High speed line rail substituting method for work train, involves unloading used rail sections on work train wagons, and disengaging train from track renewal site to substitute track with circulation capacity having normal commercial speed

摘要

#CMT# #/CMT# The method involves assembling elemental new rails (3) on long bars by sparkation-forging, and replacing the new rails by rail sections used by the bars. The bars are released by induction heating to a temperature between 25 to 32 degree centigrade, and are fixed immediately with a connection of the new rails, where the connection is done by an alumino-thermic soldering. The used rail sections are immediately unloaded on wagons (7) of a work train. The work train is disengaged from a track renewal site to substitute a track with a circulation capacity having normal commercial speed. #CMT#USE : #/CMT# Method for substituting a rail of a high speed line for a work train (claimed). #CMT#ADVANTAGE : #/CMT# The method permits to effectively substitute the rails on the high speed line without decreasing the commercial speed, when an operational phase alternates with an interception phase during execution period of track renewal site for substituting. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a track on which a work train moves along a particular direction. 1 : Rail tractor group 3 : Elemental new rails 6 : Substitution machine 7 : Wagon 8 : Chute.
