What is Double-End Feeding

Chapter 19
Handbook of Research on Emerging Innovations in Rail Transportation Engineering
It is a traction network electrical scheme where two adjacent electrical sections are connected, so the two substations at the same time feed any train in whichever section. This scheme produce lower voltage drops that the single-end feeding scheme but the voltage between the overhead conductors and the rails in the two sections must be in phase.

Abstract
This chapter describes the different electric railway power supply systems and their main characteristics from the point of view of the power flow modeling and simulation. It considers the DC traction systems and also the AC ones, explaining the different elements embedded in the network and proposing steady state electrical models of each element. The basic methods for modeling the train behavior in terms of demanded/regenerated power are also detailed. Finally, the procedures to simulate the trains motion into the electrical network and how their motion and power demand affect to the electrical variables will be unraveled, explaining how to merge all the models in a system of equations.
