Railway Industry
The rail transport industry is one of the principal
areas of activity for CM4, engineering at all the different operational
levels in this sector.
Tool design and construction
o Construction of rail coach sub-assemblies, frames, roofs, coaches,
pivot cross sleepers....
o Welding process automatisation.
o Tools to aid mass assembly, levelling servosystems, boiler systems,
etc.
Equipment for testing departments.
o Extensometry test beds for rail transport coaches.
o Extensometry testing for measuring stress.
o Testing vibrations and own frequencies.
o Special weighing systems.
o Parking brake verification equipment.
o Equipment and testing of the pressurisation in high velocity coaches.
Design and line production of sub-assemblies
o Operating mechanisms of coupling traps.
o Access ramps for persons with reduced mobility.
o Axleboxes temperature detection system.
o Emergency ramps.
o Position control system for TV cameras used as rear-view mirrors.
o Infrared and radio frequency hand-held and remote controlled systems.
At CM4 we have the experience and resources to develop any type
of solution related with rail transport operation, from the technical
specification description of a component, to the design and construction
of the test beds to assess them.

| CM4 developed the roof welding system
of the Washington metro, which runs on an 82 kilometre long
network and is used by more than 3 million people. |
