The most common way in which I understand this American expression is ‘at a later time/date’. The reason I give it this meaning is because in BE (at least in Australia) ‘down the track’ is used in this way - eg:
‘I fixed it for now, but it might still break sometime down the track.’
‘I didn’t see him to-day, but we’ll catch up down the line.’
