I did some more work on the train set. I animated two camera views. I have the tunnels and trestles. I think I will redo the trestles by using a path follower. The train tracks are made of multiple ties and short pieces of track that follow a path. The tunnels are made the same way. Right now the trestles are made from two pieces but don’t line up correctly so I should be able to fix that with the path.
I continued with another couple of Great Courses on DIY Engineering. I also gathered the parts for an ammo box radio. I think I should be able to pull it off.
