Don't quote me on this, I may be wrong. Sperry made gyroscopes back before they had GPS. I am guessing that a "Sperry" car was used for track maintenance. Using the gyroscope, the car could tell if the grade was bad. Sorry, best I could do off the top of my head,

It's an automated way to test/inspect the tracks. It's a self powered railroad car that uses an electrical current to look for breaks in the steel.

It is a piece of equipment that checks the condition of the rail head, web and base. Also called a "track geometry car".
Sperry does manufacture other on track equipment, primarily rail grinders.

I will take a wild guess: it is the car that carried the work crews.
