I agree, we certainly could use some more of "Big Blue." Searchlight Simulations already has made a fantastic SD40-2 in Conrail Quality paint. Here is the link if you want to check it out. JR SD40-2 Conrail Quality | Searchlight Simulations (searchlight-simulations.com)
Absolutely. I'd suggest the following locos: SD45-2, SD80MAC, C40-8/C40-8W, SD70MAC, C39-8, SD40-2, and GP38-2.
