In order to get a good general picture of the overall punctuality, irrespective of the causes, it is preferable to look at the punctuality figures “before neutralisation”. Neutralisation means that no account is taken of delays that are caused by external factors and/or major investment works (GEN, etc).
With reference to the punctuality figure that "is weighed on the basis of the number of passengers ", the delay of a train carrying a lot of passengers outweighs the delay of a train carrying fewer passengers.
The punctuality is also measured "along the entire travel route": thus, not only delays as regards the trains’ arrival at their final destination are taken into account, but also the delays experienced along their entire travel route.
Number of assured connections
Infrabel monitors how many scheduled connections (with a transfer time of minimum 3 minutes and maximum 20 minutes) are effectively realized in the country’s 10 most important transfer points.
Punctuality according to train type
Punctual train arrivals or arrivals with a delay of no more than 6 minutes 
Cancelled trains
Cancelled trains (did not depart or restricted to only a section of their scheduled route) are not included in the overall punctuality figures but are counted separately, and the reason for their cancellation is mentioned as well.
Parties responsible for the delays and the cancelled trains
Various actors play a role in the punctuality of train traffic. Generally speaking, however, the parties concerned are the railway network manager (Infrabel), the respective operators (e.g., SNCB), and third parties.

Summary of the major causes for delays
- Damage to rolling stock
- Damage to the infrastructure / signal box
- Incidents on foreign networks
- Evil intent, vandalism (e.g. cable theft)
- Weather conditions (e.g. problems as a result of winterweather)
