Of course, Legacy and Steam Whistle would be nice. But here goes:
1) C&O 614
2) NKP 759. They should have everything "left over" from the 779 and 765....just change the cab number and the sound effects specific to 779/765/759...but don't use the engineer with the New York accent. (Rich Melvin maybe?)
2.1)Heck....reissue the 765 w/better steam effects.
3) Re-issue the Milwaukee Road 261 since I completely missed the boat on that one.
4) How about a reissue of UP FEF 844....just "throw in" some new steam effects. It's one of their best locos ever....IMHO.
The tooling for 2-4 has already been created. Am I asking too much?
Oh well....just some thoughts.
