Hello, This one - 3 kV DC. Voltage can be recognized by numbers - eg. EN 57 - 3 kV DC. Number in designation: Voltage: from 51 to 64 3 kV DC from 65 to 69 AC from 70 to 74 3 kV DC from 75 to 79 AC from 80 to 89 self-dependent carriage with engine from 90 to 93 0,8 kV DC from 94 to 99 other voltage
Interesting method for numbering units. 3000 VDC was the same as that used by my favorite US company. The Milwaukee Road. Now long gone. Boxcab E50
