Welcome to the board, sirocco123!!!
The Stout Mines can be a very confusing place. It's very easy to get lost in there. Check out Xignal's excellent maps at:

The maps should help you find your way back!
I place more flags and notes on the Stout Mine maps than any other map in the whole game because you keep moving off one small map onto another and it was difficult to keep track of where you were and which direction you needed to go. You might try doing that when you get to the East side tracks!
Hope you find your way!! Keep us posted!!!
