15 (SCT class), 9 (LDP class), 25 (TT class), 3 (WH class), 9 (GWA class)
Vinnybarb/Ghosty,
Further to that, UGL are building two models of locomotive at the moment:
C44aci/C44acHi (where the "H" designates "heavy" for those locomotives limited to the NSW Hunter Valley) including the XRN Class, 6000 Class, 5020 Class (H) and 92 Class.
Cv43aci including the AC (4300), ACB (4400) and 6000 class locomotives.
I'm unsure of the model numbers of the new CEY and CF classes being built at the moment.
As for the EDI builds,
V544(PN), Q301-Q319 (ARG) and FQ01-04 (GWA) are all GT46C (similar to the TT/SCT/LDP/GWA/WH classes, which are GT46-ACe). Obviously the body shape differs slightly between the classes, but the basic model is the same.
As for photos of the roof's, I'll have a poke through my collection and see what I can find, although I'm making a trip to the Hunter on Friday, so if an oppertunity presents itself, I'll have a crack.
