Does the regenerative braking feature on the newer trains mean that the train is actually saving energy by running local instead of express?The answer has to be no. You can't get energy out of nowhere - that would breach the laws of thermodynamics. Necessarily, the energy used by accelerating away from each additional station stop would be more than the energy gained by slowing down regeneratively at each stop. |
