Does anyone know how to calculate the loop inductances of some DC overhead line railway system. i.e +ve supplied by overhead wires and -ve return via the rails.

page 3-44 Table 3.8 Magnetic Field and Self-inductance for simple configurations
e.g.
Ring
Rectangle with circular cross-section
Calculate:
1. Mutual inductance by the Biot-Savart (Ampere) equation
2. If two conductors are in the same plane, the Neumann Equation may be applied
3. For Self inductances: Reference:
