manny the AAA200 derailed on his first day and was then split into these two, however there wasn't enough scrap metal lying around to finish them, sooooo... yes they are based off of @Brandonthecubanmogul 's Sergey and Artyom P36s.
@Brandonthecubanmogul for inspiration Someone online for making the AA20 in lego as a 4-6-8-4 (like these)
