Hi,
The use of the Scenery move button was lost when TS2009 came along, and I have spent the years after that with every update to Trainz hoping the 
Powers 
To 
Be (PTB) to have make it available again as a way to move the camera.
Alas, whatever was "broken" before TS2009 which allowed this trick, has been fixed for good and seems to never ever come back as a built in tool for the tracking camera. :'(
I so wish PTB would allow a better tool, or remove that large bounding box stopping the tracking camera from reaching the ground in hill country. I been nagging about this ever since I saw it in TS2009 and on the TrainzDev Forum when we had that, but it seems I was the only one bugged by it so nobody cared it seemed.
I'm glad to see others share the frustration with placing tracking cameras, I hate the up in the air look, I want to be near the ground, at eye level, and I loved the old trick and miss it greatly and share the wish I see others now have to have some sort of that kind of tool back - please?
My work around is similar to clam1952, except I save a copy of my map, level the ground in about a 500 meter radius at the area I want the camera, about 1 meter lower then I need, then put in the cameras I need, save and exit out of Trainz.
Then I open for Edit in Explorer my map and the copy of the map, put the *.obj in my map in a safe place and copy over the *obj from my copy, commit the maps and enter my main map again to check if the camera did end up in the place I needed.
If I somehow messed it up - it happens as it is so cumbersome to keep track of the ground where it was when I have leveled it, I start all over again... 
 
I miss the old trick with the Scenery button, so much faster, easier, better, please PTB, can we get it back, please!! :udrool:
