RMweb Gold Harlequin Posted February 4, 2019 RMweb Gold Share Posted February 4, 2019 Hi Bob, While RMWeb was down I came across this video where the modeller creates a slightly different form of bridge but the techniques may still be informative. 2 1 Link to post Share on other sites More sharing options...

Great find, Luke Towan is a modelling genius! His videos are very well presented. I'm sure all of us can take something away from them. 2 1 Link to post Share on other sites More sharing options...
calvin Streeting Posted February 4, 2019 Share Posted February 4, 2019 ok just read back (your not a novice ) like the sweeping trackwork etc.. and i see embosed plastikard would be way to go as it would match more of the existing structures you have aka kits etc) and on that i see you built a simple will's kit shed, which is much the same as working in plastikard, only thing diferent is you need to make the desgin and make the bits of the kit I can also see you moked up where bridge is going (about half way between both ends, if i am right ) i could photo step by step when i make next building, but i am sure we can hlep with working out a simpleish brigde. and building your own structures is fun and very satifying as you get what you want, not what the kit will make 1 1 Link to post Share on other sites More sharing options...

Bob Hello Bob As Calvin said above the best way is to draw it out then make a mock up from cardboard, cereal boxes etc. Plastikard is quite easy and forgiving to work with. The bridge being on a curved line might make it slightly more complex, but as it's a girder bridge you haven't got a curved roof to worry about. I presume the inside would be brick lined, it should be easy to match some embossed plastikard to the skytrek front. Charlie 1 1 Link to post Share on other sites More sharing options...

Charlie Hi......Thanks for the kind posting.....I am at the moment minded to use the Skytrek facades for ease of build and my current skill levels...in the image I have stood two Skytrx brick retaining wall sections into position to form the inside wall.....just a thought,,,....

(It was very difficult to spot on the image...I should have mentioned their use).........I wondered whether these would be okay...as they seem a reasonable possibility to form the central section,,,,,, the clearance height seems okay too.....may lash up something with these and see where I go...?

calvin Streeting Posted February 4, 2019 Share Posted February 4, 2019 oooh thats nice i take it you have enough for both sides ? and thus its more about the supporting back structure and road bed and underside detail ? 1 1 Link to post Share on other sites More sharing options...

Hi..... Yep I've enough to complete both sides, plus a bit more as I did previously purchase Skytrek retaining walls and piers / caps (which are the same as here) ....,,,thought of using the walls for the central section to)....so should be able to make up a decent length of bridge.... and perhaps a small retaining wall with grass etc on the one side,,,,,if you catch my drift...? Any information on the construction of the road section / underneath...ie girder look ....would be good Regards always.....

BobM Posted February 4, 2019 Author Share Posted February 4, 2019 Using the video info you provided...thought of giving the impression (with a gap) that the road was on shock absorbers even though it is a road bridge....? Bob Link to post Share on other sites More sharing options...
calvin Streeting Posted February 4, 2019 Share Posted February 4, 2019 yep i get what you meen. so two largeish wooden blocks, with a thin 3mm ply road bed going over top. (it might be good to put a small inlcine on boad edge so the bridge is the apex of the hill as it hits back wall, makes backdrops easyer and adds alittle extra 3d look few roads are level. then this should make gluing sides on etc, and sturdy. the ply road bed would probably be level with top of steel girder, and then we need to look at pad stones, and expansion plates etc and how the underside, and ends would look etc. most are beam and blocks or brick infill which can be made with strips of styrene etc. a good point of ref on the subject of underside is https://www.newrailwaymodellers.co.uk/Forums/viewtopic.php?t=16973&start=150 any help ? 3 1 Link to post Share on other sites More sharing options...
BobM Posted February 4, 2019 Author Share Posted February 4, 2019 Cheers my friend..... Great inspiration here......there are a number of bridges close (500 yds) by at home on the old Wombourne / Oxley Branch...now a delightful walk...will go on my next day off and take some images for reference....
