Modeling municipal waste trains, Part III: spine cars
The door closure on the left side (left) is a long, triangular styrene strip that fits between the upper and lower rails. The
sign. Both designs feature a removable tarp to cover the load contents while a car is in transit. To begin constructing the newer, re- vised style container begin by cutting side and end walls from .015″ plain styrene sheet. Make the cuts into 6′-0″ high strips and then cut them further into 20″ and eight-foot lengths. Due to the number of pieces required to make multiple containers, fabricating a cut- ting jig for all the required pieces will help speed construction. A simple jig can be made from thick styrene sheet and strip.
The remainder of the container con- struction focuses on using styrene an- gles and strips to join everything to- gether. Cut four .060″ angles six feet high and cement one to each end of the 20-foot side walls. After these have dried, the end walls can be cemented into the angles, forming a rectangular open box. To add the upper and lower rails, cut two .100″ angles and two .015″×.060″
hinges on the corners of the container and the rear door (right) and are made by folding pieces of styrene strip.
styrene strips to fit between the up- right angles along the sides. Cement the angle along the bottom of each wall and the strip along the top. To com- plete the front wall use .060″ angle at the bottom and a .060″ strip along the top. Once the lower rails have been at- tached, the styrene floor can be in- stalled to help keep everything square. The rear of the container is similar to the front; however only strip styrene will be used. Cut two .015″×.060″ strips to fit between the end angles and cement the first at the top of the container. The second strip should be cemented in place three scale inches from the bottom edge of the container to allow room to add brass wire which will represent the door hinge. The next step in constructing the container is to add the side ribbing. Styrene strip measuring .015″×.100″ is cut to fit between the top and bottom rails of each side and end of the con- tainer. When cutting these three differ- ent lengths are required, one for the

sides, a second for the front and a third for the rear.
The three side ribs can be cemented to
the container using a spacing of 57³/₄″ centers beginning at the inside edge of the corner angle. Each end has two up- right ribs, mounted on 24″ centers from the inside edge of the corner angles. With the basic container body con- structed, lift posts can now be added to each corner. Cut .040″×.060″ styrene strip into ¹/₄″ lengths and cement these to each lower corner, covering the ex- posed ends of the angles. This allows the strips to extend beyond the contain- er body. Once these have dried, cut them off flush with the container body using a No. 18 hobby knife blade placed along the container body. After the low- er posts have been added, turn the con- tainer upside down and repeat this for the topside of the exposed angles. Once all the posts have been added, dimples representing the holes used for lifting the containers can be made using a No. 69 bit and drilling the dimples at the
sures can be placed on both sides of the end and ratchets can be made from Grandt Line turnbuckles which are cored for wire.
