They were a useful design and because of their light weight and short wheelbase, were often used on dockside branches with sharp curvatures, including that at Weymouth, Dorset.
In 1949 five were put to work on the Edinburgh-Dundee-Aberdeen route and proved the ideal engines for its stiff gradients and sharp curvature.
As with spirals, the main limitation in laying out a horseshoe is keeping the radii of curvature at or above a desirable minimum, as sharp curvatures will limit the speeds at which trains can run on the line.
The sharp curvature slowed train operation and generated a loud metallic scraping noise.
German scientists have made tiny nozzles that bend gas molecules through a sharp curvature.
It is thought that this tear is caused by the unusually sharp curvature of this part of the arc coupled with the interaction of Bowers Ridge in the over-riding plate with the subduction zone.
Out here the planet's sharp curvature had no effect on one's perspective, the curve was for once invisible, the cliffs free and clear even thirty kilometers away.
The top structure uses a mesa to avoid a sharp curvature of the p-region next to the adjoining n-layer.
In both cases, this wheel arrangement was used to provide a lower axle-load due to track conditions as well, particularly in the case of the DJs, a shorter wheelbase more suited to sharp curvature on secondary or tertiary routes.
