How easy is it to take a train to Darmstatd from the Frankfort airport?

Forget the train. There is a direct bus from Frankfurt Airport to Darmstadt city center. It takes just under 45 minutes and they run about every 30 minutes.

Airliner Direct Bus

Correct spelling of the towns might be important: Darmstadt and Frankfurt

Frank is correct. The bus is as fast as the train and you don't have to make a transfer.

Do not pass on visiting the Hessisches Landesmuseum. It has a fantastic display of fossils and minerals, and very good art and historical displays.

Unlike Frankfort (Kentucky), Frankfurt has nothing to do with a fort, which in German would be a Burg or a Festung.
A Furt is a ford (no, not the car), a shallow spot on a river, a good place to cross.

Stadt in German means a city. The a is pronounced as in the English word at.

I do realize that I misspelled Frankfurt and Darmstadt in my original post. I’ll blame it on the 40 degree below zero temperature and promise not to do it again. Thanks for the advice about the bus service. Very much appreciated.

@ Frank II: The PDF file shows fares by "Preisstufe" for PS 4 -7, but I think FRA to Darmstadt is a PS 4 fare. Why do they show PS 5-7 if they are not relevant?

It looks like the airline bus has a surcharge of 3,80€ on top of the 6,90€ RMV fare, for 10,70€, total. Alternatively, taking the S-Bahn to the Hbf and RE60 to Darmstadt takes 51 minutes, but save 3,80, and you get to ride in a trains instead of a bus.

You have one change.. Depending on the time, take the S8 to either the Frankfurt Hbf or to Mainz Bischofsheim.

At the Hbf, get off in the underground station, come up the escalator to the ground level platforms and find the track for the RE60. You'll have 21 minutes to do that.

Or, at Bischofsheim, you'll have a 12 minute cross-platform change to RB75.

Oh, I see you are flying delta, which arrives at Terminal 2. It looks like about a third of a mile walk to the Airline bus stop. To take the S-Bahns, you'll take either the shuttle bus or the Skyline from T2 to the Regional Bahnhof at T1.

@miarnold:
Sorry, I wasn't trying to pick on you. Those mistakes are ubiquitous amongst Americans, mistaking Frankfurt (2 of them in Germany) for Frankfort (Ky), and mispronouncing Stadt.

Particularly, so many Americans pronounce Stadt, with the 'a' sounding like ah. but that's the pronunciation of Staat, the German word for a state, as in a country or a nation. And the German word for what we might call a state, like Bavaria, is Land. Again the 'a' is pronounced like in 'at' and the 'd' is devoiced to a 't' sound.

While this doesn't address your transportation query , don't miss this place while you are in Darmstadt https://en.wikipedia.org/wiki/Darmstadt_Artists%27_Colony

Lee, I don't look for the cheapest way to do things. I look for the easiest. If easy costs me a few Euros more, so what. In the scope of things, and comparing a few Euros to what I'm paying for the entire trip, I'll pay a few more for convenience, ease and comfort.

If you take the bus you don't have to walk to Terminal 2. Use the Skyliner tram.
