 Abstract:
   1624+3758, at z = 3.377, is the most radio-luminous BAL quasar known.
   It has several unusual properties:
   (1) The radio rotation measure, 183550 rad/m^2, is the second-highest
       known for any quasar.
   (2) The FeII UV191 1787-A emission line is prominent.
   (3) The BAL trough (BALnicity 2990 km/s) is detached by 21000 km/s.
   This may be a rare example of an object which is accreting both at a
   very high rate, and near the Eddington limit.
