I’ve got two NZR DH class locos for sale, $350 each. These locos are Frateschi U5B models with the correct cabs and battery boxes added, plus new cow catchers so there isn’t a big gap for the couplers, which I’ve also upgraded to knuckle-style couplers. One loco has large road numbers (902) and the other TMS numbers (2816).
If you’ve already got a Frateschi loco and want to correct it so it’s more of an NZR look-alike, you can buy the add-ons here.
