AbstractIntroductionField InvestigationNumerical AnalysisField Settlement ObservationSite ApplicationEconomical Efficient AnalysisConclusionConflicts of InterestAcknowledgmentsThis paper proposes a new design of bridge-subgrade transition sections in high-speed railways,in attempt to avoid typical defects observed in such sections.Field observations show that two types of defects tend to occur at bridge-subgrade transition sections of high-speed railways the stiffness of the transition is usually too high so that tensile stress and even tensile cracks occur at the top surface of reserved trapezoid transition section and the compaction quality cannot be guaranteed within the firSee more on hindawiSome results are removed in response to a notice of local law requirement.For more information,please see here.12345NextBNSF RAILWAY COMPANY2.5 Track Recommended rail section is 115- lb.or greater.Hardwood ties shall be new 7 X 8 (No.4) or 7 X 9 (No.5),8 -6 long,placed on 21.5 centers with a 6 ballast section.Rail anchorage shall be provided at a minimum rate of 16 anchors per 39' panel.Continuous welded rail (CWR) shall be box-anchored every other tie.
Ballasted TrackNon-Ballasted TrackApplicationBallasted track is a type of traditional railway tracks.Ballasted track is commonly composed of steel rail,railroad tie,railway fasteners and ballast bed.Theoretically,ballasted track is the creation of railway track development.In 1865,the basic structure of the modern track structure was completed.Generally,laying ballast under the railway sleepersto reduce the stress on the ground.A layer of gravel was laid between groundSee more on railway-fastenersRailroad Equipment - CSXBi-level and tri-level rail cars are designed to transport pick-up trucks,minivans and sports utility vehicles.Each rail car has a maximum load capacity of 10 to 15 vehicles.Products like larger tractors,motor homes and military vehicles move on uni-level flat cars.Inside length 89',4 Inside width 8',7 Bi-Levels A-Deck height 7',4Barriers,Parapets,and Railings5/17/2017 Bridge Office mndot.gov/bridge 17 TL1 Work zones with low posted speeds,very low ADT,low speed local streets N/A TL2Work zones and local collector roads with favorable site conditions,small number of heavy vehicles,posted speeds are reduced LowBridge Railing Manual Bridge Railing for PedestriansA bridge with a speed 50 mph and above is considered a high-speed facility,and it must have a separator railing if pedestrians use it.See Appendix B,Acceptable Placement of Bridge Railing for Vehicular and Non-vehicular Traffic, for more information.
