You showed new rail. Here is some very old rail. In an old industrial site next to the Erie Railroad Bergen County Line in Fair Lawn, New Jersey lies some 80-pound rail made in 1912. The yard once served a coal company among other things. The tracks are still pretty much intact, complete with switches. The 1960 Erie employee timetable still listed the main line connecting switch as active. The site is being redeveloped. I don’t know the future of these rails, but so far they have survived for 105 years.
