Agreed!       This is the thrust of my comments below  --  modern lrvs 
just an extension of  Already  Existing  Transit  Technology    ----    
so why the arduous month long // xxxx mile Non Revenue operations for 
Each And Every Vehicle purchased???????       My original observation is 
that  Off  The  Shelf  Siemens  equipment goes through shake down 
testing before entering service like  <--Specially  Built  Bredas-->  in 
San Francisco.

Track Not Necessarily The Problem.       Monomotor design of Siemens 
truck seems to be the culprit as detailed in press releases and Trolley 
Fare articles    ----    Boeing used mono and weren't any problems 
specifically attributed to that.       Siemens used elsewhere in  U.S.A. 
// Canada without  <--problem.-->
.
<--Problem-->   Is,  However,   that Siemens equipment has tremendous 
affinity for  <--Hunting-->  as it heads down the tracks  --  lateral 
oscillations that increases with speed.       Have experienced this on 
virtually every Siemens system I have ridden as has local Rail 
Aficionado Harry Peat who has ridden far more than myself    ----    
other equipment, such as UTDC in San Jose and Bombardier in Portland, do 
not exhibit such problems.       Indeed, even the New Low-Floor Siemens 
cars in Portland, OR, exhibited this potential  When  Brand  New!       
Haven't been back to ride since then.

Disc brakes on Siemens have a tendency to chatter during application 
making for a rough stop.

Siemens // German // European equipment  Not  Without  Problems  of 
their own!
