P: What are treated railroad ties? Benefits of Treated Railroad Ties Despite the use of other types of materials for railroad crossties, wood remains the prevailing choice.
And with good reason. Even when wood crossties are treated, they can have great environmental benefits, too. Of course, a tree is the source of the wood manufactured to make a crosstie. During this time of growth, the tree is absorbing greenhouse gasses. Brief History of the Treatment of Crossties The process of treating crossties with pressure dates back to the mids.
Most of the woods used today for wooden crossties are hardwoods. Preservatives Used to Pressure-Treat Crossties The majority of crossties treated within the United States are preserved with creosote, but other preservatives are used, such as copper naphthenate, or ACZA.
Railroad ties are, in a word, iconic. They have a uniquely American ruggedness, conjuring up visions of freight trains barreling across the landscape. Railroad ties are sturdy, nearly impervious to rot and insects, and rarely need to be replaced. Railroad ties are made from all different types of wood, including oak and various other hardwoods, to handle the pressure of ton rail cars riding over them daily.

They do, however, come with some drawbacks that preclude them from being the right choice for every project. Railroad ties are treated with creosote oil — a strong preservative made from coal and wood tar — that can make them poisonous to vegetables and a poor choice for projects where bare feet or hands might come into contact with them.
