    A spur usually refers to a single ended track such as an industry or team  
track.  If it's connected to the same track at both ends it's called a siding, 
if it's connected to two different tracks at the ends it's probably called a 
cross over or a connector or a cut off or some similar term? 
   As for trees close enough to make a tunnel it would depend on the type and 
if the railroad thought they were not a safety hazard or not. The Santa Cruz 
branch here has some "tree tunnels" along the route, many are eucalyptus trees 
which grow very tall but have overhanging branches and drooping limbs. If your 
layout represents a specific area of the county you could look at google maps 
birds eye view and get an idea of how the trees grow there....DaveBranum
