Several electric rail transportation systems currently use super capacitors for voltage enhancement, and improved recuperation of regenerative braking energy. In this paper, a comprehensive review of the various aspects related to super capacitors applied in electric rail systems, such as their design, sizing and modeling, has been presented.
While capacitors can be small for some applications, the capacitors found in rail guns are many cubic meters in size. Resistive heating: When an electric current passes through a conductor, it meets resistence in the conductive material -- in this case, the rails. The current excites the rail's molecules, causing them to heat.
Abstract: Supercapacitor (SC) is an energy storage technology that is rapidly developing, and being implemented in various industrial applications. Several electric rail transportation systems currently use super capacitors for voltage enhancement, and improved recuperation of regenerative braking energy.
Supercapacitors & Safety | ZTR
Capacitors are often employed to ramp or "smooth out" the response from excitation circuits. As an example, the locomotive crew will throttle up and down for train handling. Common excitation response circuits correlate a voltage for each throttle position, which is fed as a target to the excitation system. Step change voltage targets to ...

Power Supply rail capacitor bypassing/decoupling
When replacing opamps in some older equipment with newer opamps, I understand that it is good design practice to add decoupling passing capacitors right at the opamps'' power supply rail pins. What exactly does this do? Is it better to use ONE 100nF cap between the rails, or one from EACH rail to ground, or does it not make a difference either way?
