    I was wondering how grade crossing signals were activated. Is it a block control thing or are switches placed on the rails? Thanks

    The most basic systems use the train to complete a circuit across the rails which in turn triggers the lights and gates. A more advanced system is also available that takes in account train speed to better time the lowering of the gates.

    Is there a website on the net somewhere that tells you how most railway equipment works?

    I was going to post some information here, but I'm not exactly sure what you're looking for. I did a Google search for grade crossing signals and found several sources of information.

    Some grade crossings with gates will also tell the Signal Maintainer the speed of the train across the crossing as well.
