mounted at the rear of the tanks in the center completes the frame. The truck frames all have indentations between the axles. These should be drilled out for improved appearance. All units have a speed recorder mounted on the right front truck frame on the rear journal. Drill the journal and mount a Utah Pacific speed recorder with some cyanoacrylate adhesive. All the SD-9's equipped with dual cab controls had two control stands, so mount a speed recorder on the left front frame on the center axle. Use some insulation from a grain-of-wheat bulb to represent the recorder cable from the journal to the frame. That completes the undercarriage.

Wash all parts in hot water with deter gent and air dry; give all parts a coat of light grey primer and check for any blemishes missed before. The grey will make them very easy to see. Correct any problems and give another light primer coat; this step really helps in eliminating imperfections in the finished model and makes final painting simpler. It's easier to cover a grey base coat than black plastic. See Table I for a guide to the paint schemes worn by the locomotives. The table gives a run down of the appearance of each unit as of the BN merger on March 2,1970. All units, except C&S 831-842, were delivered in black and grey, with red and grey end stripes, and red and yellow sep aration stripes and sill striping. C&S 828 was the first unit to wear the red and grey paint scheme. It was repainted in that scheme following wreck rebuilding by EMD in March,1959. C&S 831-842 were delivered the following month and all subsequent orders and repaints got the red and grey paint scheme. Even though the first power with all white frames appeared in 1965, when re painting units the red scheme with the 5" white sill stripe was used up until late 1968. As a result, relatively few older units received all-white frames or, in the case of the SD-9's, white access doors below the walkways. Apparently, only one unit, Q 361, painted in Denver, Colorado, in November, 1968, received the red scheme with all-white access doors and black pilots. See Table III for the paints to use on your unit. All handrails,ladders,uncoupl ing levers and grabirons, except for the grabirons on the roof, were painted black. The underbody and trucks were also painted b1 ack. Units in the original black paint scheme had the fuel gauges painted yellow. All detail on the roof was grey, including the grabirons; the only excep tions were the spark arrestors which were black.

After the unit has been painted and lettered, use a very small amount of cyan oacrylate adhesive and attach the end ladders and the all-weather windows (if desired). Apply some light weathering along the underframe and trucks and around the pilots; your unit is ready for work.
