18 minutes from ARN to Stockholm Central, if you’ll pay for it
Arlanda Express South is the fast train from Terminals 2–4 and the southern side of Terminal 5 to Stockholm Central, with an 18 minute run time that business travellers rave about. Trains run every 10–15 minutes for most of the day, and several Reddit threads say it’s the only thing that reliably beats 30+ minute taxi or rideshare runs in traffic.
Standard adult one way at the station runs around $33–39 (about 320–360 SEK), which is why r/Stockholm users keep calling it “ridiculously expensive for such a short distance.” The same users point out frequent discount codes, advance deals, and weekend or two-for-one promos that can cut that price sharply if you buy online instead of tapping a card at the kiosk.
The “South” in Arlanda Express South refers to the access point near Terminals 2–4 and the southern end of Terminal 5, with the matching “North” access closer to the rest of T5; both lead to the same trains and platforms. Regulars say that if you land in T2 or T4, walking straight down to the Arlanda Express South entrance saves several minutes versus backtracking to the commuter rail station.
Figure 20–22 minutes door-to-door from terminal to platform at Stockholm Central once you include the walk and short dwell, even though the train itself runs about 18 minutes. Late evenings, Reddit users note that frequency drops below the standard 10–15 minute pattern, so missing a departure around midnight can erase most of the time edge over the cheaper SL commuter train, which also runs to Centralen.
Tickets work fine as mobile barcodes in the Arlanda Express app, and several frequent visitors say they always buy there in advance to skip station machines. Some FlyerTalk posters keep a running list of promo codes and report paying far under the 320–360 SEK walk-up rate on off-peak weekends and when booking more than a few days ahead.
Watch out for the generic “train” signs at Arlanda, which can feed you toward the SL commuter platforms instead of Arlanda Express South; a few confused travellers on r/Scandinavia mention walking back up one or two escalators after following the wrong arrows. Practical tip: before you leave the baggage hall in T2–4 or southern T5, open the airport map and head directly for “Arlanda Express South” by name, not just the generic train pictogram.
- Step 1: From Terminals 2, 3, or 4, follow signs to “Arlanda Express” and look specifically for the South entrance near the main arrivals hall.
- Step 2: In Terminal 5, walk toward the southern end of arrivals (by the 5A–5C gate cluster) before heading down to the Arlanda Express South escalators.
- Step 3: Buy a ticket in the Arlanda Express app or at the station machines; expect 320–360 SEK for a standard adult one way if you didn’t grab a promo.
- Step 4: Scan your mobile or paper ticket at the gates and head down to the platform; trains to Stockholm Central depart every 10–15 minutes for most of the day.
- Step 5: Ride 18 minutes to Stockholm Central (T-Centralen) and be ready to step off quickly; the dwell time there is only a couple of minutes.
- Step 6: Once at Stockholm Central, follow the “Metro/Tunnelbana” or taxi signs if you’re connecting onward into the city; allow 5–10 minutes to walk from the Arlanda Express platform to the metro concourse.
