One inverter unit per car, one inverter unit per truck and one inverter unit per axle are all available options. Not sure what the LIRR chose, but likely truck or car since the M7's are over 20 years old at this point.The rule of thumb for AC propulsion systems is that energy can be sent from anywhere to anywhere with little added complexity in the hardware. This means that much of the regen braking is provided by the vehicle's own HEP load, which is generally 600-100hp per train. It's not uncommon for modern electric locomotives and MUs to not be equipped with resistance braking. |
