    Made up the plate girder sides from bits of card, styrene and cereal packet..............

    ... and for anyone looking to count the rivets, don't bother there ain't none :avatar:

    Progressing nicely Ed. coming on a treat.whats next .... Track and ballast. Did you decide on how you are going to feed the track itch power?

    Cheers

    That looks really good Ed, what are you doing about track connections? :)

    Haven't quite made me mind up about power yet.

    Just been trying it out in the garage and I may have shot meself in the foot.

    Didn't take into account the width of the plate girder sides.

    It was 51mm between track centres but the plate girders now make them closer, maybe too close :whatever:

    :scratchchin:

    Hard to say Ed. do you have a track gauge you could try out ?

    Better finding out now mate.

    G`day Ed,

    That bridge is looking great and the girders are a very nice scratch build.

    You can go considerably closer on your track spacing than 50mm as long as it comes back out again before you hit a curve. My traverser is 40 something mm`s ( I`d have to measure it again..????) but it works.

    Normally you would need 100mm between the girders......25mm from girder to track center, 50mm to next track center and finally another 25mm to the other girder.........but?????? you may be able to reduce the clearance between the tracks and the girders down closer to 20mm and possibly the clearance between the tracks themselves maybe down to 47mm.?????

    That would gain you maybe 13mm so we`re down to 87mm between the girders.

    You would have to do some testing with 60 foot coaches, especially at the ends of the bridge if there is a curve commencing straight away.

    Otherwise you may have to lift the girders and move them out I would think.????

    Hope this helps

    Looking good Ed. :thumbs:

    As for track spacing, I have the tracks at 43mm centres on the sector plate of Jay Dubyew Nth Yard. Yes, I'm running HO rolling stock, but the US stock is approximately the same width, some is actually wider than British OO !

    Thanks Gary, but I think I need to allow a bit of 'wobble' room or trains passing at speed could side swipe each other.

    I've taken the plate sides off for now and am thinking about some sort of fencing instead.

    I feel I need to put something along the bridge approaches, to avoid anything doing a nose dive onto the garage floor :eek:

    Currently thinking about using some bits of rail as posts glued into holes along the approaches, with wire soldered between them to look a bit like key clamp handrails. :scratchchin:

    I've been thinking along the same lines Gary, basically extending the timber base out with card to sit the plate sides further out.

    However as the ends of the board are angled, moving the plate sides I made too far out make them too short.

    But after staring out your drawing for I don't know how log, I suddenly thought about moving the plate sides just enough to give more clearance by sitting them partly on a shelf attached to the timber base, and partly still on the timber base.

    [​IMG]

    Lump of BluTack to test it.

    Couple of lengths of old track placed in roughly the right place.

    [​IMG]

    There is a red line (honest) indicating the overhang.

    Since the plate sides haven't moved very much (about 8mm), they're not too much shorter at the edge.

    Might get away with this :whatever:

    G`day Ed,

    You could always glue one or two strips of card under those girders and over the top of the brick edges you already have there. That would pack it out a bit and also better support the girders.

    Card might do it Gormo but I've just found some 6mm square styrene tube, which might well do the job.

    Watch this space, as they say :avatar:

    New 'Girders' attached to the stonework and the plate girder sides moved out, giving more clearance for the track.

    [​IMG]

    But.... although the longer sides are a little short (not really noticeable), the shorter sides are a little too long due to the edge being an angle.

    [​IMG]

    Not a major problem, just requires a bit of cutting.

    I added the legs so that it can be stored on the work desk when not in place, instead of siting on it's edge on the garage floor leaning against the layout.

    Certainly looks like a robust enough build Ed. job done. Now for the track.:thumbs:

    That's better.

    [​IMG]

    I need to do some more plate girder sides to finish the approach in the foreground, but I want to get all the track in place and get some trains running.

    Decided to just use a pluggable terminal strip for power to the bridge for now.

    I looked at jack plugs but most seem to be rated at 1 amp, which could be a bit low if two trains with lights etc were crossing at the same time, albeit for a very brief period.
