I paint and decal the car. Cut a piece of scale lumber for the running board 42'-0" long (this can either be milled running board or built up from scale lumber). Trim the latitudinal running boards to seven full boards. Cut four pieces of 1/32" x 1/16" basswood 3 '-0" long. Cement 1/32" edge 1/16" inset on the under side of the latitudinal running boards. Add roof grab irons of .020" wire. I paint the running boards with the same mix of mineral brown is use for spraying. Dip the car in alcohol to remove the oil and grease from handling during assem bly. Spray the car with Barrier or Shield coat. When this is dry, spray it with mineral brown. (Mineral Brown can be mixed with equal parts of Tuscan Red and Box Car Red.) After the entire car has dried, a good semi-gloss to clear gloss coat should be used to obtain a good decal base. Decal the car with Champion's curved map set (available from Marketing East, Inc.) as shown in the photos. After the decals have completely set, give the car a flat to semi-gloss coat to protect the decals. Install the running boards and weather the car to your preference.

Cement the floor to the car body. Cut two pieces of .015" ABS or styrene 1'-0" x 39'-10". Join these, one per side, to the flange on the car floor. Cut two more pieces 8" x 39'-10". Join these to the outside surface of the other two pieces. This forms the inset side sill. After the joints have set, sand or file the bottom edge flush with the polling pocket tabs. Cut twenty pieces of Plastruct 3/64" "T" section 3/16" long. Cement one of these below each rivit line and door post. After these have set, trim them flush with the bottom of the side sills. (I find a pair of Lambert Rail Nippers ideal for this.) The end ladders are a Con-Cor product. Use ACC cement to attach them to the ends. The car has an Ajax brake housing. Use ACC cement to attach a Cal-Scale housing to one end cenetered about 1 '-4 " from the centerline of the end. Below, center a brake step 10" x 30". Form a

vertical handbrake rod from .020" brass wire. Cement this to the end of tha chain on the Cal-Scale casting. Cement sill steps on the four ends of the side sills. I used Con-Cor sill steps; NWSL also makes a fine sill step or you can form them from .010" x .030" brass strip stock. Install couplers of your choice in the underframe. Cut off the projection on the bolsters as the correct trucks for this car are Kadee Andrews. Also, it helps if you first tap the holes in the floor with a 2-56 tap before installing the trucks. Install the kit supplied weight. Trim the ends of the bolster to fit inside the new side sills. Install the modified under frame and trucks. Check for coupler height. Install the doors and upper door guidee. Clean the air reservoir to the basic cylinder. Flatten half of one head to take a .010" mounting bracket. Cut a piece of .010" styrene 1'-0" x 1 '-3". Cement this to the short part across the head, then cement this to the inside of the side sill 10'-9" from the A end on the right side. The running boards for this car are wood. The parts for these can be made now, but I don't install them until after
