Jamaica Training Aid Practice Test

The idea is that railways separate tracks into those that serve passengers at platforms (station tracks) and those used for through traffic (main tracks). Main tracks pass through the station and are used by trains that don’t stop to board passengers; they aren’t paired with platforms. Station tracks, on the other hand, are the ones next to platforms where trains stop for boarding and alighting. So, the tracks that aren’t station tracks are the main through tracks. These two tracks handle through-running and bypass the platform areas, which is why they’re not considered station tracks. The other options describe pairs that involve tracks with platform access, which are station tracks, not the through/main tracks.
