From the start railroads in France, by 1830, rotundas are built to shelter the material(equipment). They had a wooden skeleton, were small dimensions(size) (54 metres in diameters) and could put away only 24 locomotives. The rotunda of Chambéry, built between 1906 and 1910 by the railroad company PLM (PARIS-LYON-MÉDITERRANÉE) and the "new Company(Society) of foundries and engineering workshops of Fourchambault", distinguishes itself from the latter(these last) by its imposing dimensions(size) which allow him(her) to shelter up to 72 locomotives thanks to his(her) 36 radiant(shining) ways. With her 108 metres in diameters and her steel structure, she is the last one of this type in France. The central part(party) in the shape of dome rests(bases) on eighteen metallic pillars connected(bound) between them by an uninterrupted beam. Of each of these pillars the half bows(arcs) leave which support(bear) the slate roof. The roofing is itself topped with a lantern. The dome is surrounded with a ring 26,5 metres in diameters serving as garage for locomotives. The radiant(shining) farms which support(bear) the coverage(cover) lean indoors on the same metallic pillars as the dome and outside on the polygonal wall of stone surrounding wall(speaker) constructed of size of Villebois (career(quarry) near(about) Ambérieu, in Ain). The importance of the diameter of the building imposes not to use a classic steel structure anymore. As a result, the engineers of the PLM dealt with works of Gustave Eiffel. They opted for the use of an articulated(uttered) steel structure. Today, the rotunda, and its annexed workshop(studio), is still used by Technicentre Rhône-Alpes, establishment which assures(insures) maintenance and repair of materials(equipments) TER and of Freight.
