No manual exists for the Class 33 DLC for TSW2018 or TSW2020. There is no Class 33 manual available in the game, or online at the DTG website, or on Steam, for this TSW DLC. To be fair - the Class 33 is easy to drive, and shares basic features with the Class 47. But it is probably the best locomotive designed for the game, with the most fun features - DTG should make it one of their showcase locomotives, and provide a manual for it. It's in the 2013 Rail Simulator manual...! Congratulations should be given to everyone that worked on the Class 33, including the visuals, the lighting, the audio, the animation, and the physics. It was actually worth buying as DLC, even though it should obviously have been a standard part of WSR, as it was in 2013. But can we please have a manual?
