CS&I #48 was part of an order for 5 convertible streetcars from the Brill company in 1901.
The cars were rebuilt in 1908-1909 to better survive the Colorado Springs climate. All of the cars remained with the company until it shut down in 1932. Number 48 was sold and turned into a house for the next 70 years before being purchased by the museum and moved to the car house.
Car 48 is one of two surviving CS&I cars, both at the museum and the only surviving Brill convertible.
