To find out more about the expected crowd level in your train, register your trip with Treinwijzer in the NS app (and don't forget to update the app first). As more passengers register their trips, the more accurate our predictions will be. Together, we can help as many passengers as possible travel safely and responsibly. Scroll down for the Treinwijzer terms and conditions and all FAQs about registering your trip. Trip registration is not compulsory.

How does the Treinwijzer work?

Register using an NS account

To register a new train trip, you will need an NS account. If you don’t have one already, it's easy to create an account. If you have a Mijn NS account or Mijn NS Zakelijk account, you can also use this account to sign in.

List of registered trips

As soon as you’ve logged into the Treinwijzer, you’ll end up on the ‘My registrations’ page. Here, you can find a list of future trips and register new trips. When signing up for a trip, you can check crowd levels in the train by means of the crowding indicator figures and see whether there is still space left for you (and your bike, if you’re bringing one).

Useful to know

  • You can only register for a trip that you want to make today or tomorrow.
  • You can register for a train trip up to 1 minute before the train is scheduled to depart. You can only register for train trips today and/or tomorrow.

  • The Treinwijzer only works for NS and in domestic NS trains.
  • Children up to the age of 4 years can travel on the same registration if they ride on your lap. Each traveller older than 4 years can be individually registered for a trip.


Frequently Asked Questions

  • The Treinwijzer in the NS app isn't working. How can I register my journey?

    The Treinwijzer in the NS app is probably not working because you still have an old version of the NS app on your phone. Update the NS app, and then try again to register your journey.

    iOS users should install version 7.8.0. or newer.

    > Visit the App Store

    Android users should install version 6.1.7. or newer.

    > Visit the Google Store


  • Am I obliged to register my train journey and/or my bicycle?

    No, you are not obliged to register your train journey and/or your bicycle. You can also travel without having registered. However, we do ask you to register your journeys.

    This enables us to inform you if the expected crowding increases, or if your train is cancelled. In turn, we – and you as traveller – can see in advance how crowded the train is and whether there is room for you to take your bicycle.

  • Why must I log in with an NS account to register?

    We need your e-mail address so we can inform you about your registered journey. You will receive an e-mail from us to confirm your registered journey, when you cancel your journey, and if your registered journey is cancelled due to a disruption or malfunction. For most travellers, this e-mail address is linked to an NS account. If you have a Mijn NS account or a Mijn NS Zakelijk account, you can use this to log in and register journeys.
    If you do not have an NS account, you can easily create one. All you need is an e-mail address and a password that you choose yourself. After creating your account, you just need to confirm your e-mail address once to be able to log in.

  • Do I need a new NS account for each journey or bicycle registration?

    No, it is not necessary to create a new NS account for each journey or bicycle registration. If you are travelling with a group or wish to register more than one bicycle, you can do so on the same NS account. However, you must go through the entire process for each registration. Following the first registration, simply look up the same journey and register it for a second time, and so on.

  • Why can I only register a train journey for today and tomorrow?

    You can only register a train journey for today and tomorrow because we need to know for sure which rolling stock will be used before we open the registrations. The deployment of rolling stock is finalised about 36 hours in advance, and it's only then that we know how many travellers can go on a particular train.

  • Is my registration a ticket?

    No, your registration is not a ticket. You travel in the usual way with your OV-chipkaart or with a separate ticket (such as an e-ticket). If you want to take your bicycle with you in the train, then register it, and remember to purchase an Off-peak Bicycle Ticket. These tickets are currently only available online or from the NS OV Service & Tickets counter.

  • Does a registration give me priority on a crowded train?

    No, registering for a journey does not entitle you to travel on the train for which you have registered. The same applies for registering your bicycle - a registration does not entitle you to take it on the train. You can only take your bicycle if there is space for it and you have a valid ticket.{br1} {br2} However, registering your journey and your bicycle will give you insight into how crowded the train is and whether there is room for your bicycle.

  • What happens if all or part of my registered train journey is cancelled?

    If all or part of your registered train journey is cancelled, you will receive an e-mail from us about this. You can then register a new train journey.

  • How is it possible that the actual crowding on the train differs from the expected crowding?

    The crowd indicator shown gives an indication of how crowded the train can become. Naturally, we make every effort to provide a good estimate. However, the actual crowding may differ from our estimate, for example due to events that we were unable to predict such as faults, detours or emergencies.
