Yeh dil maange more (RailFans, while ending their trip) - Kirti Solanki

I am planning to embark on a solo trip for fun next Friday. The route I'm taking is SBC-BSL-OKHA-DWK-DDR-LTT-KNW-AK-NGP-MAS-SBC. It includes an MG leg from KNW to AK. This is the first time I'm doing something like this, so I have a question. Is it OK for me to take photos on the platform or do I have to seek permission from the Security or Station Master every time? The reason I'm asking is that I was pulled up by a security policeman in SBHR station about 3 years ago for taking a picture.
