I am Renovating my kitchen and am removing the wall between the kitchen and dining room.

The roof is constructed with W trusses that span the entire house. The wall rests beneath the middle of the trusses, but only halfway along from an exterior wall. After searching on-line for a while I have found several contradictory answers.

Any insight is welcome.

If those pictures were all taken from the same vantage point, your wall is parallel with the trusses & rafters, so you shouldn't need to worry about any load on it. Also, once you've taken the wallboard off, you can see there are no headers over the door or pass-through opening. Going strictly by what is shown in these pics, you should be OK, but without being there to see in person there's always the chance that somethingis bearing on it.

The photos are not taken from the same vantage point and the wall runs perpendicular to the trusses. Also the main support beam of the floor runs directly under the wall in the same direction as the wall

Even though the truss runs different from what BigRed thought he is still correct. Lack of headers for the pass through and door indicate they carry no load. By the way that wall is put together I don't believe it is original, or you have some heavy drinking carpenters in your neck of the woods. The pass through framing is a joke. It does even have a 2x4 all the way along it and the door looks to be a single 2x4. Rip it out.
