      A simple tranfer equation in an arbitrary coordinate system specified by a differential equation for transfer elocity is considered.
      Questions of transformation uniqueness and transfer equation evolution in an arbitrary coordinate system are discussed. Two theorems are proved approving the former question and providing sufficient conditions on equation coefficients for transfer velocity maintaining velocity for the latter one.
