Synopsis:

Modern Railway Tracks on SNCF French railways in 1960s.
The building techniques of a modern railway, including switches and laying rails. A technical, engineering based film.
Making railways. Factory where railway tracks are being manufactured. A hydraulic press carries out the process of sparking. Looks like lengths of track are being welded together. Lots of sparks flying. A man operates or oversees the machine. A forge presses on the weld joins. Hot forge process. Outside the factory, rails are buffed by machine. Rails are fed into a welding machine. The machine operator stands at the controls. Welds are trimmed within the machine. A man grounds down welds with a hand held grinder, to create a smooth finish.
Rail proceeds along the assembly line where it is cooled with a water spray. A man uses a press and measures the rail for trimming. The next stage is cold grinding.
Lengths of track bar are loaded onto a train. The train then moves the track to its installation point. Overhead view of the tracks proceeding along a curving railway line through a forest.
Rail installation process. Lengths of track are pulled off the train and guided into position by men holding long poles. Aluminothermic welding carried out trackside.
In an office setting, two seated men watch another man drawing on a blackboard. An electric train heads towards the camera. Close up of sleepers and track beneath the train. Back in the office a man draws an anti-creeping device on the blackboard, used to stop rails from shifting. The three men discuss the drawings before they are rubbed off. Views of trains heading towards the camera and low angle views of the tracks. The three men from earlier stand around a model on a table top. They discuss a dampening device which helps the rails cope with vibration. A piece of rubber cushioning in close up. Diagrams are shown that illustrate how the connection with the rail works. A view along a railway track from a low angle with a bridge in the middle distance. Close up view of the fastenings attaching the rail to the sleeper. A hand lays out the parts that make up the fittings, sleeper screws, steel blade, hook, steel plaque and the rail is lifted to show the rubber mat underneath. Three men sit around a single desk deep in discussion over a brochure they leaf through. View of tracks where sleepers are made of concrete, instead of wood. Screws dipped in mastic are then turned into the concrete sleeper. The similar system of fittings and fastenings is then demonstrated. Cut through diagram is shown of a concrete sleeper and how the screws fit. Length of track where expansion gaps have been made. Graph showing the rate of increase of track installation between 1949 and 1961. Fast moving view of the track from behind a train.
