I have been wanting to repaint a tank car in the Union Pacific Yellow. The tank car is painted primer right now but i need to know what colors i could mix to get the yellow that the UP uses for their locomotives. I am going to run the tank car in-between a GP38 & a FP45 or it is a FP40 not to sure (both are UP Locomotives) cause these units will be placed into helper service until i can purchase a couple of SD40-2's & SD45's. Any advice will be helpful. Thanks in Advance. P.S forgot to mention that it is a former Hooker Tank Car so it willl not be the the ones that the UP had for their turbine locomotives.
