Train Question

[Modelcar]

....Just a basic answer would be to say the electric traction motors that propel the engine are switched by the engineer to become generators and that current is then sent to giant grids to absorb the current and load the traction motors and causing them to act as brakes slowing the train on the downgrade. Massive fans remove the heat from the grids caused from absorbing the current. [8D]

Hi Everybody:

I'm new here, and I have a question about locomotives. What is dynamic braking, and why do dynamic brakes slow the train down?

Thanks!
