Flannan Isles Lighthouse was designed by David Alan Stevenson, the 23-metre (75 ft) tower was constructed for the Northern Lighthouse Board (NLB) between 1895 and 1899 and is located near the highest point on Eilean Mòr. Construction was undertaken by George Lawson of Rutherglen at a cost of £6,914 inclusive of the building of the landing places, stairs, railway tracks etc. All of the materials used had to be hauled up the 45-metre (148 ft) cliffs directly from supply boats, no trivial task in the ever-churning Atlantic. A further £3,526 was spent on the shore station at Breasclete on the Isle of Lewis.[1] It was first lit on 7 December 1899. In 1925 it was one of the first Scottish lights to receive communications from the shore by wireless telegraphy.[2] On 28 September 1971, it was automated. A reinforced concrete helipad was constructed at the same time to enable maintenance visits in heavy weather. The light is produced by burning acetylene gas and has a range of 17 nautical miles; 20 miles (32 km). It is now monitored from the Butt of Lewis[3] and the shore station has been converted into flats.[4] Other than its relative isolation, it would be a relatively unremarkable light, were it not for the events which took place just over a year after it was commissioned.

In 1900, the keepers mysteriously disappeared.

The "railway tracks" referred to in the above may be thought an unusual item to pertain to a lighthouse. Their purpose was to facilitate the transport of provisions for the keepers and fuel for the light (paraffin, at that date; the light consumed twenty barrels a year) up the steep gradients from the landing places by means of a cable-hauled railway. This was powered by a small steam engine in a shed adjoining the lighthouse. A track descended from the lighthouse in a westerly direction and then curved round to the south. In the approximate centre of the island it forked by means of a set of hand-operated points humorously dubbed "Clapham Junction"; one branch continued in its curvature to head eastwards to the east landing place, on the south-east corner of the island, thus forming a half-circle, while the other, slightly shorter, branch curved back to the west to serve the west landing, situated in a small inlet on the island's south coast. The final approaches to the landing stages were extremely steep. The cable was guided round the curves by pulleys set between the rails, and a line of posts set outside the inner rail prevented it from going too far astray should it jump off the pulleys. The cargo was carried in a small four-wheeled bogie.[5]

The remains of the Flannan lighthouse railway as of 2012. This view is looking approximately west-south-west from the lighthouse. The site of "Clapham Junction" is just visible at left centre.

In the 1960s, the island's transport system was modernised. The railway was removed, leaving behind the concrete bed on which it had been laid to serve as a roadway for a "Gnat" - a three-wheeled, rubber-tyred cross-country vehicle powered by a 400cc four-stroke engine, built by Aimers McLean of Galashiels. This had a somewhat shorter working life than the railway, becoming redundant in its turn when the helipad was constructed.[6]
