And, as can be seen in the photo, the fuse panel doesn't make for a very scenic or realistic background for an L train. In addition, the structure does block access to the panel, which is a no-no. But, since the track isn't attached to the main structure and track by the station, the whole track/structure combo can be removed in one piece. I may also just leave the door open to the panel, if the trains will clear the open door.
But, in the meantime, it's a bit distracting for a background. I may try a painted panel attached by magnets just to add a better color.
I use pretty basic ground foam as shown below:
Since the structure is visible from only one side, the following photo show how I only detail one side of the girder. This saves a little time and money in materials.
This is why I use Gargraves track ... the ties are solid wood when view from below:
The structure where it crosses the street is 1/2" higher than the rest of the structure on the layout. The track is level, but this section of benchwork is removable and the section was lowered so the door to the fuse panel can open when it is in place. It isn't too noticeable.
