New Fail Safe Mechanism

As per Professor Furman's input, we met again to determine a new fail safe mechanism that would catch the bogie and cabin and keep it from falling off the railway in the case that the steering system failed.  The biggest problem we had when addressing this situation was determining how to create a system that wouldn't change the guideway or the bogie much.  Most of our ideas stemmed from adjusting the guideway, which was greatly discouraged.

After a lot of drawing and discussion, we were able to create hooks that wouldn't require any changes to the guideway and would be able to catch the bogie if it fell in a diagonal and/or downward motion.  The hooks would be attached to near the top of the bogies, to hold on to the guideway if it went diagonally.  There would also be hooks on the bottom that would catch the bogie if it fell downward.  The hooks on the bottom would barely be above the guideway because we needed to keep the displacement low so the impact load would be low, which will put less force on the hooks so they don't break off.
