I am looking to make a train booking from Brussels to Dusseldorf. Only direct train available is Thalys which is quite expensive, so i am looking to make 1 stop bookings via Cologne or Aachen.
But in all the options available the changeover from Cologne or Aachen is for just 15-16 minutes. Below is an example:
14:25 Bruxelles-Midi (Brussels)
16:15 Köln Hbf (Cologne Main station)
16 min transfer time
16:31 Köln Hbf (Cologne Main station)
17:01 Düsseldorf Hbf (Main station)
My worry is that if train from Brussels to cologne is slightly late then i will miss my train to Dusseldorf.
While booking train, i can see option of not making reservation and it says i need to search for my seat. I am not sure how this works.
Can someone please advice if its fine to make booking with connection time of just 15 minutes and if i miss my train from cologne then can i use same ticket in next train.
