Bogie Mechanism: Possible Solutions

I decided to be part of the Bogie mechanism team due to some critical flaws the current design has and I am looking forward to what could be improved on it. I decided to read further into the 2014-2015 project report and from what I have read, the Bogie mechanism is engaged to the guideway by switching mechanisms that are installed on the top and bottom rail. Although the design worked, it did so sluggishly. Because many podcars will be travelling on the same track in the real world, the current design proves to be time inefficient and will cause delays.

One problem with the current Bogie mechanism is that it generates a lot of vibration and noise which hampers the smooth ride passengers expect. Because the Bogie mechanism will be subject to many types of forces (i.e. friction, rolling resistance), a possible solution is to come up with a damper mechanism that can be mounted between the wheels and guideway to reduce the effects of the forces the passengers will experience.

Also, the thing that is bothering me is that only one side of the bottom outer wheels is engaged to the guideway while the other side is freehanging. A solution needs to be thought of to have both sides engage to the guideway.
