The locomotives Yeo , Exe , Taw and Lew of the narrow-gauge Lynton and Barnstaple Railway (L&B) in Devon were tank locomotives with a 1'C1 ' wheel arrangement. A fifth locomotive, a replica of the Lew named Lyd , was completed in 2010 by the Ffestiniog Railway . All locomotives are named after rivers in Devon. The series is commonly referred to as Manning Wardles after the manufacturer of the four historic machines .

history

The line was opened in 1898 with the Yeo , Exe and Taw locomotives built by Manning Wardle (a fourth machine, called Lyn , built by Baldwin followed a few months later ). Yeo and Taw had also been used during the last phase of construction.

In 1923 the Southern Railway (SR) took over the route, and the locomotives Yeo , Exe and Taw were given the numbers E 759 to E 761. In 1925, the SR procured another locomotive from Manning Wardle, which was called Lew and was numbered E 188. It differed only slightly from the first three, especially in a different shape of the driver's cab.

In 1935 the railway was closed due to inefficiency, and with the exception of Lew the locomotives were scrapped in December of that year.

The relatively new lev was used to dismantle the line and sold to Brazil in 1936 for use on a plantation. Their traces were lost in the turmoil of World War II, and it cannot be ruled out that the locomotive still exists. All previous attempts to clarify this question have, however, remained unsuccessful.

In the mid-1990s, the Ffestiniog Railway (FR) began a replica of the Lew in their workshops in Boston Lodge . Because it cannot be ruled out that the model still exists, the new name Lyd was chosen, which, like that of the models, comes from a river in Devon.

The Lyd differs from the four earlier locomotives in that it has a superheater and higher boiler pressure. In addition, the construction of the running axles was slightly modified because the FR and the Welsh Highland Railway (WHR) belonging to the FR , on which the machine is mainly intended to run, have narrower arc radii and higher gradients than the L&B. The driver's cab was designed with removable elements on the side walls so that the locomotive can pass through the Garnedd tunnel, which determines the clearance profile of the FR, whereby the external appearance deviates as little as possible from the original. The Lyd was originally fired with oil, in December 2011 it was converted to coal-fired, for which the locomotive was prepared from the start.

On August 5, 2010, the locomotive ran under its own steam for the first time. In September she gave guest appearances on other railways, first on the Launceston Steam Railway , then on the first restored section of the Lynton and Barnstaple Railway . For the planned reconstruction of another section of this line, replicas of the Yeo and Exe locomotives based on the Lyd model are planned, one of which, like this one, is to be built in Boston Lodge.

technology

The locomotives, which are relatively long and wide for this gauge, are built on an external panel frame. The drive and coupling rods are mounted on cranks. The running axles with their comparatively large wheels are stored in Bissel frames.

In contrast to the design prevailing in Great Britain at the time, the slides are located above the cylinder and outside the frame. They are operated via a joy control , a relatively rare design with a control rod articulated roughly in the middle of the connecting rod. The Lyd is one of only two operational Joy-controlled locomotives in the UK.

The standing kettle is much wider than the long kettle, and its upper edge is also above that of the long kettle. The boiler of the new locomotive is made using welding technology. The original locomotives, including the one built in 1925, did not yet have a superheater; the newly built Lyd is the only one equipped with one. The water tanks are arranged on both sides of the long boiler; the coal boxes are between the water boxes and the driver's cab.
