Yeah exactly. The only classes that are a bit more complicated and probably would be worth modelling separately are the DXB’s, the DXC’s, and the DXR’s. The DXB’s are the standard design with ‘Brightstar’ wheelslip control. The DXC’s have more powerful engines and extra air intake chutes for operating through the Otira Tunnel with the main coal train’s. And the DXR’s have the same engines as the DXC’s (I think) and new cabs.
