In carrying out the master plan, NIS started building a new train station in the Tawang area which was built on 29 April 1911.

The shape of the building mass is a combination of cubes and beams, and the roof is in the form of a rectangular pyramid in the main lobby and triangular prisms on both sides.

The roof of the lobby building is crowned with a dome so that it gives the impression of being majestic, firm and solid which is characteristic of Indian architecture.

The doors and windows are ornamented in the form of rolaag brick construction, which is connected with ornate ceramic glazing, giving the building an artistic impression.
