dog spike railway
The dog spike railway represents a fundamental component in railroad track construction and maintenance, serving as a crucial fastening system that secures rails to wooden sleepers. This traditional fastening method consists of a large nail-like spike with a offset head, specifically designed to hook over the rail flange while penetrating deep into the wooden tie beneath. The spike's distinctive design, featuring a chisel point and twisted shank, provides exceptional grip strength and resistance to lateral forces generated by passing trains. Typically measuring between 5.5 to 6 inches in length, dog spikes are manufactured from high-grade steel to ensure durability and longevity in challenging railway environments. The installation process involves pre-boring holes in the wooden sleepers to prevent splitting, followed by mechanical or manual driving of the spikes. This system has proven particularly effective in regions where wooden sleepers remain the preferred choice, offering a cost-effective and reliable method of rail fastening. The dog spike railway system's simplicity makes it ideal for maintenance operations, as damaged or worn spikes can be easily replaced without specialized equipment or extensive track closures.
