Just as a sidenote, let me tell you that in Colombia the expression
"Te dejo el tren"
is frequently used to mean that time has passed for you, and the precise context in which used is related to a person's marital status.
If to or from somebody is said
Lo dejo el tren
it means that for that person that the probabilities of getting married are low, mainly because time has passed and is getting old.
Keep in mind that this expression has a wide array on less educated populations where getting married and early age and giving birth to child is a very important issue and not getting married is seem as a woman's or man's failure.
