    Does anyone know of any good texts or websites that explain the principles of bogie design and equalisation beams in particular. This would apply in general to locomotives or any other rolling stock.My limited and probably incorrect understanding is that an equalisation beam can effect the springing of an adjacent axle when an axle moves up or down due to a track undulation. But to what advantage over individualy sprung axles I am not sure.There were some interesting articles in railway magazine in recent years about continental bogies and such like but, I still couldn't grasp the basics.
    Thanks in anticipation etc.

    Would this also include "Relieving Bogies" as fitted on some Brakedown cranes?
    These were fitted to the small bogie wagons either end of the crane which could be lifted off the track when required.
    The relieving element was to reduce the axle load on the main undercarriage of the crane itself during transit.

    I believe some specialist wagons such as those designed for carriage of heavy transformers were also fitted with Equalisation beams of some form. These would be dating back to early 1920s or so.
