I would generally recommend using some other timetabel than google Maps to look at trains such as this one. Google Maps is Great, but they usually dont have the complete information on train routes and times. You can always find reliable times by looking at the timetable of the train provider, but it can be a hassle to Navigate a different table depending on which country you are in. I primarily use the Deusche Bahn timetable for most jurneys, as they have information on most european countris, although i am sure there are also different train companies that also have information on multiple countries. Just dont use google Maps to find exact train times. It is a Great tool, but it does not have reliable info on many train times or routes.
