Chemin de fer de Boulogne à Bonningues


The Chemin de Fer de Boulogne à Bonningues was a gauge railway from Boulogne to Bonningues-lès-Ardres, Pas-de-Calais, France, where it had a connection with the Chemin de Fer d'Anvin à Calais. It opened in 1900 and closed in 1948.

Background

In France, the building of railways was controlled by the Government. This avoided the duplication of routes that was seen in the United Kingdom and meant that the large cities and towns were connected. The citizens of the smaller towns and villages also wanted railways to be built to connect them to the network. The departments were given authority to oversee the construction of these minor lines, some of which were built to standard gauge and others were built to metre gauge or less.
The Loi Migneret of 12 July 1865 established that railways in France were to be classified as of Intérêt Général or Intérêt Local. The former were deemed to be of sufficient importance that they could be partly charged to the state. The latter were charged to the department.

History

In 1883, a proposal was put forward for a railway from Le Portel to Bonningues-lès-Ardres, in the Pas-de-Calais department. It was decided at an early stage that the line would have to go through Saint-Martin-Boulogne, a village from Boulogne which lies at an elevation of. This presented a problem as a direct line would be too steep for steam trains. Two options were considered, an route from the Gare de Boulogne-Ville northwards via Terlincthun and a route southwards via the Val Saint-Martin. Consideration was given to the line east of Licques running to Tournehem-sur-la-Hem instead of Bonningues-lès-Ardres.
In 1890, permission was given to the Compagnie des Chemins de Fer Économiques du Nord to build three metre gauge railways in Pas-de-Calais. Two were to run from Boulogne; one to Le Portel and the other to Bonningues-lès-Ardres. The third line was to run from Frévent to Lens. The two lines from Boulogne were run separately, with the Boulogne–Le Portel line operated as an electric tramway.
The long line between Saint-Martin-Boulogne and Bonningues-lès-Ardres opened on 22 April 1900. In part, it ran through what is now the Parc naturel régional des Caps et Marais d'Opale. In 1901, the Tramways Électriques de Boulogne-sur-Mer extended their tram line to Saint-Martin-Boulogne. This was to affect the viability of the section of line between Gare de Boulogne-Ville and Saint-Martin-Boulogne. The CF de BB was extended to the Gare de Boulogne-Ville on 12 May 1902, giving a total length of. Boulogne and Bonningues-lès-Ardres are from each other in a direct line. By November 1902, the CF de BB was asking the department for permission to reduce the number of trains between Gare de Boulogne-Ville and Saint-Martin-Boulogne. It is likely that the request was granted. In 1909, the CF de BB carried 112,946 passengers.
In 1911, a proposal was made to run a branch line from the Boulevard Daunou to Boulogne's waste incineration plant, on the banks of the Liane. The branch was used to transport waste from the incineration plant to the town dump on Val Saint-Martin.
The CF de BB remained behind Allied lines during World War I. Boulogne was evacuated in 1914 but was later one of the major ports used by the Allies to import materiel. The line saw little use by the military for much of the war. In November 1917, the British Army laid an long siding at La Waroquarie to serve a camp at Ostrohove. Following arguments re the provision of safety measures at the siding, from March 1918 a six-wagon train was run each night from Boulogne to La Waroquarie to bring in supplies.
Following the war, the CF de BB was suffering due to a lack of maintenance of its locomotives and stock during wartime, leading to poor timekeeping. Although services had been improved since 1917, when only one train a day ran the whole length of the line, there were still complaints. A 1919 request to reinstate a late train from Licques to Bonningues-lès-Ardres was refused on cost grounds. In the 1920s, extra trains were laid on from Boulogne to the Hippodrome de lInquéterie, a horse racing track between Blanc-Pignon and Souverain-Moulin. French bureaucracy required that the CF de BB had to apply for permission to run these extra trains for each and every race meeting. A new locomotive was ordered in 1922 at a cost of ₣108,000. It was in service by 1925. Another locomotive was ordered in 1924. In 1929, permission was given for part of the passenger service to be operated by buses.
On 31 December 1935, the department bought the concession to operated the CF de BB from the CEN. The line was closed completely between Val Saint-Martin and Colembert, and to passengers between Colembert and Bonningues-lès-Ardres. Freight services on the remaining section of the CF de BB were to be worked by the Chemin de Fer d'Anvin à Calais. The Boulogne end of the line was given to the Boulogne Town Council in January 1936, for an initial three-year period. It was reclassified as an industrial tramway. What locomotives operated in Boulogne post-1935 is not known, but they were not those of the CF de BB. In 1938, the railway between Val Saint-Martin and Colembert was officially declassified. In July 1939, six locomotives, 23 carriages, 32 goods wagons and five lorries were offered for sale by the department. Also offered for sale were the tools and effects from Saint-Martin-Boulogne depôt, and all moveable effects from the stations at Belle-Houllefort, La Capelle and Saint-Martin-Boulogne.
World War II broke out on 3 September 1939. On 7 May 1940, it was reported to the department that all tools and effects from the depôt at Saint-Martin-Boulogne had disappeared apart from the largest items. All six locomotives were in the depôt, but had been stripped of valuable metals such as copper. The wagons had been broken up and all wood removed. Only one lorry remained. The job of compiling a full inventory hampered by the fact that the depôt was occupied by a motorised unit of the French Army. It was reported that what was left was in a severely worn condition only fit for scrap and that there had been much theft and pillaging. Boulogne fell into German hands on 24 May 1940. The Pas-de-Calais department became a zone of special control, administered by the Oberkommando der Wehrmacht in Brussels, Belgium. Along the coast was the "red zone". It was said that French law did not apply in this zone. Under the terms of the armistice, France was to hand over its railways to the Germans undamaged and was to work with the German authorities to restore them to serviceable condition.
In September 1942, the Marine Verpflugungamt decreed that the line between Boulogne and Colombert was to be brought back into use. It was reported that the section between the Gare de Boulogne-Ville and Le Portel was being operated by TEB. Boulogne Town Council were also using the line to Val Saint-Martin. Seven sections of railway, totaling had been lifted and some sections of track at level crossings had been tarmaced over. About a quarter of the sleepers would have to be replaced. No rolling stock from the CF de BB was available. It would cost ₣2.65 million to return the railway to use. The line reopened in November 1942 with two trains a day available for conscripted workers. The railway ceased to be used for the transport of waste at Boulogne in April 1944, due to its stock being requisitioned by the Germans. The track serving the incineration plant was taken up. In May 1943, the MVA required two trains to run daily between Lumbres and Boulogne. From 7 June, ten trains a day were to run between Lumbres and Saint-Martin-Boulogne with supplies for the Kriegsmarine. These trains were to be operated by the Compagnie Générale des Voies Ferrées d'Intérêt Local. Boulogne was bombed by the Allies on 17 September 1944 and liberated on 22 September. The Gare de Boulougne-Ville and all bridges over the Liane had been destroyed, as was the bridge over the Route de Paris. The latter was not rebuilt.
In 1945, the mayors of the communes served by the CF de BB held a meeting, requesting the reopening of the line between Saint-Martin-Boulogne and Colembert. They pointed out that it had already been refurbished and returned to use by the Germans. Although there was support from the Conseil-Général, the line had been damaged between Saint-Martin-Boulogne and Blanc-Pignon. Further inspection revealed that the Germans had only made the line fit for short-term use. It was stated in 1946 that bus services then being provided were adequate. VFIL stated that it was costing ₣9 million per year to run the freight service from Colembert to Bonningues-lès-Ardres. The line closed in 1948.

