Because I can't find charming and good words to say about this, I'm just going to get to the point here. We have some BN stuff and while there are a few predecessor dlc addons for TSC, we're missing a lot of predecessor content for the BN content we have and we could use some more BN content as well. Picture this, a CBQ SD24 and a BN SD24, running on Steven's Pass, Feather River Canyon, and even Marias Pass, with some good BN and CBQ rollingstock, hell maybe even throw in some Frisco rollingstock. I'd like to think that a BN SD24 pack (that's not developed by DTM, HIS or even DTG) would be so very appropriate for the BN-based routes we do have, along with the route that weren't owned by BN, but did see BN activity. I can't even imagine anyone saying "No" to an adorable little engine like this. Just look at it, it needs attention and most importantly, it needs TSC players who want to run this damn thing till the wheels fall off.
A Santa Fe version would be awesome on Cajon or Seligman Sub. We could get a UP version for Sherman Hill or Cajon Pass, too. ATSF rebuilt their SD24s into SD26s with electronics upgrades and upgraded prime movers.
