£2–£5 gets you from Rhoose station to T1 in 5–10 minutes
The 905 Rail Link is a short shuttle bus between Rhoose Cardiff International station and Cardiff Airport T1, aimed at travellers using the Cardiff–Bridgend rail line. The ride itself takes about 5–10 minutes and typically costs in the $2–5 range if you pay separately instead of bundling it into a rail ticket.
Services run roughly every 30–60 minutes, with the 905 scheduled around specific Transport for Wales trains rather than as a standalone 24/7 bus line. In practice that means it works best in daytime and early evening when the Cardiff Central–Rhoose trains are running regularly, but gaps appear if a train is cancelled or retimed.
The smart move is to buy a through ticket to "Cardiff Airport" instead of to "Rhoose" from stations like Cardiff Central, Bridgend, or beyond, since that through fare normally includes the 905 bus so you don’t have to pay the driver the extra $2–5. Rail forum regulars repeat this tip constantly because it keeps the whole rail-plus-bus combo on a single ticket.
Door-to-door from Cardiff Central, plan on 35–45 minutes including the train to Rhoose Cardiff International and the 5–10 minute 905 hop to the terminal. One RailUK poster sums it up as “train to Rhoose, then the 905 bus to the terminal,” while a Reddit commenter notes the shuttle is “meant to meet the train” and usually appears a few minutes after passengers step onto the small station platform.
Step-by-step: using the 905 Rail Link
- 1. From Cardiff Central or Bridgend, buy a rail ticket marked "Cardiff Airport" so the 905 bus is included in the fare.
- 2. Board the Transport for Wales train towards Rhoose Cardiff International; the ride from Cardiff Central typically takes around 30 minutes.
- 3. Get off at Rhoose Cardiff International station and follow the signs for the airport shuttle; the station is small with just a couple of platforms.
- 4. Wait at the 905 stop outside the station; the bus is timed to the train, but if you miss it you may face a 30-minute wait for the next connection.
- 5. Ride the 905 Rail Link for 5–10 minutes to Cardiff Airport T1 and get dropped near the main terminal entrance.
What regulars do and what to watch out for
Regulars check live train times before leaving Cardiff Central so they land at Rhoose only 5–10 minutes before the 905 is due, rather than sitting on an exposed platform with limited facilities. If your train is delayed and the timings don’t match, you can end up waiting close to 30 minutes for the next bus, with very little shelter at the station.
Signage at Rhoose for the 905 can be patchy, especially after dark, and locals note that the bus doesn’t always pull right up to the tiny station entrance. Give yourself a few extra minutes at night to find the stop, and build a 15-minute buffer into your airport arrival time if you’re checking bags at T1 for an evening departure.
