In this video, I will show you how to drive the double decker AC Caltrain from San Francisco to San Jose in Train Sim World 4. This is a realistic and immersive simulation of the Peninsula Corridor, a commuter rail line that operates on the west coast of the United States. You will see the stunning scenery of the Bay Area, the iconic landmarks of San Francisco, and the busy stations along the route. You will also learn how to operate the MP36PH-3C CTX locomotive, a modern and efficient diesel engine that has been serving Caltrain since 2003. I will explain the features and functions of the cab, the controls and indicators, and the safety systems. You will also get to experience the Bombardier Bi-Level Cab Car, a spacious and comfortable passenger car that allows you to drive the train from the opposite end. This video is suitable for beginners and experts alike, as I will provide tips and tricks on how to master the Caltrain service.
