Indian Railway Catering & Tourism Corporation [IRCTC] — The falsely accused and fired me for ticketless travel

I had booked a 2A ticket from Bangalore cantonment (BNC) to LTT for 11th of Oct 2016 for train number 11014. Scheduled time of boarding was 4:10pm.
I arrived at 3:40pm and saw that the train had already arrived. The announcement and all indicators confirmed that the train was precisely what I had booked:Mumbai Kurla LTT express to Mumbai. I also asked passengers whether the train was headed towards Mumbai. They said Yes. So I boarded the train and occupied my confirmed seat. But to my surprise, the train departed early and headed towards Bangalore City and then went headed back towards Bangalore Cantonment.

At this point, the TTE came to check tickets. I showed him my identification card. But he wasn't interested. He demanded a fine for travelling ticketless from BNC to Bangaor City and back. The fine he said was Rs 650 (for one way ticket in a 2AC from Cantonment to Bangalore City)x2 (for fine) for one way (Total amounting to Rs. 2600). Although shaken, I told him politely, that I saw that it was my train: Train no. 11014. He denied that it could have shown train 11014 and said that it is 11013. and kept demanding money in front of fellow passengers. He mocked me for believing that a train can arrive early and laughing with other passengers said that trains only get late. He then rudely demanded the money again. I did not have that much money (which is beside the point). Finally he said that, and I quote, "Since I am a human being, I will charge you a fine for general class w/o ticket which is Rs 400." I gave him Rs. 400. I told him that I did not break any law. Again, rudely, he said that its because of him being a human being he charged me less instead of the whole amount. Threatening me with a bigger fine, he walked away.
My fellow passenger said that this is a regular practice. He would see this with every trip: The train arrives later than passengers; they board the train, the TTE humiliates and fines them for boarding a train that goes in the supposedly reverse direction.

It is very cheap of the TTE to hand out some target number of fines. I have witnessed a man harassing a woman on the train, to which a TTE maintains silence, because such is a lesser crime in the eyes of the IRCTC.

My experience was humiliating to say the least.
