Trains/buses at Frankfurt airport and Eurail app question

I need your travel DATE and scheduled ARRIVAL TIME to access the schedule.

Don't use the Eurail Trip Planner.

Use the Deutsche Bahn website or app. They operate the train and will have the best information.

Russ, we arrive 8/31 at 8:45 am. Originally I saved an 11:24 train with no change of train, and those were available every 2 hours, but I don’t see those anymore.

If it is your plan to use a railpass day for the journey to Boppard, and you aren't in a huge rush to reach Boppard, you can avoid the buses altogether with a detour.

The railway problems that might be impacting your arrival day PROBABLY lie between the airport and the Rhine River town of Mainz, one of the stops on the direct route to Boppard. So with some extra time, you could do what I would probably do in this case...

No idea yet what time you plan to reach FRA, but probably morning... I'd board one of the 19 morning ICE trains leaving FRA for COLOGNE between 7 am and 12 noon. This trip takes 1 hour. I might break here to see the Cologne Cathedral (Germany's most visited landmark) or to have a meal at the station. Cologne station has baggage storage. Then catch a regional train to Boppard whenever you are ready. The direct regional trains to Boppard take 1.75 hours, and there is no railway construction going on on this route AFAIK. With your date/travel time, we could be more certain.

10:11, 10:22, 10:26, 10:48, 10:50, 11:10 departures for Cologne on 8/31. You'd probably make one of those.
Direct RB trains from Cologne > Boppard depart at :56 after every hour.

Yes, it's construction on the stretch between FRA and Mainz that is the problem.

Russ, we actually will be spending a couple of nights in Cologne after Boppard to visit Cologne and Aachen. Our plane is scheduled to land at 8:45, but I have no idea, of course, if it will be on time, nor how long it will take us to go through the entry system. I imagine we will want to take the shortest transit to Boppard. If that involves one of the bus replacements, I just don't know where we would find those.

General replacement bus service info:

I'm pretty sure all buses will be leaving from the Busbahnhof (bus station) at "The Squaire" - which is not far from the Fernbahnhof and Regionalbahnhof rail stations... see the map below and look for the bus symbol just above it. There should be signage that directs you there in Terminal 1.

My experience with replacement bus service has been BAD, but since you're leaving from FRA, I imagine there's a better chance that buses will actually be available, on time, and findable.

Thank you for the detailed information- very helpful! And I will keep in mind the travel through Cologne in case we don’t want to deal with the buses.

One last thing about the Eurail pass app: It is not necessary to have your exact schedule added to the trip. All you need to do is add something that triggers the activation of a travel day, and you are set.

The QR code that is generated does not contain train information. Your Eurail pass is a free travel pass, good for a day on any train covered by the pass. You are not generating tickets for specific trains.

Yes, you will need to take the SkyTrain from Terminal 3 to Terminal 1.

Every 2 hours the RE2 will leave from the airport regional station (track 3) and go to Boppard. At least that is what it says on www.rmv.de
Otherwise, you will need to go to the long distance station. Do use www.deutschebahn.de to find more connections.

WengenK, thank you for your reply. What you describe is different from what the Eurail site states, so I’ve been trying to save particular journeys:
“This is the part of your Pass that ticket inspectors need to see. Every travel day in your Pass has a different ticket, and each ticket shows all the journeys you add to your Pass for that travel day.
The ticket inspector will scan the barcode and check that the train you are on is listed on your ticket.”

The supreme advantage of the rail pass is its flexibility. Board any train you wish on any day at any time you wish, except when seat reservations are required or desired. It is not necessary to plan your travel days or specific journeys far in advance as long as you have input your journeys/tickets prior to boarding the train. From the Eurail site...

"You can create your tickets in advance or on the same day you’re travelling."

"Every 2 hours the RE2 will leave from the airport regional station (track 3) and go to Boppard."

Well, the DB site is quite clear that on Louise's travel date, the RE2 from FRA to Mainz is a REPLACEMENT BUS trip. In Mainz, Louise will need to transfer to the train; the RE2 train for Mainz > Boppard will be operational on this day, and Louise will be able to use it if in fact the RE2 Bus gets her to Mainz in time to make the connection. The 10:46 bus departure from FRA, for example, shows a transfer time of 10 minutes in Mainz. If this connection isn't made, she can catch the 12:02 RB train from Mainz to Boppard.

I’ve been studying all my options for this train trip, first checking DB app for best trips and then finding them on the Eurail planner. Interestingly, the Eurail planner came up with a better trip for this day that does not show up on the DB search. It has a 10:41 train from Frankfurt Airport to Frankfurt Main, 18 minutes to change, and then 11:09 direct regional train to Boppard. I checked DB site and both of these journeys show up separately but the DB app doesn’t connect these into one trip and doesn’t offer any choices that connect through Frankfurt Main. Is there any particular reason that I should know about? I don’t know if we will clear customs in time to catch this train but it certainly seems much better than catching the replacement bus for a longer journey.

