducing factor here.