Accidents and incidents

There were many minor accidents, mostly involving horse-drawn vehicles at level crossings. A few were of a more serious nature.
From the Quay Chanzy at Boulogne-Ville, the railway ran in the street, across the Pont de la Lampe over the Liane. One side of this bridge had to be strengthened to take the weight of the trains, trams of the Tramways Électrique du Boulogne ran on the other side, which did not need to be strengthened. The railway then ran along the Rue Pierre Daunou, under the Boulogne–Calais railway and along the Rue de Brecquerecque to La Madeleine Halte. Leaving the road, the railway began a climb to Saint-Martin-Boulogne, crossing the Route de Paris by means of an overbridge with a span of and a clearance of over the road. The line continued around the Val Saint-Martin through Ostrohove and La Waroquerie to Saint-Martin-Boulogne, at an elevation of. Saint-Martin-Boulogne was the headquarters of the CF de BB, with a locomotive depôt and carriage sheds located near the station. The line then descended through Blanc-Pignon to Le Wast-Alincthun before climbing again through Colembert to a summit at between Longueville and Surques. The line descended to Licques ( before climbing to Bonningues-lès Ardres, where there was a junction with the Chemin de Fer d'Anvin à Calais.
Rails were Vignole rails, except between Boulogne and La Madelaine, where tramway rails of were used. Minimum curve radius was. Maximum gradient was 30mm/m for near Ostrohove. The next steepest gradient was 22mm/m for between Le Wast-Alicthun and Colembert. Apart from the bridge over the Route de Paris, the only other significant bridge was that over the Hem near Audenfort.

Stations

Station had a two-storey building, some of which had a single storey wing that handled freight traffic. Halts had a single storey building. Arrêts may have been provided with shelters, although some had no facilities. For further details of stations marked, refer to the article on that system.

Passenger stock

For the opening of the line in 1900, 22 four-wheeled carriages were bought. These had end platforms. Three were first class, with seats for six passengers and room for eight more to stand. They also doubled as fourgons. The other nineteen carriages were second class, eighteen seated and fourteen standing. By 1914, a composite carriage had been added to the fleet.

Freight stock

For the opening of the line in 1900, 52 wagons were bought. These were a mixture of flat wagons, open wagons and vans. Following World War I, 28 further ex-British Army wagons were acquired. When the line closed, 4 flat wagons, 15 open wagons and 13 vans were offered for sale.
