I plan on using the car card and waybill method of moving cars from one location to another. When cars are spotted at an industry or in a yard, there is a need to store the corresponding car cards and waybills nearby to keep track of the cars. As I have mentioned before, I have already compromised my original druther of 36 inch aisles. As a result, I am continually looking for ways to minimize any intrusion into the aisle space. One of the best way I have seen is the use of car card boxes behind the fascia in the manner that Rick Fortin has on his layout.
I had built the boxes before and just needed to cut some additional holes in the fascia and mount the boxes behind the finished holes. I hope the following series of photos adequately demonstrates the process followed.
I also added a strip of plastic to hold car cards when they are being sorted. The strip is trim for holding FRP and is available at home improvement stores. It is visible in the last two photos above. I also am using some "J-bar" from Tap Plastics - http://www.tapplastics.com/shop/product.php?pid=155&
Both seem to work OK. Here is a photo of the clear J-bar just visible at the top of the fascia parallel to the track. Click on any of the photos for a larger view.
