#1.  WHY???

#2.  ARE THEY???




  The track record of the builder is not as clear, although they may be an 
established transit or rail vehicle builder.       How many other systems 
are operating the vehicles Muni purchases?       How many other cities are 
operating the exact same Breda LRVs?       Given the operating environment 
I'm sure it's diesel buses aren't completely off the shelf either.
