In the thread, Holohan contends that the standard railroad gauge in the U.S.—4 feet, 8.5 inches—derives from the way that rail lines were built in England, where engineers based the width of their railroads on the spacing of road ruts in Imperial Rome, which were in turn designed to accommodate the size of horses’ rear …
What materials are needed to build a railroad?
Ordinary materials include railway sleepers, steel rail, rail fasteners and some construction equipment. Preparation works primarily refer to check the complement and integrity of all materials.
What type of steel is used in railway tracks?
The rails in use are made of steel containing 0.7 per cent carbon (C) and 1 per cent manganese (Mn) and are called C-Mn rail steel. It is a wear-resisting grade steel and is commonly referred to as Grade 880 rail, or 90 UTS rail, corresponding to a tensile strength of 880 mega pascal (MPa), or 90 kg/mm {+2}.
How wide can a train be?
The maximum width for unrestricted movement in the US, Canada, and Mexico is 10 feet, 6 inches. Loads less than 11 feet wide can generally move without restriction as to train handling.
How are railroads constructed?
A railroad track is made up of two parallel steel rails set a fixed distance apart, called the gauge. The rails are connected by railroad ties, usually bolted to them. The ties are set into the loose gravel or ballast, which typically consists of loose stones to help transfer the load to the underlying foundation.
What is the average life span of a railroad rail?
With a rail life of 1,000 MGT, that would be 2,000 days, which is about 5.5 years; at 2,000 MGT rail life, 11 years. So your 10-year estimate is pretty close as a ‘rule of thumb’ or ‘seat-of-the-pants’ method. – Paul North. “This Fascinating Railroad Business” (title of 1943 book by Robert Selph Henry of the AAR)

What is the standard rail length before continuous welded rail?
That decade saw the first use of continuous welded rail (CWR), also known as ribbon rail, which is laid in lengths of 1,500 feet or so (roughly a 1/4-mile), rather than 39-foot track bolted together. Aside from saving railroads millions in maintenance costs and derailments CWR does not buckle, because it resists thermal expansion and contraction.
