US railroad time was by individual railroads and typically very different from location to location, and railroad to railroad. This caused many collisions - and arguments over right-of-way were common (they typically ran by a timetable schedule based on time). This resulted in the railroads adopting "Standard Time" in 1883 so that all railroads could use the same time. Railroads had master clocks that received a telegraph signal to synchronize the proper time. This Standard Time that was developed is what is in use today in the US, although the methods for synchronizing clocks had much upgraded technology.
The railroads permitted the greater westward expansion not only in the construction but in the use.
For the US, it was the Civil War (1861-1865).
