Railway maintenance activities, as part of a field playing an important role in nations that are dealing with new issues before others, are gaining the attention of other infrastructure operators as well. We thus see as an important mission that we have to take Itsuki Koshiishi Maintenance Issues for Railway Facilities empirical development of maintenance practices • Maintenance engineering focus of last 40 years - Under heavy axle load operations, rail represents highest maintenance and replacement cost area for track structure - Under high speed passenger operations; track geometry represents highest maintenance cost area • Safety is a major area of Periodic Maintenance The Regular Cleaning actions above should be used when required to maintain optimum performance and appearance. Coral FR can stop up to 95% of all dirt and moisture entering a rail vehicle - the frequency of Periodic Maintenance will depend on the efficiency of the Regular Cleaning actions in relation to Maintenance is "an activity aiming to maintain something in good working order, prevent operational disturbance and/or uphold a given technical standard" (RailNetEurope 2017). The two main maintenance types are preventive maintenance and corrective maintenance. In the former, measures are taken after an item's failure, while the latter is The railway infrastructure asset needs an innovative, integrated and proactive solution for its interoperability requirements for the improvements in safety and security, reliability and maintainability. High operative and maintenance costs are barrier for improved financial performance of railway operation (ERRAC, 2007). Therefore, solutions for . 3. What should be considered while acquiring Right of Way? 1.Depths of cuts and fills. 2.Slopes. 3.Side ditches. 4.Erosive action of wind and water, etc. 5.Future double tracking6.Price of land, as the land value increases after construction of railway facility.Increasing or acquiring R/W afterwards could be more costly. Railway maintenance is defined as the process of preserving a condition or the state of being preserved, along the track or related to vehicles, but there are actually different approach to mantain a railway asset or service: 1. Corrective Railway Maintenance Rail Maintenance A regular maintenance program is required to maintain the appearance and function of your S.R.Smith rails. Cleaning The maintenance program includes thorough cleaning of all rail components. Insufficient cleaning leads to a buildup of chlorides and other aggressive chemicals that exceed the corrosion resistance of the stainless - Circular No. 20/2013/TT-BGTVT dated 2013/8/16 on management and maintenance of railway structure. - Circular No. 15/2009/TT-BGTVT on response to railway accidents and incidents. - General technical regulations concerning urban railway operation and maintenance (Draft) - Basic design of urban railways 2, 2A and 3 lines Track © 2007, American Railway Engineering and Maintenance-of-Way Association 5-1-2 AREMA Manual for Railway Engineering LIST OF FIGURES (CONT) Figure Description Page In this paper preventive maintenance works consists of routine(spot) maintenance activities, viz. small repairs that do not take much time and are done frequently (e.g. revision of track and switch, inspection of rail, switch, signalling system, switch lubrication) and projects, viz. larger works that take much time to be done and are carried ou In this paper preventive maintenance wo
