How do you distinguish a touring bike from a speed/road bike? I would like to buy a touring bike soon, but in our country I cannot find any well known touring bike. I would like to buy a used one so I am going to visit some of the bicycles stores of our capital city. I am afraid I do not know how to recognize a touring bike.

What are the differences between a touring and a speed/road bike (e.g. eyelets on the folk)? Unfortunately I have not had enough experience to classify them based on the frame geometry but if you can tell me any tips I will thank you. :)
The distinctions are often subtle:


The touring bike will of course be slightly more heavily built (generally a steel frame).
The touring bike will have a longer wheelbase.  You will generally notice that the space between the seat tube and the rear wheel is fairly wide.  (The longer wheelbase serves 3 purposes:  More stable, smoother ride, better fender clearance, and better heel clearance for rear bags.)
The wheels will be more heavily built (at least 32 spokes and maybe even 40 on the rear), with wider rims and tires -- at least 28, maybe 35-38.
The touring bike will have eyelets on the front and rear dropouts to support racks and fenders.  (This generally means two eyelets on each side of each axle.  Plus there may be braze-ons about half way up the side of the fork for a "low rider" front rack.)  And at least 2, perhaps 3 sets of bottle bosses.
The touring bike will have a more "relaxed" geometry -- higher bar height, a little less "reach" (shorter top tube, etc), slightly more slope and "rake" to the fork.
The touring bike will have a wider gear range and a lower low gear, and usually not as high a high gear.
