The Snowdon Mountain Railway from Betws-y-Coed Guide
The Snowdon Mountain Railway from Betws-y-Coed is one of the great days out in Eryri, and it has carried travellers to the summit of Yr Wyddfa since 1896. It remains the only public rack and pinion railway in the United Kingdom, so the journey itself is as much the draw as the view. At 3,560ft (1,085m), Yr Wyddfa is the highest peak in both Wales and England. Welsh legend holds that King Arthur defeated the giant Rhita Gawr in battle and buried him beneath the summit cairn. Some still say his knights sleep under the mountain today.
Since 1896: How the Railway Reaches the Summit
Sir Richard Moon, chairman of the London and North Western Railway, first proposed a railway up Yr Wyddfa in 1869. The Snowdon Mountain Tramroad and Hotels Company built the line in 1894, and trains began running in 1896. Five Swiss steam locomotives arrived to work the route, and three more joined them in the 1920s. The track climbs four and a half miles (7.5km) from Llanberis to the summit. It uses the Abt rack system, a toothed centre rail that grips a pinion wheel fitted under each carriage. Trains climb at around 5mph, so a return trip, including a 30 minute stop at the top, takes about two and a half hours.
Steam or Diesel: Choosing Your Ticket
The railway runs two kinds of service today. The heritage steam experience operates on selected dates and uses one of the original Swiss locomotives, pushing either a genuine 1896 style carriage or the newer Snowdon Lily, an accurate reconstruction built onto an original chassis. The traditional diesel service runs throughout the season and covers most departures. If you want the steam train up Yr Wyddfa rather than the diesel service, book directly through Snowdon Mountain Railway well before your visit, since steam seats sell out fastest. Each service also offers a shorter return to Clogwyn station, a useful option if cloud or high wind closes the summit.
Hafod Eryri and the View from the Top
At the summit, you can step into the Hafod Eryri visitor centre, which opened in 2009 and replaced an earlier building designed by Clough Williams-Ellis, the architect behind Portmeirion. It serves food and drink, sells souvenirs, and usually opens from May to late October. You get around 30 minutes to explore before the train heads back down, so it is worth planning what you want to see first. Weather on Yr Wyddfa changes fast, so pack a warm layer even in summer. On a clear day, you can see across Eryri National Park towards Anglesey and, on the best days, as far as Ireland.
Reaching the Snowdon Mountain Railway from Betws-y-Coed
Llanberis station sits around 16 miles from Betws-y-Coed, a drive of about 25 minutes along the A5 and A4086. If you would rather leave the car behind, the Snowdon Sherpa S1 bus runs a direct route between Betws-y-Coed and Llanberis, so you can enjoy your day trip from Betws-y-Coed to Llanberis without worrying about parking at the other end. Llanberis itself has plenty of parking near the station, though spaces fill quickly on sunny days. Arrive in good time, or book an early departure to beat the crowds.
