The Ross bridge is basically their turntable structure, including walkways and safety railing, but without the house and house platform, to be used as a stationary girder bridge.
It does not come with any abutments, so you can mount it at any level you want and build your scenery up to it.
The shape of the girders at the ends would not make it suitable for use as an elevated railroad structure as in your photo. One of the other commercial products designed specifically for an el structure, such as the system by Bridgeboss, would be better IMO.
