Menards Box Cars

These are all of my Menards box cars as of August 15th, 2024. The locomotive is a MTH Alco RS-3 and the caboose is also MTH. I am waiting for Menards to come out with a locomotive in my favorite road name before I get one however since they have yet to produce anything in my favorite road name, I am not holding my breath. I do like the box cars, they seem to be pretty close to 1:48 scale and most of the time, when you buy 11 of them you get one free after the rebate comes. Which railroad's Menards box car should I get next?

Did the Union Pacific run the RS-3 long hood forward?
