Q1: As of now all the Hyperloop systems out there seem to be opting for a passive electrodynamic levitation system (EDS) From what I have seen at the SpaceX competition, literature and your first phase testing videos EDS seems to inherently have a lot of magnetic drag. An alternative would be to use an Electromagnetic levitation system (EMS) which Siemens used to build their transrapid maglev train (they also tried EDS at first but changed later in the development process).
While EDS might seem like a good choice at first because of its simplicity in the long term it looks like isn't the solution to go for (because of higher drag). As Siemens already proved, safety and reliability are not reasons for not choosing EMS, while it's performance is higher and it is a more integrated solution with the linear motor and also providing for power.
Have you considered using EMS and if so why did you choose to go for EDS?
Q2: Another question I have is about switching. It seems very hard to create a switching mechanism with your current suspension that would work at high frequencies of pods moving past. As it will probably require mechanical parts that need to move. Switching also seemed to be a problem at the SpaceX competition.
Can you elaborate on your plans for switches?
Q3: There is quite a lot of regulation on trains and the distance between them. What makes you think you can have vehicles at higher speeds with smaller time intervals between them? This will be required to acquire the necessary passenger flows if the vehicles are much smaller then trains.