Customs is literally walking through a door. I think you mean immigration?

You can take any train (S-8 or S-9) you want to the Frankfurt main train station, it does not have to be a specific train. That is probably your best bet. The train only takes 11 min. Then the 11:09 train to Boppard from platform 20. With your arrival around 08:45, you could be getting on that S-bahn by 09:45 or so. Gives you time to grab a coffee and snack at the main station, with little stress.

The train + train option to Boppard via Frankfurt (Main) is showing up at the DB site now.

The second train, the direct RE2 train from Frankfurt(Main) to Boppard, which normally stops at FRA airport on its way to Mainz and Boppard, is now using an alternative railway between Frankfurt and Mainz which takes you via Frankfurt-Hoechst and SADLY skips the airport entirely so that the construction on the normal route is avoided. This train runs only every two hours or so - 11:09, 13:09, etc. - but it's a good route for you.

The journey that you see at 10:41 from the airport's Regionalbahnhof station to Boppard via Frankfurt (Main) shows up for me as a journey of 1 hr. 54 minutes, as follows...

10:45 - 10:58 on the S-Bahn to Frankfurt (Main) +
11:09 - 12:39 on the RE2 from Frankfurt (Main) > Boppard

As Jo mentions, there's an 11 minute layover in Frankfurt. But as the DB schedule shows, 10 minutes of that time will be needed to get yourself from the lower-level arrival platform #102 to the main-level platform #20. This could obviously result in missing the RE2 to Boppard - and if you do miss it, the next journeys from Frankfurt (Main) to Boppard are 11:38- 13:38 (with 2 changes of train!) and 12:03-14:12 (with 1 change of train) - which turns your FRA airport > Boppard trip into a 3-hour obstacle course.

To keep your morning less crazy, take Jo's advice if there's any way you can do so - use an earlier S-Bahn train from the FRA Regionalbahnhof to Frankfurt (Main.) Will you make that 9:45 which Jo suggested? Possibly, if your flight isn't delayed and there are zero other hiccups. But that 9:45 is not your only option. There's also a 10:00, a 10:15, and a 10:30 S-Bahn to get into Frankfurt, any of which will provide you the time needed to switch platforms in Frankfurt. To find these trains, just make Frankfurt (Main) your "to" station from Frankfurt Regionalbahnhof.

Thank you for the replies. And yes, Emily, I did mean immigration. I haven't been through the new EES system so don't know how long the wait will be.

Thank you Ms. Jo and Russ for the excellent advice. That's what I think we'll aim for - catch train to Frankfurt main station to hopefully catch the 11:09 direct train to Boppard. If we don't make it for the 11:09, there is an 11:43 ICE train that transfers once in Koblenz. That might be the second best option. One last question, some of the connections from Frankfurt airport to Frankfurt Main are ICE and some S-Bahn. Is there a difference in walking time from these two different systems in order to make the RE train? If the timing becomes tight, would taking the ICE give me a shorter walking distance to transfer at Frankfurt Main? Obviously if I can get an early enough train, like 9:45, 10:00, or 10:15, it doesn't matter, but if I want to make that 11:09 train, which of the following is best, taking into account the time to walk to the second train?
10:30-10:43 S- Bahn
10:41 - 10: 51 ICE
Thank you for your help. I know that I'm getting very detailed, but I'd rather do the thinking now while I'm fresh and not when I'm fuzzy after long international flight.

No. You should go to the Regional station. You would have to walk to the long distance train station to take an ICE. It is farther away than the regional station. The ICE only use the long distance station. You need an S-bahn that goes from the Regional station, which is located right under terminal 1.
Look at the airport map and you will see. Just follow the signs leading to the regional station. Often hanging from the ceiling.

Thank you Ms. Jo. I’ll take the S-Bahn.

Skytrain leaves Terminal 1 next stop Terminal 2 which takes 2 minutes. Next stop terminal 3 which takes 6 minutes. Trains leave every 4 minutes. Same the other way. To get to the Skytrain from Terminal One head to the Sheraton Hotel. The Skytrain is steps from the Sheraton.

Interestingly, the Eurail planner came up with a better trip for this
day that does not show up on the DB search

The data in the Eurail Planner is often outdated, I would count on DB having it correct. And you shouldn't worry to much about having the correct trians in the planner. You add a trip to a day in order to activate it. It is actually not important that what you add to the trip exactly matches what you are doing. As long as it is more or less approximate.
Especially for regional travel the railways do not care a single bit about which exact train you are on.

I just want to thank all of your for your help. Despite the 1/2 hour late arrival of our plane, the 50 minute EES wait, the confusion (on our part) of finding the S-Bahn platform, the delays in the S-Bahn departure and mid-trip, we managed to get to the Frankfurt Main bahnhof and catch the direct regional train to Boppard with 2 minutes to spare. We would have been clueless without your help. Thank you!
