and attach with CA. Run the chain to the right side of the brake mechanism through the trapezoidal bracket and the coupler platform, trimming as necessary to let the chain h ang loosely, and secure with CA. Place a .015 x .100 x 12" long piece on the bottom of the bracket extending to the coupler pocket. Make a small pad using .010 x .060 styrene cut 9" long. Place on top of these two angles, just behind the vertical brake beam towards the body. Now install the brake wheel on the brake mechanism. Install the diagonal braces and retainer valve with air line, and side ladders on the brake end. Then, install the ladder braces, end ladder assembly, side ladders, and diagonal braces on the non-brake end (see Photos 13-15.)


Completed GA-191.

Final Details before Painting
Install an eyebolt in each of the coupler lift bar bracket holes vertically after bending the eyebolt just behind the eye. Form each coupler lift bar by bending the end straight, a nd re-bend with a smaller protrusion to place in the coupler pocket cover hole. The coupler lift bar also has to be re-bent to create more of an offset. Install each coupler lift bar through the eyebolt and in the end of the coupler pocket cover and secure in place. Make sure the coupler lift bar does not stick above the coupler lift pocket (see Photo 16). I chose not to install trainline air hoses since I use the coupler trip pins on the Kadee couplers. If you are not using the coupler trip pins, install trainline air hoses now. InterMountain includes the trainline air hoses (labeled brake pipe assembly) or, as Jim Six suggests, use a Detail Associates freight-car air hose fit to an Athearn locomotive stanchion, cemented or pinched in place. Both classes had top cords extending over the middle seven bays. Add a Plastruct 1/16" angle x 21' 3" long to each car side,

Install the roof grabirons to the roofwalk by trimming off the mounting pins and securing in place. On the two cars I modeled, a tack board is placed at the bottom of the first panel. The tack board can be seen directly below the first two car numbers on each car side and do not appear to have been added to all cars. The tack boards are .015 x .080 styrene strip, 9" long. (Please note that the tack boards are missing from the construction photo as I did not notice these tack boards until I started decaling.) AccuFlex Primer Gray, thinned about 40% with 70% isopropyl alcohol. After priming, paint the primed cars with thinned Santa Fe Mineral Brown. I mixed two parts Maroon Tuscan Oxide Red and one part light Tuscan Oxide to create my Santa Fe Mineral Brown. After the paint has dried, spray with Testors Glosscote before decaling. The PS-4750s have a narrower rib spacing then Santa Fes previous Pullman Standard covered hoppers. From the prototype photos, it looks like all the lettering was narrowed to fit this new rib spacing, and I am unaware of any decals that properly match. Prototype pictures were used to match the lettering for each car and the decals used

Completed GA-191. Note the brake c hain running through the coupler platform, the center support angles for the roofwalk crossover platform, and coupler lift bar.
