This was the movement that advocated state control of railroads and currency expansion?

Populist.

Explanation:

Populism is a set of political positions whose main objective is to work for "the people" and against the "elite". This position advocates that the "people" are good and any political decision must be made in their favor. Usually "the people" are defined as workers, ethnic minorities, or the lowest social class.

For this reason, those who advocate this political position in their speeches promote that the less favored obtain greater benefits. Although in practice this is not always that way.
