Disclosed is a computer-implemented method for determining dynamic braking data for use in a braking model of at least one train, the method including: (a) determining at least one initial safety factor; (b) determining at least one dynamic braking adjustment factor based at least partially on (i) the expected dynamic braking force, and (ii) specified retarding forces of the train; and (c) determining at least one new safety factor based at least partially on the at least one initial safety factor and the at least one dynamic braking adjustment factor. Also disclosed are braking systems including dynamic braking for a train having at least one locomotive. Se describe un método implementado por computadora para determinar datos de frenado dinámico para usarse en un modelo de frenado de al menos un tren, el método incluye: (a) determinar por lo menos un factor de seguridad inicial; (b) determinar al menos un factor de ajuste de frenado dinámico con base al menos parcialmente en (i) la fuerza de frenado dinámico esperada, y (ii) fuerzas de retraso especificadas del tren; y (c) determinar por lo menos un nuevo factor de seguridad con base al menos parcialmente en el por lo menos un factor de seguridad inicial y el por lo menos un factor de ajuste de frenado dinámico. También se describen sistemas de frenado que incluyen frenado dinámico para un tren que tiene al menos una locomotora.
