rail has been deemed by a majority of the people to be necessary.  yes, it has become expensive due to cost overruns.  but the fact is, it must be built now and any bus system would be inadequate (wholly).  Our current bus system supposed to be the best in the nation but how may of our people think so?  If it were so great, why did people decide to build rail?  to wait to build later would even be more costly.  if rail was built when it was first proposed - maybe $2B, 20 years later $10 B, wait another 10 years, probably $20 B.   you antis are only thinking shallow, too expensive, scrap it.  the rail besides transportation have many other collateral benefits and are just as important, if not more than the transportation benefits.  affordable housing, reduce the need for cars, quality of life issues, etc.  how do you measure these benefits in term of dollars?  much more than $10 B.  hence, you antis are narrow-minded and selfish, totally.
