Video on demand is gaining ground, and in a big way. PressPlayTV – a video streaming app has introduced its services on Indian Railways. Passengers will be able to access songs, movies, news and other video content over WiFi hotspot in the trains. The service is free of cost, and is initially coming up on two trains in the Northwestern division. The app will automatically download once a device is connected to the train’s WiFi network. The video contents can be live streamed or downloaded to the app.
