Mr. Behr was encouraged to construct a monorail in Kerry, between Listowel, a country town famous for its butter, and Ballybunion, a seaside resort of increasing popularity. The line, opened on the 28th of February 1888, has worked most satisfactorily ever since, without injury to a single employé or passenger. On each side of the trestles, two feet below the apex, run two guide-rails, against which press small wheels attached to the carriages to prevent undue oscillation and “tipping” round curves. At the three stations there are, instead of points, turn-tables or switches on to which the train runs for transference to sidings. Road traffic crosses the rail on drawbridges, which are very easily worked, and which automatically set signals against the train. The bridges are in two portions and act on the principle of the Tower Bridge, each half falling from a perpendicular position towards the centre, where the ends rest on the rail, specially strengthened at that spot to carry the extra weight. The locomotive is a twin affair; has two boilers, two funnels, two fireboxes; can draw 240 tons on the level at fifteen miles an hour, and when running light travels a mile in two minutes. The carriages, 18 feet long and carrying twelve passengers on each side, are divided longitudinally into two parts. Trucks too are used, mainly for the transport of sand--of which each carries three tons--from Ballybunion to Listowel: and in the centre of each train is a queer-looking vehicle serving as a bridge for any one who may wish to cross from one side of the rail to the other. Several lines on the pattern of the Ballybunion-Listowel have been erected in different countries. Mr. Behr was not satisfied with his first success, however, and determined to develop the monorail in the direction of fast travelling, which he thought would be most easily attained on a trestle-track. In 1893 he startled engineers by proposing a Lightning-Express service, to transport passengers at a velocity of 120 miles an hour. But the project seemed too ideal to tempt money from the pockets of financiers, and Mr. Behr soon saw that if a high-speed railway after his own heart were constructed it must be at his own expense. He had sufficient faith in his scheme to spend £40,000 on an experimental track at the Brussels Exhibition of 1897. The exhibition was in two parts, connected by an electric railway, the one at the capital, the other at Tervueren, seven miles away. Mr. Behr built his line at Tervueren.
