What about platform no of a train or coach position? Platform no will often be available only 15 minutes before arrival. And I don't think coach position can be queried online either...
Once you are on the right platform, look up. There are boards that have numbers like 1, 2, on them, and in small letters, below them, the coach number.

But only in very few stations, right? And you should be on the right platform in the first place, which defeats the whole purpose, because you can know the coach position a lot before you can know the platform. ie when the train starts as opposed to just before arriving at a station..
