/**
     * Change the properties and locomotives of a consist.

     * This method takes as input the JSON representation of a consist as
     * provided by {@link #getConsist(Locale, jmri.DccLocoAddress) }.

     * locomotive that should be in the consist, if it contains the engines
     * node.</li>
     * </ul>
