What can you tell me about Chennai?
Are trains also used to import and export goods?
I don't know that but I can tell you a little about the climate. There are sometimes cyclones in the Bay of Bengal.
That is really old. Do you know if any wars ever affected the area?
Chennai is the gateway to southern India so tourists often land in Chennai and then visit the rest of the region.
