Commuting by train in Belgium is considered to be the most convenient, affordable, and reliable. However, knowing which platform to go to in Belgium at a train station is not a piece of cake. The following post will help you orient yourself to the train system in Belgium. The train in Belgium is run by NMBS/SNCB. Please check out their official website (https://www.belgiantrain.be/en).
To help you learn how to buy train tickets as well as acclimatize yourself to how the train system works in Belgium, you ought to download NMBS/SNCB Apps.
If you only wish to see the particular train route, you can use their website, Apps, or Google Maps. There are other whole bunches of Apps which you can use to see train routes and their availabilities. Personally, I prefer Google Maps. Nonetheless, that service does not work offline. Meaning you need to have data on your smartphone to access it.
That is the reason knowing Belgium geographically before you arrive comes in handy. What I mean is you ought to try to learn area names by heart so that it will be so easy for you to know which train you need to catch at ease. For instance, a train bounding for Hasselt from Brussel Airport normally goes past several stops like Aarschot and Diest, etc. Therefore, you should make an effort to learn most of the area names in Belgium.
As long as you are on the train, you are most unlikely to get a SIM Card (I recommend BASE_check out in CHALLENGES > Necessary Trivia > SIM Card) to access the data to see your live location on Google Maps Apps on your smartphone. As a result, before you go to Belgium, be sure to DOWNLOAD the map of Belgium on your Google Maps Apps so that you still can use and see your live location on that Google Maps Apps.
