Masanori HANSAKA, Naoto MIFUNE
In recent years the saving of labor for train maintenance is strongly
demanded, and train rubber hoses have to be used in service for longer time
and longer distance. In order to examine whether service life of train rubber
hose can be extended or not, the property tests of train rubber hoses were done.
As the results it has been revealed that the service of train rubber hose in
terms of the distance can be elongated to 750,000km, but in terms of time that
should not be elongated.
