It will have proper abutments once I've worked out where it will properly sit. The bit over the top is daft but will also have a decorative thingy in typical Isle of Stoner style. I thought about the PECO bridge but dismissed them as dull.

In other words, set the deck about 6-8mm up from the bottom of the girders.Michael Campbellhttps://www.blogger.com/profile/09740155011466713811noreply@blogger.comtag:blogger.com,1999:blog-5560322057997297901.post-66206792114243692512012-01-30T05:33:06.764-08:002012-01-30T05:33:06.764-08:00That bridge doesn't quite work for me. Maybe a...That bridge doesn't quite work for me. Maybe as an engineer I am being pedantic. However here are some suggestions that might help:<br />- The brace over the centre makes it look more like a turntable! I've never seen one on that kind of girder bridge<br />- A skew girder bridge has the girders offset longitudinally - i.e. the girders should start at the edge of the gap, even if that is not perpendicular to the track<br />- The girders should be *only just* long enough for the gap, and sit on abutments overlapping by about 12-18" (say 5mm). I suggest building out a brick/stone abutment closer to the edge of the river and then shorten the girders to suit, a couple of "bays" off either end would make it less like a turntable too.<br />- The girders are rather massive for NG. Given the above points should look OK, but have you considered the PECO NB-39 N-gauge girders? Cheap enough to try!<br /><br />As always a look at a real girder bridge will be a big help, I believe there are some NG ones in your area! There was a useful book on "Bridges for Modellers" but I'm not sure it is available now.Michael Campbellhttps://www.blogger.com/profile/09740155011466713811noreply@blogger.comtag:blogger.com,1999:blog-5560322057997297901.post-80931975467866418052012-01-30T01:50:23.508-08:002012-01-30T01:50:23.508-08:00Nice model, i like it....
