His fm radio is already tuned to a fixed frequency (alloted by govt throught India - maybe the world by ITU) when he reaches the junction he will get brief info about the neighbourhood from the rail. At the same time someone is on the opposite footpath and also wants to go to Ceat building. He too walks up to his rail and recieves a different set of instructions to go to the same location from the Holy rail. As are others on different rails. One just waits a little to recieve the endlessly txd message. Each rail has it's own independent electronics not linked to any thing else.
Looks fine. And FM radios are most easy to buy.
