According to you Bombay - New Delhi Duronto is a West Bengal Train . Similarly , Madras - Trivandrum Duronto or Ajmer - Delhi Durontos are also West Bengal trains . For your kind info Sir , not a single train for West Bengal (esp Calcutta) was alloted by RM Ms Mamta Banerjee in her Rajya Rani Express trains list . Tell me one thing , isn't West Bengal a part of India or IR ?? Such statements issued by people like you are very hurting and Anti West Bengal . Take care , Sir Ji . Thanks .
