All these questions are answered in the original proposal sent out by Elon Musk. Please do yourself a favour and at least open it. It is a long document, but there are many things to consider, and this document addresses most of them. It explains how they will manage safety, what happens if the train stops, how they will achieve the vacuum etc. Not in detail, but enough to make sure it is practical. These guys wouldn't build a full scale test track if they weren't at least sure it would work and be economical.
The document is well worth the read, and there are a lot of calculations and simulations in there to prove the concept.
