Wooden deck bridge question...

[ShadowNix]

So, I built a nice wooden deck bridge with parts from Grand Central Gems.  My question is, do I lay my flex track on top of the deck, or do I take of the ties and run the rail across only fastening/gluing down?  I can't seem to find any pictures from above to help me with this.  I appreciate any help!

I used bridge track, Atlas for the straight bridge and some other companies flex bridge track for the curved. Both worked well and looked great. The curved was a lot more dificult to lay.
