M-K-T "The Katy" SD70ACe Diesel Heritage Set w/Proto-Sound 2.0
This is probably my favorite of the 7 Heritage sets that MTH made for 2007. The bold red and the star on the front are just plain cool. The sound effects are equally as cool. You can check out a video of this engine in action right here. Made in 2007, added to my set in July 2007.
