Frankfort FRA to Eurail station

I may be wrong, but there are no Eurail stations. Eurail sells passes representing a consortium of European rail companies. If you have a Eurail pass, then look at the German rail site Bahn.de, you can find connections from FRA or if you need to head into the main station to catch a train. Also be aware of any mandatory reservations needed for a ticket, even with a pass, some trains may be off limits unless you purchase a reservation.

No, there are no "Eurail" stations.
There is a rail station AT the airport.
Somebody will come along shortly with more precise info, but it would be useful to peruse this site:

P.S.
Judging by your other posts you should really look at some guidebooks.

Paul is correct . You may have a Eurail pass, but there is no such thing as a Eurail train or station. You will use your pass on the various national trains. In most countries, travel on the high speed intercity trains will also require a seat reservation which you must buy in addition to the pass. This should be explained in your Eurail pass information.

While technically possible, 90 minutes is highly problematic. Just getting off the plane takes a while, then you have the walk to passport control and possibly have a long line if other international flights have landed just before you, then getting your bags from the luggage area if you have checked bags. Then walking to the train station, then finding your outbound train. There are all kinds of possible delays at each of these points. Personally I would add at least an extra hour. If the train leaves without you, then you would have to buy a new set of seat reservations (assuming any are still available- some train companies limit the number of seats available for Eurail pass holders).

If you are unfamiliar with the European rail systems, and how to use the Eurail pass, I highly recommend reading up on them on the Man in Seat 61 website.

Obvious question is if Paris is where you really want to go, why not fly there instead of Frankfurt? You may have a very good reason for this routing, but consider flying.

Taking a train from Frankfurt Hauptbahnhof to Paris only takes 3 hours, 49 Min. You will get to the city center of Paris faster going by train than by plane once you add in trains to get from CDG to Paris center.

I do not know if the train to Paris stops at the airport. Have you looked on the DB site or Oui for the TGV?

I had a look on the DB website and it looks as if the Frankfurt-Paris trains don't stop at the airport. Rather than go into Frankfurt HBf, the site-recommended itineraries recommend getting an ICE at the airport and changing to the Paris ICE at Karlsruhe, or going to Koeln and getting the Thalys.

1) There is no such thing as a Eurail station. Eurail is not a railway company, it is an agent in North America selling passes.

2) These passes are valid on trains operated by a number of companies, for example DB in Germany, SNCF in France, and dozens more.

3) Frankfurt am Main airport has a station, called "Frankfurt(M)Flughafen". It is in two parts a "Fernbahnhof" (long distance trains) and "Regionalbahnhof" (local trains). No taxi or bus needed, both are integrated into the terminals.

4) If you want to go from Frankfurt airport to Paris, go to the DB website: https://www.bahn.com/en/view/index.shtml
And enter "Frankfurt Flughafen" to Paris, with date and time and it will list al the trains needed.

5) 90 minutes is too short. You need to allow for immigration, possible late landing etc. 3 hours would be better

6) And finally, why are you flying into Frankfurt if you want to go to Paris?
You should be flying direct to Paris instead.

7) And have you checked a pass is the cheapest option? It often isn't.

Thanks folks. Good info. We have a couple of months, so have time to digest your great suggestions & plan accordingly. We do plan to use a 5 day pass to visit several cities, hence the thought to rail from & back to FRA rather than fly open jaw segments.
