The crosstie spacing of mainline railroad is approximately 19 to 19.5 inches (48 to 50 cm) for wood ties or 24 inches (61 cm) for concrete ties. The number of ties is 3,250 wooden crossties per mile (2,019 ties/km, or 40 ties per 65 feet) for wood ties or 2,640 ties per mile for concrete ties.
Rails are frequently measured in weight per yard, such as 135 pounds (61 kg) per yard (0.91 m). Through the mid to late 20th century, rails were typically bolted together, this has given way to continuously welded rails that have fewer joints. [5] Rails are secured to the ties using a fastener. With wood ties, spikes are commonly used.
Many railways use large wood screws, also called lag screws, to fasten the tie plates (or baseplates) to the railroad ties. Tie plates came into use around the year 1900, before which time flanged T rail was spiked directly to the ties.
Rails were typically specified by units of weight per linear length and these also increased. Railway sleepers were traditionally made of Creosote-treated hardwoods and this continued through to modern times. Continuous welded rail was introduced into Britain in the mid 1960s and this was followed by the introduction of concrete sleepers.
