Wouldn't work since it was never ported over to tsw2 because it would have required a rebuild. The only other option is the mp15 and reskin into lirr and spawn it in or create a scenario
Then DTG should port it over, rebuild it, do whatever to get the little EMD switcher back in the game. Any other new piece of rolling stock will add to the value of the LIRR DLC, even a diminutive switcher. Devise a scenario with the SW pulling rakes of EMU through the washer or something like that or have it switch some Amtrak passenger cars around to bring that large coach yard alive?
