context_page_description: A concrete sleeper or concrete tie is a type of railway sleeper or railroad tie made out of steel reinforced concrete.
  Concrete sleepers are less elastic, and consequently noisier than wooden sleepers as trains pass over them.
context_section_description: Advantages include: They do not rot like timber sleepers, are fire proof, their extra weight makes track more stable (particularly with changes in temperature), they can withstand fire hazards better than wooden sleepers, they give more retentivity to the track, they have a longer life than wooden sleepers, and they need less maintenance, resulting in lower ongoing costs and fewer track closures. Additionally, concrete sleepers are not soaked in creosote like most wooden sleepers (used mainly in Europe), therefore they are environmentally friendlier.
