In April I had traveled by the MAO-CSTM Jan Shatabdi and after Ratnagiri, I observed a long tunnel, so long that the train took nearly 5 minutes to cross. At that time, I didn't knew it was that Karbude tunnel only but the experience through the tunnel was wonderful. The Jan Shatabdi covered the tunnel with such high speed that your ears begin to pain (sort of pop out) due to change is air pressure.
