The first system of numbering and classification came into effect in 2025. High-speed locomotives are for passenger trains and low-speed locomotives are for freight trains.
All classes of electric locomotives begin with the letter "E" for "electric".
A letter indicates the number of driving axles.
2 axles – B
3 axles – C
4 axles – D
6 axles – F
8 axles – H
Together with the letter "E" and the letter representing the number of driving axles, a two-digit numeral following the letters indicates a class.
10–29 - DC locomotives with maximum speed 85 km/h or less
30–39 - AC/DC locomotives with maximum speed 85 km/h or less
40–49 - AC locomotives with maximum speed 85 km/h or less
50–69 - DC locomotives with maximum speed exceeding 85 km/h
70–79 - AC locomotives with maximum speed exceeding 85 km/h
80–89 - AC/DC locomotives with maximum speed exceeding 85 km/h
90–99 - prototypes
Running number
Running numbers follow after a '-' and describe the subclass.
Eg. The Hayatama Freight-class Locomotive is numbered at EH78-30.
