I have a good fleet of stored locomotives of almost any railroad and model from B&O F7 A-B-A set to a Southern SD24, a AT&SF SD45 to a BC Rail C44-9W. I used to just buy what I felt like getting. But my active roster is being saved for my future layout (when I can finally build a decent one!)
Bachmann:
-CR C40-8W #6104
-CR C40-8W #6108
-CR SD45 #6203
Athearn (blue box specials
-Conrail GP38-2 #8276 (my first model!)
-Conrail SD40-2 #6408
Athearn (RTR)
-B&M GP40-2 #302
-B&M GP40-2 #309
I also have some misc stuff from my dad's modeling years including Southern Pacific #7399, the SD44R (rebuilt SD45) in the daylight scheme, and some in his fictional railroad. Others include a MEC F3A #682 and MEC SW9 #334. (all of his stuff is Athearn.) He also has probably the first HO GP40X which he scratch built by putting together pieces from a GP40 and SD45 shell on an Athearn frame. Oh. Let's not forget a heavily damaged Rivarossi SP AC-12 cab-forward and my only working steamer, an Athearn Genesis 2-8-2 Mikado painted for Boston and Maine. Which I found funny because the B&M never owned a mike
Anyway, let's hear/see what you have.
