                                braking simulator is available as an add-on to 
                                the gauge 1 and gauge 3 version of module D. It consists 
                                of a pair of spring-loaded brake blocks which 
                                apply pressure to the rollers in order to apply 
                                a load to the loco under test. Useful for testing 
                                the effectiveness of boiler feed pumps, blowers, 
                                and general steaming ability of locos under load. 
                                The brake may be disengaged by means of locking 
                                screws then released one wheel at a time to apply 
                                progressive braking. |
