A traction substation (605-01-06) is a substation whose main function is to supply a traction system (railways, trams and/or trolleybuses). They are often located near a railway.
Power line coming from local power grid aren't mandatory around since such substation can improve power repartition from a train tracks feeder line.

name=Sous-station de Ventabren
|25kV traction substation with 2 auto-transformers. No power lines feed this substation except the contact line 25kV feeder going along train tracks.|
operator=DB Energie GmbH
|Traction substation with two 26.5 MW Motor–generator-sets. Power is taken from the 110 kV 50 Hz 3-phase-grid and converter to 110 kV 16,7 Hz single-phase current, which is transmitted to other substation, but also transformed to 15 kV power to be fed in the overhead lines. Energy flow can be from the national grid to the railway grid or vice-versa.|
name=Woburn rail traction substation
|Inddor traction substation which converts 11,000-volt 50Hz AC power from local grid with static rectifiers to 1500 V DC.|
