built using the chassis of bogie wagons. These initial efforts at creating passenger stock proved unsatisfactory – they had a tendency to derail due to their very rigid construction. This caused a delay in opening, and a subsequent rapid redesign of the carriages. Early years The railway officially opened on 28 May 1971 but because of the need to redesign the carriage stock, the first public trains did not run until 19 July 1971. By the end of the first season, more than 30,000 passengers had been carried. In the winter of 1971 the railway was extended to its current terminus at Penllyn. For the beginning of the 1972 season, a second steam locomotive Red Damsel was returned to service with a new name: Elidir. The locomotive roster was expanded that year to include Maid Marian (now operating on the Bala Lake Railway) and an 0-4-0 tank locomotive built by Jung in Germany. Llanberis extension In June 2003 the railway was extended to the town of Llanberis, with a new station close to the start of the Snowdon Mountain Railway. The original terminus at Gilfach Ddu is now a through station serving both the National Slate Museum and the nearby Dolbadarn Castle. On the return journey from Pen Llyn, passengers may alight at Cei Llydan station, where a picnic site is available with views of the Snowdonian mountains above Llanberis Pass. Operations The railway uses three steam locomotives ("Elidir", "Dolbadarn" and "Thomas Bach") all of which ran on the internal gauge lines of the Dinorwic Quarry. There are also several diesel locomotives which are used for works trains and when the steam locomotives are unavailable for passenger trains. When the Quarry closed down in 1969 the lakeside section of the trackbed was utilised for the current Llanberis Lake Railway, originally running from the National Slate Museum at Gilfach Ddu to Pen Llyn. Gilfach Ddu was the main engineering workshop of the Dinorwic Quarry and provided repair facilities for all of the steam locomotives of the quarry system. Locomotives Current locomotives Former locomotives These are locomotives that ran on the Llanberis Lake Railway in the past, but have now moved to other locations. Locomotives formerly on site These are locomotives that were stored at the Llanberis Lake Railway in the past, that have now moved to other locations. They did not run on the LLR during their stay.
