Big Ten Curve Railfan Cam

The Famous Big Ten Curve

This PTZ railfan camera overlooks the celebrated Big Ten Curve near Arvada, a renowned stretch of mainline track that climbs the foothills in a dramatic succession of broad loops. Freight trains thread the winding grade as the rails double back on themselves to ease the steep ascent into the mountains.

A Front Range Panorama

From its elevated hillside perch, the lens sweeps across the open grasslands and undulating ridges of Colorado's Front Range. The expansive foreground of tawny meadow and scattered pines gives way to the Denver skyline shimmering far across the plain.

A Magnet for Railfans

The iconic geometry of the curve has made this one of the most cherished trackside vantages in the region. The pan-tilt-zoom view follows passing trains along the sinuous route, offering an immersive real-time window onto the railroad and the surrounding terrain.
