 Technical Reference: 103 Series
Introduced in December 2007, the 103 Series was Eishindo's
first trainset. A set comprises four cars: two powered units in the middle, and two non-powered units on the ends, which
contain directional lights. The 103s have some quality control issues, with reliability varying considerably between units.
The mechanism consists of a chassis part that press-fits into a shell. The chassis holds the trucks and motor.
The shell holds the gearbox in place over the one powered truck. Springs pass current from both trucks up to two power strips
embedded in the underside of the shell roof.
Drawings are not to scale.
