How many here would be interested in an EMD GP40x?
Pretty cool locomotive; appearance-wise it's like a GP version of the SD45 with the flared radiators. Even though only 23 were made they ended up with some of the very popular roadnames modeled in O so there could possibly be market potential.
Here are the prototype railroads that had/have them, either bought new or acquired via mergers or purchase secondhand from parent roads (may have missed some):
SP, UP, SOU, NS, ATSF, BNSF & CP. Also Rail America, CF&E, TPW HLCX, & LSRC.
Offer them with the unique, experimental HT-B trucks (SP, UP, RA, TPW, HLCX, LSRC) as well as the standard blomberg-style trucks ATSF, BNSF, SOU, NS. (Some of the holding companies have or had both due to acquisitions from the respective roads)
For the SP, offer them with removable elephant ears so they can represent as delivered as well as later in their service life when they were removed. The elephant ears due to being involved in SP & EMD's early "Tunnel Motor" experiments.
High-short hood version for the SOU (now NS).
Here's some pictures with the popular prototype roadnames:
