Caltrain has 93 Nippon Sharyo bi-level Gallery-type cars and 41 Bombardier BiLevel Coaches in revenue service as of 2017. Revenue train consists are made of single type of cars; the Bombardier cars are never mixed with the Nippon-Sharyo gallery cars. Of the Gallery cars, 66 are coaches and 27 are bike-accessible cab cars. Caltrans purchased the first 63 gallery cars in 1985 when it began subsidizing the commuter rail service. The other 30 were purchased by Caltrain in 2000, and the older cars were rebuilt by Nippon Sharyo around the same time. Each gallery car has one set of exit doors on each side of the car.
