Finally reached. Nice isolated station. Pitch darkness all around, and raining. There was a powercut at the station. The lights just returned.

The journey was an experiment to see if there is a viable train route from centre of Bangalore to the extreme south of Bangalore. And the conclusion is: yes. The train journey is very relaxing and safe ... and cheap Rs. 10!!! But due to the very low frequency of trains, this is not a popular mode of transport.
