I took a better picture of the October 1887 rail:

As long as the FRA or any of the Rail Defect companys like Sperry Rail, Herzog, or HTT don't find anything wrong with the steel then its ok to use. Privateley owned sideings are not subject to Rail inspection to my knowlage by the FRA.
in regards to older rail such as the examples that the other posts depict, does the FRA or state DOT's have any guidelines or concerns about the age of rails becoming a safety issue???

They "sorta" get service. Three hopper cars have been sitting on the east side of the road, where the sidings used to cross the road. VTR replaced a few ties to get them there.

There is quite a lot of 1920s stuff still out there, not uncommon at all. The 100 ARA-A section photographed above is one of the more common surviving sections. I've also seen a lot of 130 PS ("Pennsylvania Section", the railroad, not the state) from the teens and the 1920s, still in track. In fact, the former PRR Bald Eagle Branch in PA was entirely laid with this rail unti l they replaced it all a decade or so ago, with 132 # CWR.
Rail from before 1910 is quite rare, and Class Is generally will not re-use rail from before about 1935, since it is not "control cooled" (a process that greatly reduces the incidence of rail flaws). But there are many short lines out there with rail from the early part of the 20th Century. Generally, only the heavier sections have survived, since anything less than 85 # per yard simply will not support modern freight cars. Those legendary short lines with 60- or 70-lb. rail are almost entirely gone.
The oldest rail I have ever seen in track was on the Winchester & Western in Bridgeton, NJ. It was an 1887 section of 89.5 # rail (a section I had never heard of), rolled by a mill I had never heard of. And they were running 100-ton cars over it! I was with a group of Swedish track engineers, and they were amazed.
I got my early education in rail sections at Conrail in the 1970s. With all the predecessor railroads, and all the deferred maintenance, Conrail had literally dozens of different sections, each requiring its own joint bars and tie plates. Some of it, like the NYC 105 # "Dudley" section, was very good rail, but because of its odd dimensions, had to use secondhand bars and plates, which meant yard or branch line use only.
Rail life is directly related to the traffic moving over it, and is generally expressed in cumulative millions of gross tons (MGT). On average, rail in North America averages 700 MGT before it is replaced. Of course, curve rail wears out faster, but on low-tonnage tangent track, life is essentially infinite. On a one-MGT (annual) rail line, presumably the rail would last 700 years!
