I often see a second set of rails in between the regular rails that trains roll on. They may go a few hundred feet and then merge together. What are these for?

Well, I tried to post a link twice, both times, worked fine by itself, but when I clicked on it in my reply, it took me to handrails on stairs. If you search railroad guard rails on track, you should get a link that is not about stairwells.
This keeps taking me to stairwells, maybe it will work for you, or copy and paste it on the address bar and try it:

AHA! It has something to do with the (rail_transport) part of the link not working in this reply, but works fine if you copy and paste the whole thing in the address bar.
try this one RR guard rails
No answer yet, still looking for a working link.
Gary,
Go to Scotie's link above. When you get there click on Guard Rail rail transport.
