The Réseau Albert () was a set of railway lines in France from 1889–1955, part of the Chemins de fer départementaux de la Somme. There were four lines in the Réseau Albert system:- Albert - Doullens, Albert - Ham, Fricourt - Montdidier and Offoy - Ercheu. All lines were built to , metre gauge. The entire system extended to .
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 Réseau Albert system came under the control of the Somme Department.
Albert - Doullens line The long line between Albert and Doullens opened in three stages. Doullens - Beauval on 15 November 1888, Beauval - Beauquesne on 14 February 1889 and Beauquesne - Albert on 3 August 1891. The line crossed the high ground between the Ancre and Authie rivers. Its summit, at was between Acheux and Mailly-Maillet. The final section of line into Doullens was dual gauge, with the metre gauge rails laid inside the standard gauge rails of the Chemin de Fer du Nord's Amiens - Frévent à Gézaincourt line. An example of this method can be found on the Chemin de Fer de la Baie de Somme line.
During World War I, the line was in Allied hands. Before the Battle of the Somme in 1916, the line was truncated at Gézaincourt when the Standard gauge line of the Chemins de Fer du Nord was doubled. By October 1916, the line between Achuex-en-Amiénsois and Albert was disused. The section between Gézaincourt and Acheux-en-Amiénsois was used by the military, particularly for removing casualties from Acheux-en-Amiénsois to a casualty clearing station at Beauval. In preparation for the Battle of the Somme in 1916, branches were built from Martinsart to Aveluy, Thiepville Woods and Authuille to enable supplies of munitions to be brought up. Following the Battle of the Somme, the section of line between Acheux-en-Arménsois and Aveluy was converted to gauge. The first train on this section ran on 12 February 1917. In April 1917, it was decided that the line between Albert and Doullens should be restored to Metre gauge. The conversion work was slow due to a number of factors, including the lack of suitable materials, the refusal of the French to supply material and a difference in priorities between the British and the French. The British made the recovery of materials for use on standard gauge lines their priority, whilst the French wanted the completion and opening of the line to be the first priority. By July 1917, the Société Générale des Chemins de Fer Economiques (SE), of which the Réseau Albert formed part, was running two trains per day between Acheux-en-Arménsois and Gézaincourt. These took 20 to 30 minutes longer than they had pre-war. During the German spring offensive in 1918, the SE service ceased on 21 March. The Acheux-en-Arménsois to Gézaincourt line was the only part of the Réseau Albert to remaine in Allied hands. The line was subsequently prepared for demolition lest it should fall into enemy hands.
The line between Albert and Gézaincourt had been restored to service by 1922. It was subsequently extended to Doullens, probably when the standard gauge line was singled post-war. By 1938, following the introduction of railcars, a certain amount of rationalisation took place on all lines. Some stations and halts were downgrade to arrêts. All freight facilities were withdrawn from arrêts and those trains that did call we by request only. The line closed to passengers on 1 July 1949 and also to freight north of Acheux at the same time. The section from Albert to Acheux closed to freight on 31 December 1949.

Albert - Ham line The long line between Albert and Péronne opened on 1 April 1889. The line between Péronne and Ham opened on 24 October 1889. Its summit, at was near Montauban.
During the early part of World War I, the front line cut the line near Fricourt. The British did not use the line before the Battle of the Somme and it is believed the Germans did not use it either. The Allies had brought the line to Fricourt and beyond into use by October 1916. The British repaired the line from Albert south to Fricourt, and the French repaired the line north from Bray-sur-Somme, this section reopening on 14 July 1916. The line from Fricourt to Montauban and Trones Wood (between Monauban and Guillemont) was subsequently reopened. This section of line, from Albert to Trones Wood, was operated by the British. During 1917, the SE ran a single train each day between Bray-sur-Somme and Montdidier. At some point, the line between Maurepas and Péronne-Flamicourt was converted to Standard gauge by the British. A gauge line was laide alongside the standard gauge line, extending to Combles. In early 1918, the line between Péronne and Mons-en-Chausée, and also between Voyennes and Ham, was converted to gauge. It is not known whether or not the SE ran trains at this time. The line was captured by the Germans during the Spring Offensive. A number of bridges were destroyed. The line was demolished in October 1918.
The line had been repaired and reopened to traffic by 31 December 1922. In November 1938, the line between Offoy and Ercheu was closed to passengers. Services were restored during World War II. The entire line closed on 31 December 1949.

Fricourt - Montdidier line The long line between Rosières and Montdidier opened on 28 June 1889, and the line between Rosières and Fricourt opened on 26 October 1889. A summit, at was near Bray-sur-Somme. South of Bray, there were summits of near Hangestand near Fignières .
During the early part of World War I, prior to the Battle of the Somme, the line between Montdidier and Rosières-en-Santerre was used by the French Army. A third rail was added to make this section dual gauge with a gauge light railway. The line was disused north of Rosières-en-Santerre. A branch was built to serve the main headquarters of the French light railways in the Somme sector at Etelfray. The line was captured by the Germans during the Spring Offensive. A number of bridges were destroyed.
The line between Montdidier and Rosières-en-Santerre had been reopened by September 1921, with the line to Fricourt being reopened by 31 December. The entire line was closed to passengers, and to freight south of Froissy on 15 April 1948. The section to Froissy closed to freight on 31 December 1948.
