Hey TrainSim-Adam so, the throttle on the NTP class 47 is VERY wrong, the BR Green version had a "smooth" throttle (0-100%) but the specific BR Blue version on NTP should have an 8 or 10 notched throttle handle with A distinctive CLICK between notches, I know this as I have had a cab ride on several Class 47 locos, both Green and Blue, and the blue ones always had notched throttles. Maybe you could look into this as it seems DTG have reused the WSR 47 cab for the NTP 47 whereas the throttle needed notching, This could be easily remedied as I think this is a MASSIVE immersion breaker.
