The Snowdon Mountain Railway is unlike any other railway in Britain. Since 1896 it has carried passengers from Llanberis to the summit of Yr Wyddfa — a climb of nearly 1,000 metres in under 8 kilometres, using a rack-and-pinion system that locks the train to a toothed rail between the running rails to prevent it sliding back down the mountain. It remains the only public rack railway in the United Kingdom.
The journey is extraordinary. In less than an hour the train rises from the slate rooftops of Llanberis through pasture, then open mountain, then bare rock, to emerge at Hafod Eryri — the summit visitor centre — with views that extend, on clear days, to Ireland, the Isle of Man, and across the whole of Wales. Even in cloud the journey through the changing mountain landscape has its own drama.

History
The railway opened on 6 April 1896 — and immediately suffered a disaster. On opening day a locomotive ran away downhill and was derailed, killing a passenger. The railway closed for a year while an inquiry was held and modifications made. It reopened in 1897 and has operated without serious incident since. Victorian and Edwardian visitors who had previously faced a strenuous mountain walk could now reach the summit in relative comfort — a development that transformed Snowdon's visitor numbers and played a significant role in establishing the mountain's reputation.
Booking
Advance booking is strongly recommended, particularly in summer. The railway operates to the summit only when weather conditions are suitable — services may terminate at Clogwyn station (approximately two-thirds of the way up) in poor visibility or high winds. Check the railway's website for timetables, prices and real-time service information before travelling.
The Summit Experience
Hafod Eryri, the summit visitor centre, opened in 2009 and replaced a much-criticised earlier building. It provides a café, toilets, and interpretation panels about the mountain's natural and cultural history. The terrace offers the classic panoramic view on clear days. In summer the summit can be crowded — arriving on an early service or staying until late afternoon generally means fewer visitors.
