    Tomorrow I’m starting my tinkering on building myself a rail-bike. A rail-bike is a bicycle that has been modified to be able to ride on the rails of a railroad. The front wheel has a device attached to it so that the bike won’t steer off the rail while an outrigger is used to support the bike using the other rail.
    (Do an image search if you can’t picture this.)
    Anyways, anyone have experience with this or have any advice other than the obvious things like “don’t get hit by a train” or get caught trespassing and such?

    I guess i just don't understand why?

    I'm too afraid to go near railroads, i had a friend who got hit by a train, deathly afraid ever since.

    i get it: railroads go places cars don't, and they have easy grades. but where are you thinking of riding it? haven't they torn out most of the unused rails in your area?

    Can you all really not seen the fun in this? I don't know your area but Atlanta has a fair amount of abandoned track that goes through some pretty interesting areas. I wouldn't worry much about trains, you can hear them a mile before you seen them and I would imagine the vibration on the track would be fairly apparent.

    There is virtually unused track from my town to the next and beyond for about another 7 miles or so where it ends for a total of about 12 miles one way. Since there is little chance that it will be converted into a multiuse trail, I figured I’d do the next best thing while satisfying my need to tinker.

    Well, I’ve got it all just about done, though I won’t know if my design will actually work till I try it. My biggest problem so far was that I must easily cross road crossings and travel through switches. This limits me to using only the top and inside one inch of each rail like the trains do, but I think I have figured out how to do this.

    I’ll try and post some pictures when I’m done.

    go balls out! a handcar style platform with a mounted wheel-less frame mounted for the drive sytem. You could go with some fixed length axels and polyurethne coated "dolly wheels" as the actual contact wheels.
    This could start a whole new industry, built the first one macGyver style, and always with a new improved protype in the wings, evolving into oversize aluminum, titanium and carbon fiber models, make sure all upgrades are incompatible with older models necessitating the purchase of an entire new system.
    WAIT!, this has already be done with road AND mountain bikes, nevermind.

    Looks like fun to build, but completely impractical in my area. Donkey Kong could have really used one of these.

    A few more tweaks and I think it'll work...

    Ive been looking at plans for one of these off an on for a bit on the interwebs .. there arent many unused rails around my parts . so my main concern would it would have to be light enough for a quick dismount to get out of the way of the train.

    Well, I’ll have you all know that I’m rather pleased with my first try at this. I figured I went about five miles out and back with only one major crash (had to look for my wallet and everything) with less than ten lesser derailments, but I think this was largely caused by the unmaintained rail line. Things such as uneven track, dirt and vegetation along the inside edges of the rails combined with friction and the occasional binding due to my design were all contributing factors. Certainly with enough time and money to through at it I’m sure this would work really well.

    All in all I think it works surprisingly well. See pics here: http://velospace.org/node/42235

    Are rails open to everyone?

    Seems like fun as long as I don't get a citation.

    I don’t have permission; therefore it is likely viewed as trespassing.

    Well I wish you luck then.

    The city I live in is crisscrossed by rail road tracks.

    Might be something worth looking into.

    Thats cool, so it's a completely non destructive mod?

    If nondestructive mod means that I can simply unbolt the stem clamp and remove the attachments at the quick releases and use the bike as it was before, then yes.

    The Panasonic frame is dead.
    Derailed today and the rail guide out front caught a rail tie solidly resulting in an instant stop at around 16 MPH. Result? Me over the bars but OK. Bike? Bent frame at the top tube behind the steer tube and in front of the seat tube, down tube bent at the steer tube and in front of the bottom bracket. The front tire now rests beside the water bottle. There doesn’t seem to be any other damage though.

    Stay tuned for #2…


    PS. I guess it was a destructive mod after all…

    Any after the crash pics?

    Also, maybe have the guides fully straddle the rails? would prevent derailment no?

    TL;DR, just speed-read. This actually seems so fucking awesome compared to what I had initially thought.

    dayum! that really makes 16mph seem a lot faster. Btw, how do you carry that thing to the tracks if those balance arms dont fold?

    Just a demonstration of the working technique for including a photo in a forum post. It's not as if this question doesn't come up every six weeks or so. Moving on...

    wow, glad you're okay.

    i had been thinking that just having the two rail guides, one opposite the other, would be highly susceptible to derailment. although i don't know off the top of my head how you would do it, it seems like having two sets of guides arranged in a rectangle, like a typical truck (to use the railroading term) would be a lot more stable. there is also the fundamental weight balance problem with having the bike on one rail. you need to find some way so increase the normal force on that opposite side. although the four wheel design would help the most, in my opinion.

    Just remove the pins and slide the pipes out of one another, then I toss the bike and attachments in the car.

    Yea, it's a work in progress as this was only my first prototype and I'm hopefully learning from my mistakes as I go. I've got some ideas to try in hopes of avoiding such drastic results should a derailment occur. Stay tuned…

    I would like to see them.

    As I've said my town is covered with tracks so I think it would be good to base my design off of someone who has built it.
