Railroad Turnouts

NARSTCO is proudly North America's leading railroad turnouts supplier of steel railroad ties and turnouts. We hold the No.1 market share of steel railroad tie products supply in North America. NARSTCO has earned this position through a dedication to provide our customers with superior products, in field service, excellence in engineering and a commitment to service. We are the technology leader in the steel railway tie product industry.

NARSTCO steel railroad track and turnout tie sets provide a solution to the problems railways are facing in the 21st century. Steel railroad ties and turnouts in railway track extend other track component life and operate with optimal efficiency under the most adverse conditions. NARSTCO steel railroad track and turnout ties are installed with less cost, labor and material; and most importantly are proven effective.

A railroad switch, railroad turnout or set of points is a mechanical installation enabling railway trains to be guided from one track to another, such as at a railway junction or where a spur or siding branches off.

A railroad turnout is an arrangement of a switch, a frog and closure rails, which diverts rolling stock from one track to another. Because industrial trackwork often handles lighter loads at slower speeds than mainline railroads, industrial turnouts are constructed with lighter materials and components.

We manufacture steel railroad ties and turnout sets for ethanol plants, grainery, industrial facilities and petro chemical transportation companies. Our product solutions include rail switch and extension track with engineering support for rail design. Mainline railroads and industrial turnouts are installed with less cost using steel railroad ties, plates, joints, spikes and spurs. Steel ties on ballast deck bridges offer reduced load and thickness for future resurfacing or rail replacement. Narstco supplies track ties ranging from load out terminals and loading platforms to line haul operations and railway loop structures.

The railroad switch consists of the pair of linked tapering rails, known as points (switch rails or point blades), lying between the diverging outer rails (the stock rails). These points can be moved laterally into one of two positions to direct a train coming from the narrow end toward the straight path or the diverging path. A train moving from the narrow end toward the point blades (i.e. it may go either left or right) is said to be executing a facing-point movement.

Unless the railroad switch is locked, a train coming from either of the converging directs will pass through the points onto the narrow end, regardless of the position of the points, as the vehicle's wheels will force the points to move. Passage through a switch in this direction is known as a trailing-point movement.

A railroad switch generally has a straight "through" track (such as the main-line) and a diverging route. The handedness of the installation is described by the side that the diverging track leaves. Right-hand switches have a diverging path to the right of the straight track, when coming from the narrow end and a left-handed switch has the diverging track leaving to the opposite side.

A straight track is not always present; for example, both tracks may curve, one to the left and one to the right (such as for a wye switch) or both tracks may curve, with differing radii, in the same direction.
