Traction curves and electric brakes? Not positive on the terms.

tensile pull curves/dynamic braking
Explanation:
See Eurodicautom (http://europa.eu.int/eurodicautom/Controller)
curva de tracción obtenido por descargas y cargas alternas:
"tensile pull curves obtained by loading and unloading the test-piece "

frenado eléctrico
"a braking system in which the traction motors, driven by the train,act as generators and feed into a rheostat"

Frenado eléctrico could either be:
rheostatic braking or dynamic braking

I have used dynamic braking in the past.

Also see:

"Dynamic braking (rheostatic braking) is a technology that enables the speed of a train to be controlled by cnverting the kinetic energy of train to electrical energy. The traction motors which normally convert the electrical power to motion, act as generators in this case. The electrical energy generated is fed to resistor bank which is forced cool by air circulation. This device is called Dynamic Braking Resistors(DBR)."

agree  xxxtnkw: I would have been more inclined to refer to them as 'traction curves' (?power drawn from the overhead line plotted against tractive effort?)

  -> Yes, I think you may be right. Traction = the motive power used for pulling (Oxford dictionary).
