Construction
The first lines built, linking Caen with the coast used 15 kg/m rails. The loading gauge allowed a width of 1.88 metres (6 ft 2 in) and height of 2.80 metres (9 ft 2 in). Gradients were to be no steeper than 30mm/m (1 in 33). Trains were to be restricted to 20 kilometres per hour (12 mph) with a maximum length of 60 metres (200 ft). Later lines were built with rails of 18 or 20 kg/m and the earlier lines were upgraded in the 1930s. Many of the lines were laid alongside roads or canals.

Famous quotes containing the word construction:
“When the leaders choose to make themselves bidders at an auction of popularity, their talents, in the construction of the state, will be of no service. They will become flatterers instead of legislators; the instruments, not the guides, of the people.”
—Edmund Burke (1729–1797)
“There’s no art
To find the mind’s construction in the face:
He was a gentleman on whom I built
An absolute trust.”
—William Shakespeare (1564–1616)
“There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.”
—John Dewey (1859–1952)
