What device, naturally found on steam locomotives, was utilized to create the necessary vacuum for early brake systems?
Answer
Ejectors.
Steam locomotives were naturally equipped with ejectors, which are Venturi devices that use steam to create a vacuum. This made them mechanically simpler than the compressors required for competing air brake systems.
