(Portland, OR)  --  The union representing drivers on MAX lines blames TriMet for ordering a train to drive through standing water.  President of Amalgamated Transit Unit 7-5-7 Shirley Block said yesterday the driver of the car under the Morrison Bridge was told to slow down but drive through several feet of standing water during Halloween's storm.  TriMet says no manager ever gave that order to the driver.  TriMet is investigating the incident along with the O-D-O-T.
