This work outlines the role of system simulation for the development process of railway brakes. The principles of systems engineering motivate the use of computer based simulation in order to enhance the understanding of systems and to verify the behavior of systems in early design phases. For this reason, the Modelica library "Virtual Train Brakes" is presented which enables engineers to generate simulation models of railway brakes and to perform system simulations during different phases of the development process. By modeling and simulating the brake systems of a passenger and a freight train, the capability of the library is demonstrated and further investigations are motivated.
