Railway superstructures: Maintenance
Our experience
Alignment and levelling of tracks, tamping and profiling of the railbed and track stabilisation are vital operations for ensuring safe railway transport.
Especially with the advent of High Speed and High Capacity, line maintenance has become imperative for the railway line operators.
GCF S.p.A. has responded to this requirement for many years with impressive professional responsibility, with significant investments in training of qualified personnel as well as to expand the availability of the machines and technological equipment used in routine and special maintenance tasks.
Acquired experience and the accuracy of works carried out with continuity for lots regularly assigned in Italy by RFI (Italian railways) are the reason why the maintenance segment also took us abroad - where GCF has won important contracts in recent years, in railway and metro sectors alike.
Our competitive edge
- Flexible organisation of personnel.
- Technological equipment: computerised measuring systems on an absolute base.
- Efficiency: extensive fleet of machines, unique of its kind in Europe.
- Performance: quality and speed of execution.
Railbed tamping
Railbed tamping is performed using powerful machines that work using effective vibro-compression hammers capable of inserting crushed stone underneath sleepers.
GCF S.p.A. has about 30 tamping machines for lines and points (type Plasser 09/32/4S, Matisa B66U, Matisa B50D, Matisa B45D, etc.) that are also capable of performing track alignment and levelling thanks to efficient computerized technological equipment performing measurements on an absolute base and thereby ensure minimal error margins.
Profiling
A fleet of 18 Matisa R21 profiling machines is able to handle any type of final ballast outline with a yield of 15 km/h.
Final stabilisation
Five Plasser DGS62N stabilising machines ensure permanent stabilisation of renewed tracks with performances of up to 3 km/h ensuring maximum immediate and durable stability, thereby extending the life cycle of the initial geometry.
In this way, not only can lines be re-opened immediately to rail traffic but there is also an approximately 30% increase line seal, thereby reducing the need for maintenance.
