12B, the transport knot I know of is simply an overhand slipknot. It can be used in a transport tightening system to pull the stretch out of the old Green Line as you mentioned for rope bridges or setting up haul lines or fixed rope installations. To be truthful, though, any middle-of-the-rope loop will work for that use. The benefit of using a transport knot or a Figure 8 slipknot over, say, a Butterfly or Trucker knot is the ease of removal. Non-slip knots are a real bitch to get out of the rope after you've tensioned it with a TTS.
Here are a couple good links for mountaineering knots and applications:

To add a comment about W-M's list, I'd make it the top 6 and include the clove hitch (both end-of-line and middle-of-line) , as its used extensively in lashings.
