It's not quite as simple as that. Railway station platform arrangements differ by country, and sometimes even within countries. In Britain, where railways started, the invariable convention is (and has been for about 150 years) for stations to have 'high platforms' that are 36 inches (915 mm) high. This is near the height of the train coach floors, so that coaches only need a small step at each door, or none at all. Some other countries have platforms that are much lower, or even none at all, so that passengers board trains from ground level. In these cases, there is some kind of step arrangement. Some countries (e.g. France) have a mixture of high and low platforms (The Paris Métro is high platform, whereas most above-ground SNCF lines are low platform).

Here in Britain, we talk about 'getting on and off the (or a) train', and we would do so whatever the height of the station platforms, or even if there weren't any. We also 'board' or 'join' trains, and 'alight from' or 'leave' them.
