Again I dont know where to look. (usally I am the one asked where things are LOL) I am looking to find tunnels graphics. I want to see if it is possible to change the default graphic of thetunnel in the game with another type.  is there such a thing>

I think GoaSkin experimented with different tunnel entrances a few months ago, but there were some roadblocks he encountered. I'm not sure anymore if he released some beta files, but you might find his thread at ST.

it sure is possible to change the tunnels

On the STEX, fukuda released a thing that changed the look of the rail tunnels
