Contact loss and wear of contact wire on overlap sections are larger than those on normal earea
of Shinkansen. It is important to modify overlap structures to one what can reduce contact loss
and wear of contact wire. We measured height and wear of contact wire and acceleration produced
on vibrating pantographs of a testing train at overlap sections of JYOETU Shinkansen to investigate
the relationship between height and wear or acceleration. Furthermore we calculated current collecting
characteristic of overlap sections by simulation. According to the results we obtained, we can keep
the wear ratio of cuntact wire at appropriate value by maintaining a constant height of the wire.
