That would imply we have a policy and that we think.  I believe,  
Boris, you are giving too much credit.  Transit tends to be knee jerk  
and reactionary.   It isn't policy.   It's simply that we haven't  
spent the money to fix anything and now we're caught with our pants  
down so we have to downgrade the equipment to provide any service at  
all.
