7 The design parameters required for the detailed design derive from the technical specifications and from the sector legislation governing the subject and they define the constructional tolerances. The fundamental parameters used are geometrical, kinematic, architectural and vehicle-related. Subsequently, on the basis of the regulations and design parameters acquired, it is possible to define in detail the elements that normally constitute the executive design phase, e.g. route planimetries, typological planimetries, sections, altimetric profiles, finishing materials, bills of quantities etc. 7

10 SLAB TRACK STS SYSTEM Slab Track System is an innovative system made of prefabricated, prestressed, reinforced concrete slabs which are laid on a foundation thanks to the insertion of a special bedding slab injected in situ. Strengths: makes it possible to travel at high speeds, reducing noise and vibration levels guarantees shorter manufacturing and laying times allows road vehicles and pedestrians to transit on the railway line offers an expert, full time technical support service, from design through to laying considerably reduces maintenance costs, which are limited to routine cleaning of the surfaces and overhauling of the rails and the fasteners The STS system does not require traditional maintenance operations regarding: tamping of the ballast levelling cleaning renewal replacement of the ballast The system envisages a service life of the platforms, the bedding slab and the (optional), anti-vibration, elastomeric bed of at least 50 years. The superstructure maintenance plan simply consists of: the ten-year overhaul of the fasteners and weldings the replacement of the rails after 20 years The STS system is, therefore, a real turning point in terms of economic savings. 10

11 RAILWAY SLEEPERS AND SWITCH BEARERS SLEEPERS SWITCH BEARERS IPA division is the leading manufacturer in Italy of switch bearers. Since 1985, it has been designing and manufac-turing rail switch bearers of the types in use in the railway network and in compliance with the technical specifications and standards in force. The production process adopted, fruit of studies and experience gained over decades of production, is structured using prestressing technology with post-tensioned smooth wires anchored at the end by means of steel plates. The manufacturing plant is equipped with single moulds with 4 sections, fixed, around which the various processing phases are carried out: demoulding, preparation, casting, curing and demoulding once more. Once the components have completed the curing cycle and have been removed from the moulds, they proceed to the preparation, tensioning and finishing department which complete the production cycle. The materials, design and manufacturing technologies used by the IPA division for the production of prestressed concrete sleepers with smooth pre-tensioned and post-tensioned wires that are anchored at the ends, are subjected to the controls of the Quality Assurance department in order to check the compliance of the sleeper geometry with supply specifications and with the new European standards. 11

12 BRIDGES Within the Italian railway sector the innovation process has involved IPA division in the study and production of advanced solutions for railway bridges, through a series of technologically advanced solutions which respond perfectly and in a balanced manner, not only to mobility requirements, but also to the need to safeguard the environment. And indeed in terms of quality of transport and considerable reduction in noise and vibration pollution, IPA division p.r.c. bridges make it possible to almost totally reduce the vibrations and noise deriving from railway traffic without neglecting safety, while dedicating due attention to aesthetic aspects and to efforts not to create a nuisance. The use of prefabricated components and IPA division systems for high speed bridges and viaducts, road bridges, railway and underground lines, level crossings and road crossings make it possible to achieve: a considerable reduction in the dimensions and weight of the works (thanks to prestressing) a reduction in manufacturing times (replacement of a single span bridge overnight, avoiding excessive inconvenience due to the interruption of traffic) substantial savings on maintenance costs while obtaining a structure with high technological content great flexibility and adaptability to any use, from the replacement of ballast to the removal of the pre-existing decking with a reduction in thicknesses and an increase in height clearance versatility of use total reliability 12

13 NOISE BARRIERS IPA division has developed a cutting edge solution to efficiently resolve problems related to noise pollution. Special lightweight concrete panels are coupled with membrane devices based on the principle of sound wave interference, thereby avoiding the installation of unsightly barriers that would be seen by passengers and residents living along the railway route. The main elements of this system are: multiple-layer acoustic panel with an external layer made of concrete with expanded clay. Its characteristic surface roughness helps create a series of small intercommunicating sound chambers with high noiseabsorption capacities the Calmzone element which boosts the performance of the multi-layer panel thanks to its invisible screen It produces a refracted sound wave that overlays (destructive interference) the one emanated by the noise source, causing a significant reduction of railway noise, in the region of around 16 Db. The characteristics of the materials used to make IPA division s noise barriers give the system an almost unlimited service life, low maintenance cost and high selfcleaning properties. 13
