The edge of the platforms at Pune Jn now host a water line with quick disconnect couplings at regular intervals. The cleaning crew couple a hose to this line to clean the toilets with rather than use the diesel engined water pump which was used previously. This is Pune's pf 1 and the train in the background is 2780 Goa Express. I wonder if the water line has a pulsating flow like the diesel pump. The pulsating flow is essential for an efficient cleaning. 2006-02-03
