    Everywhere I've gone there's railroad bridges with double rails, like this one http://bridgehunter.com/photos/13/63/136324-L.jpg
    So I was wondering exactly why double railroad tracks are needed on bridges

    I think you also see these double tracks on very sharp turns..

    Stormwolf. Listen Cobber, I'm not picking you out for special posts, it's just that you are Threading in areas where I have some expertise. ( HE HE HE ). Yes, believe it or not, I was once a great railwayman/boy. The love of the Rail never leaves you. Especially if you are a Steam Rail man. To have a go at your question; could it be for extra ballast, the tram line being without normal embankment stability? My friend, John Galt, may like to have a go at this. westwind.

    Woah you replied to every single one of my threads man.. O_O
    Well I've heard people say things like how it stabilizes the train.. But Im just wondering why only on bridges?

    normal embankment stability
    I have no idea what that means at all...

    I did some extra research and wrote an article about it on my blog!

    Can you check it for accuracy and see if theres any mistakes?

    I assume you're referring to the Ayn Rand novel? Did you know part two of the movie is scheduled to come out in October?

    A little off-topic, I know but I couldn't help myself.

    I'm going to take a wild guess. They are for two separate sets of tracks to cross the same bridge, so you wouldn't have to make the bridge wide enough to accommodate two trains at once. Let the trains pass one another somewhere else.

    Edit: Have a look here.

    I actually doubt that, it's highly unlikely to risk accidents just to save space on a bridge :O
