These are the newest designs of O-gauge bridges from Mainline Bridges. These bridges are all designed to fit an overhead system. These designs feature a Deck Girder, Round End Through Girder, and a Straight End Through Girder.

This customer ordered 3 bridges for a project he was working on. He asked if we could paint them 3 different colors. This Deck Girder is a Hunter Green. The Small Arch bridge is a Sliver and the Curved Top Through Truss is semi-gloss black. The detail that really makes these bridges special is that all 3 of them are widened to fit a curved track. He asked that each bridge was built straight and wide so the customer could curve the track on the bridge.       About a month ago customer contacted us and asked if we could build him a 50" Round End Through Girder for his layout. We took into consideration building two separate girders and welding them together but ultimately decided to build it as one solid girder. For this span the girder plates are 3.5 inches high instead of the usual 3 inches.      CAVCLO Railroad project has lasted for almost three months. Back in May a customer contacted us and asked if we could create several curved deck girders and box piers for an Arboretum he and his son were creating. Each box pier was to have bridge shoes, riveted gussets and fully laced detail beams. The customer sent us many detailed drawings of what he wanted and measurements for every bridge and pier. It was up to us to figure out how each bridge would fasten together. The challenge of this was the size of the piers and the height of the girders. The deck girders had to be three different heights, 2.25”, 2.65” and 3.65”. We soon came to the conclusion to add a girder to one side of the box pier so the different sized deck girders would still line up and the train would run smoothly. The piers also varied in heights from 4.5” to 10.5” tall. These piers are the smallest and most detailed we have yet to build. This customer has been a pleasure to work. We now have plans in the works to continue and add bridges to his layout. To be continued…..         O-Gauge For this O-gauge project our goal was to model a bridge on the North Shore Line. The customer sent us a picture of what he wanted and a few specifics on details. The customer had decided on a riveted double track deck girder. With the deck girder he had asked that we create the two abutments in the picture to compliment the deck girder. This deck girder was the first of its kind. We designed two separate rail beds for the bridge to give the customer freedom on where he wanted to place his tracks. These rail beds fit nicely behind the girder plates so that they are not noticed from the side view. We also added rivets, lettering and custom paint to the girder rails. The next phase of this project was the abutments. We decide to create the abutments out of H.D.P.E. a plastic material. This material can be cut like wood but will last forever. We also added holes to the abutments so that the deck girder could be fasten in securely. Later when the abutments were finished we sprayed them with a textured plastic sandstone paint to create a concrete look.          |
