![]() ![]() Spline sounds good as Pennsy had other stone arch bridges like this but shorter and possibly taller (Philadelphia comes to mind). Railing, it was not built with one and I would have to find out when it was installed. According to the wiki it is 43 feet from top to river bottom which is exactly what I got from myĢ) I would like 4 tracks that are replaceable.ģ) Tracks centers are the standard Pennsy practice of 13'.Ĥ) Would have to search as I have none personally.ĥ) Located in Rockville PA 5 miles north of Harrisburg and built in 1902. Rockville Bridge of the Pennsylvania Railroad-longest stone arch bridge in the world-built 1902 and still in daily use. Today, many people call Rockville Bridge the longest stone-arch bridge in the world, but thats only partly trueonly the visible outer layer of its form. This was the third bridge constructed here by the Pennsylvania Railroad. With forty-eight arches, it has a length of 3,820 feet. I would like the bridge close to as built but with the railingġ) Here are measurements taken from Surveyor Track at ground level = 106.70m river bottom 93.60m a difference The longest stone masonry arch railroad bridge in the world, one mile to the south, was built 1900-02. I'll make this as a spline since other folks might like it in shorter versions (and a few crazy ones might like it even longer, lol). What center to center track spacing do you want? How wide is it and how many tracks? Looks like 4.ģ. How far above the water are the tracks? I make it close to 100 feet.Ģ.

There is a pipeline and cabling running the length of the bridge, on both sidesĬarries 2 rail lines for Norfolk Southern Railway and Amtrak Keystone Corridor The Zinc Railing I used from Trainz, was 2 pipes 2 1/2 inch diameter, and was most probably very rusty pipes So it would have to be 3 separate versions. STONE ARCH BRIDGES: AN UNDERUTILIZED TECHNOLOGY IN THE MODERN UNITED STATES by Nicholas R. If you made it tracked, that would lock out the 4 tracked modelers who want the old time trackage. The problem with making it tracked at all, is because it had a interlocking plant right on the span, and it is downgraded to 3 tracks, now is 2 tracked, due to collapsing stonework, and it now has many steel reinforcement straps, and through bolts. ![]() I believe it was originally 4 tracked, at an 3m spacing (PRR Spacing was 13') I think it looks like 80' higher than the water (but if you made it higher, someone else could height adjust the model. Second, the bridge's 48 arches do not represent the states of the Union at the time the bridge was built the United States flag bore only 45 stars when the bridge opened to traffic in 1902.Bridge was not a simple straight span, as it had wide wye areas on both sides of the river First, the bridge is properly described as a stone and concrete bridge and is, therefore, technically not the longest stone arch bridge in the world. The author debunks two oft-told myths that have developed regarding the current bridge.

The book describes the present bridge from its 1900-1902 construction to the 1997 collapse of a portion of the downstream sidewall and the ensuring repairs. ![]() A loss of confidence in iron bridges combined with a continuing increase in the weight of railroad locomotives lead to the decision to replace that structure with the current bridge. In 1877 an iron bridge replaced the earlier structure. In addition to being a fire hazard (portions of the bridge burned in 1868), the bridge became a bottleneck as railroad traffic increased. The first Rockville Bridge was a single-track wooden Howe truss bridge that opened to traffic in 1849. In Rockville Bridge: Rails Across the Susquehanna, noted railroad historian Dan Cupper details the history of the three bridges that have borne the name "Rockville Bridge." While the book concentrates on the present bridge, the most famous and longest-standing of the three, the previous structures are described in great detail. This stone and concrete structure, the third bridge to stand at this site, has weathered ice and flood, corporate bankruptcy and merger, and changes in usage, yet it remains a monument to American railroading. More than a century after it was built by the Pennsylvania Railroad, the Rockville Bridge continues to carry mainline rail traffic over the Susquehanna River.
