Spotting a Push - Pull Python Freight Train

While travelling from Delhi on the 12952 Rajdhani Express to Mumbai, I spotted a long Python freight train with locomotive in the middle of the rake. This could only mean that Indian Railways are now employing goods rakes in a Push-Pull configuration. Although, I was not sure at the time, whether the rake was two goods trains combined together for a common stretch of Journey or whether it was indeed a Push-Pull goods trains.
