1. An electric rail vehicle comprising:
a bogie frame defining a longitudinal axis and a lateral axis perpendicular to the longitudinal axis, the bogie frame having a stiffness mismatch between the lateral and longitudinal axes;
a set of bumpers mounted to the bogie frame, the set of bumpers comprising an abutment surface at a maximal extent of the electric rail vehicle along the longitudinal axis;
a payload interface configured to mount a cargo payload to the electric rail vehicle;
a bolster bowl rotatably mounting the payload interface to the bogie frame;
a plurality of suspension elements coupling the payload interface and the bogie frame which are symmetrically distributed relative to a midsagittal plane of the bogie frame;
an electric powertrain mounted to the bogie frame and comprising a plurality of rail wheels;
a battery electrically coupled to the electric powertrain;
a set of sensors mounted to the bogie frame, the set of sensors comprising: a bumper feedback sensor and a GPS sensor; and
a vehicle controller mechanically coupled to the bogie frame and configured to autonomously control the electric powertrain based on measurements from the set of sensors.
