Project Details:

​

• Train Assembly is a combination of new parts and the Bogie Assembly.

• Please note that train design is purposely simple in attempt to keep the file size down for the file motion study. Only the main idea and mass was captured.

• There are a 2 different degrees of freedom / movement that are built into the assembly, mainly centered around the bogies.

• The bogies can rock back and forth (like a see-saw) and rotate via two sets of pins that are used to connect the bogies to the body of the train.

• That way, in theory, as the track turns and rises/ falls the bogies have the motion ability to hug the track at all times. While this is not seen the final assembly for simplicity, the ability is built into the design – which I felt was important.

• The train assembly also includes the chain dog (body and pin) that will have a solid body contact with the anti-rollback rail to create a safety feature that prevents the train from rolling backwards.

• Restraint systems are not in scope.

• Assembly has 14 concentric mates, 14 coincident mates, 7 parallel mates, and 1 limit angle mate that was used to ensure the chain dog could only move up into the body of the train and note swing down into space.

• The mass of the train is so high because in real life, each train would have close to 8 or 10 rows / cars, whereas I only have one. I wanted to bring that weight into the track, so I did not override it and used a large block of an aluminum allow to simulate this.
