C.E.M.E.S. S.p.a. specializes in the construction of contact lines for railway electric traction. Over the years we have contributed to build, adapt and renew the contact lines for over 2,000 km. Among the R.F.I. qualifications we obtained, there is one related to the interventions on electric traction and electric power distribution. The work carried out in the field allowed us to be qualified to design and carry out electric traction works for unlimited amounts.
