A girl who catches my train every morning who occasionally glances at me and smiles changed carriage and sat in the seat behind me. What does it mean?

Probably means nothing. I bet you don't sit in the exact same place every time you get on the train right? Maybe the carriage she usually likes to sit in was too crowded so she switched. I would not take that alone to mean anything if you don't even talk to her. If you do like her and she seems friendly and open to being approached then why not turn around and say hello? What do you have to lose? Really nothing. I doubt it is going to go anywhere if you don't try something and talk to her.
Maybe you should find out and talk to her :)
Could mean one of two things:
1. Her carriage was full, or
2. She hopes you notice her and would like you to say Hello.
Only way you'll know for sure is to say Hello and see her reaction.
It means she is in love with you and all you have to do is sneeze her way to get into her pants but you won't. lol
I would pretend your life is going to be over in 48 hours each and every day. This way you just don't give a shit and you'll talk to anyone.

it means she wants to seduce you , obviously.
I suggest you turn the tables on her and take her by force right there on the train tomorrow. She'll be flattered.
Let us know how it works out
If she made eye contact with you on the train and smiles she likes you. You are not good at getting hints.
do you have aspbergers/autism that may be why?
get checked being that bad is not normal
Dude, nut up and talk to her. Start easy with "Hi, I always see you on the train, my name is Jim". Odds are she will reply with "Hi my name is RIPYOURHEARTOUT". Than ask what she does and make small talk. If it goes well make it a point to get her number.
If she tells you to fuck off, just ride in a different train compartment... after you hide her body. 😉
You waited to long with a counterstrike?
I understood these days it has to be within the hour... oh wait that is social media. 😂
you won't know till you talk to her get some balls and say hello you don't need to ask us what to do.
Did it ever occur to you to talk to her? LOL
Doesn’t mean anything. She probably just wanted to sit somewhere and by chance the seat behind you was vacant.
she off to work at the sametime as you talk to her if you like her...
It MAY mean that she is interested in getting to know you. Give it a try.
She is getting prepared to strangle you!
Seriously? Ask her out. Duuuh.
that she found a seat.
It means you better start talking to her.
It means you want to sit next to her! 😂
It means you're now a stalker...
She might like you
Probably nothing
Too less signs to confirm anything , tell us more
So you are 30 going on 12?
It means she thinks that you look good
