This book covers the theoretical and practical design of prototype bridges, and how we can model those.
Title / Description
Purpose of Bridges and Trestles
Bridges allow for openings, conserve ground space, to span gaps, to handle locomotives and cars (turntables and transfer tables), to connect to car floats, to save expense, and to serve our modeling needs.
Elementary Bridge Engineering
The chapter covers basic terms, stresses in trusses, indeterminate and determinate stresses, Cooper's Loading, Highway loading, and lateral and sway bracing.
Types of Bridges
Bridges, trestles, viaducts, culverts, deck or through bridges, steel, timber, and masonry construction materials, movable or fixed, riveted, welded, or pin connected, simple, cantilever, continuous, arch, or suspension, beam, plate girder, or truss, and types of trusses.
Selection of Bridge Type
Selection of the type of bridge to use depends on the span and apparent age, terrain, waterways, traffic.
This chapters covers pipe culverts, box culverts, arch culverts, modeling box and arch culverts, culvert substitute, station passageways (passengers move under track), and layout applications of culverts.
Abutments, Piers, Shoes, and Pedestals
This chapter covers abutments and how to model them, various piers and how to model them, pedestals and shoes and how to model them.
Covered in this chapter about bridge floors are railroad bridge floors, and highway bridge floors. It also covers how to model them as well as how to deal wiring track on bridges.
This chapter covers timber and concrete bream bridges and how to model them.
This chapters dives into the details of how a plate girder bridge is constructed and how we can model them. It covers the plate girder, the deck plate-girder bridge type, the through plate-girder bridge, how to deal with bridges on curves, and how to add the rivet detail.
Steel Truss Bridges
This chapter covers early metal truss types, steel truss types, truss-bridge members, assembly of a truss, reading truss plans, low truss bridges, and through truss bridges.
This chapters describes timber arch bridges, timber trusses, and how to model timber bridges.
In addition to the nomenclature used for arched bridges, this chapter also covers the type of shape of an arch, arch hinges, stone arch bridges, concrete arch bridges, and steel arch bridges. All are described to they can be modeled.
This chapters covers swing bridges (including turntables), bascule bridges, vertical lift bridges, rolling bridges, floating bridges, transporter bridges and cableways, and transfer bridges.
Discussed in this chapter are cantilever, continuous, and suspension bridges.
This chapter covers timber, steel, and concrete trestle bridges. It includes how to make a jig to create scale bents and how to assemble the trestle bridge.
This chapter includes refuges (for fire barrels), using bridges to mask mirrors on the layout, telltales, signs, draw bridge protection, auxiliary crossings, switches on bridges, navigation lights on draw bridges, bridge color, and how NOT to model a bridge.
