  No it doesnt have differential, thats one of the reasons of the wastage of the train wheels.

  so please will u elaborate that how it performs turning along curves...?

  I think, turning of train radius is kept large so that if you see small part of curvature it will look like straight line.
  
  & yes this is the main reason for reduced life in train wheels & rails.

  The train wheels are formed like a truncated cone attached to guide flange.The diameter of the wheel closer to the flange is slightly bigger than the outer edge.
  
  The wheels are fixed on the axle in such a way that the flanges run adjacent to the inner face of parallel rails.
  
  While traveling on a straight route both the wheels will be in contact with the rail at the mean diameter point of the wheel.
  
  When the train is negotiating a curve , due centrifugal force the bogie is pushed away from the centre of curvature.
  
  The bigger diameter of the outer wheel and the smaller diameter of the inner wheel will be in contact with the rails when negotiating curves.
  
  The outer wheel with bigger dia contact covers longer distance, while inner wheel with contact at the smaller dia covers shorter distance.
