Do you work for GE or EMD (Formely GM EMD)? Both of their 4 cycle diesels are hush/hush and they frown upon public pictures of their componentry because they are so competitive with one another. So I would highly recommend NOT posting pictures. I just so happen to work for GE during the day.
I'm an EMD fan personally, but GE signs my paychecks, so...
You can post pictures of either EMD'* "H" motor, or GE'* GEEVO'* (Evolution Series) engines they post on their site, but not what you take personally!!
Also, no diesel/electric locomotive in service by a road carrier (UP, BNSF, etc) has a supercharged locomotive. All are turbocharged V12'* and V16'*.
