'Track' isn't so bad, in German-speaking countries they tend to use 'Gleis' which translates to 'track'.
It normally quite literally *is* the track, though - if you had a station thus:

where the #s represent platforms and the =s tracks, in Germany they would be numbered 1 and 3, while in the UK odds on they'd be 1 and 2. If you take Manc Picc, in Germany you might well have 1-12 and 101-102 for the satellite bit. You get all sorts of odd variants.
The more interesting one is the one you get in eastern European countries, where both the physical platform islands and the tracks are numbered. Often only the island is shown on the PIS, so if you have...

in the UK and Germany they'd be 1 and 2, but in the Czech Republic and Poland (at least) they'd both be 1, with tracks 1 and 2, and the PIS would say 1 for all trains (sometimes, but not always, with the track listed as well). In the Czech Republic they avoid some confusion by using Roman numerals for the islands and numbers for the tracks, but in Poland not always!
