I am glad you asked.
You asked "The red, white, and black switcher; what road is that? A striking loco."
Post 21 on page 2 of this topic (quoted below) explains this engine.
"I had a Marx 1998 switcher missing the shell. I found a Lionel SW2 shell and cut out about 1 inch of it to shorten to fit the 1998. I painted it black, white and red in the colors of ALCOAs Bauxite and Northern short line railroad from the Bauxite, ARK alumina and chemical plant in Bauxite, ARK to the a major railroads main lines. The Marx1998 is a great running engine and always beats other engines in racing through the oval and figure 8."
