DRG Locomotive Classification - Electric Locomotives

Electric Locomotives

The renumbering of electric locomotives followed in 1926/1927 and used a similar scheme as that employed for the steam locomotives, with a main class number and a serial number. They were distinguished from steam locomotives by a preceding letter E. The engines were arranged according to top speed and the number of driven and carrying axles.

• E 00–29: over 90 km/h
  • E 00: two driving axles
  • E 01–09: three driving axles
  • E 10–29: four driving axles
    • E 10–19: two carrying axles
    • E 20–29: more than two carrying axles
• E 30–59: over 65–90 km/h
  • E 30–39: three driving axles
  • E 40–59: four driving axles
    • E 40–49: two carrying axles
    • E 50–59: more than two carrying axles
• E 60–99: under 65 km/h
  • E 60–69: three driving axles
  • E 70–89: four driving axles
    • E 70–79: two carrying axles
    • E 80–89: more than two carrying axles
  • E 90–99: six or more driving axles

If the characteristics and design were otherwise the same, locomotives with a side-rod drive were given lower class numbers than those with individually driven axles.

As a result of technological advances the system was later further expanded and adapted. This resulted in the following scheme:

• E 01–99: Alternating current (AC) locomotives (16,7 Hz)
• E 101–199: Direct current (DC) locomotives
• E 201–299: AC locomotives (50 Hz)
• E 301–399: Dual frequency AC locomotives
• E 401–499: Quadruple system locomotives

• .01–.19: Top speed over 120 km/h
• .20–.59: Top speed of 90 km/h–120 km/h
• .60–.99: Top speed under 90 km/h
