The short answer is that nobody really knows. The Central Pacific Railroad had a maximum of about 12,000 workers at one time, and the Union Pacific probably had a similar number, but people came and went, so the actual number who ever worked is significantly larger, but unknown.

Both sets of tracks were built primarily by immigrant laborers, with the Central Pacific employing mostly Chinese workers and the Union Pacific workforce made up of mostly Irish workers.
