Passenger yard completed - sortof

The passenger yard has been completed. It has 4 tracks spaced apart 2.5 inches to allow for easy handling. I am not making use yet of the track closest to the abyss (a drop to the floor). There is no barrier between this track and certain doom for the little HO sized people inhabiting the passenger cars.

I had in mind creating a wall along there using cheap 1" by 36" pieced of wood - better known as yardsticks. I even bought a bunch of them and painted them (rendering them useless as yardsticks). But I have decided that I don't like this idea. Instead, I am going to buy a bunch of girders by Atlas to form a wall with them. These plastic girders will each be held in place by 4 small screws so it will take a while to drill and insert about 100 of them. But I think it will look better. I have used this technique elsewhere on the layout.

I bought one package of girders last time I was at Caboose Hobbies, their last one on the shelf. I need 6 more packages of 4 to complete the wall.
