Gerry, the drawing is the same. In the shop pics I'm just looking at it from the wall side. All the piping will be running away from the viewer and therefore, mostly out of sight except for my pictures.
Mark, it's 4 feet and too far to reach. The high line has given me no trouble (famous last words), but the switch in front has been trouble and will be 42" away, again too far to reach. To make matters worse, there will be vertical things sticking up in the refinery to further block reaching in. I will be able to get onto the layout from the right side and lean into that switch. Because that switch sometimes doesn't cycle completely, I try and get a visual fix on its position. That will be harder with all of this stuff in front, but I'll manage. I may put a very visible block signal that will repeat the switch's aspect so I can see it from the control panel. The pushbutton on the panel also repeats the aspect, but it too is sometimes suspect.
