When Cane Creek and Sherman Hill were released the UP AC44 and the SD70ace subbed in at SPG. Latest with TSW3 release the UP stuff was removed. The explanation was, that it was more UP stuff than in real. But since TSW5 that explanation is overhauled. Because now everyone who thinks he don't want "the unauthentic" UP stuff can delete that UP layer and play with the CSX stuff only.
