A ballistic protection arrangement for vehicles, in particular for rail vehicles chassis, with at least one first wheelset which has a first wheel, a second wheel and a wheelset shaft, wherein in order to provide advantageous construction conditions, a shell includes at least one first material layer, which includes a first fibre material, arranged around the wheelset shaft such that the wheelset shaft is advantageously protected from damage, for example, due to stone impacts at particularly high travelling speeds and at particularly low temperatures, where the first fibre material of the first material layer brings about high absorption of energy with the protection arrangement while, at the same time, having a low mass.

A Rail Drone can include: a payload interface, a drivetrain, and a rail platform 515. The Rail Drone can additionally or alternatively include any other suitable set of components. The Rail Drone can integrate a standardized payload interface and an autonomous electric road vehicle platform into a rolling stock architecture. The Rail Drone can be a stand-alone, payload-agnostic, motive element which can be independently or cooperatively capable of carrying heavy loads across long distances at various cruising speeds.

A railcar axle box includes an axle box main body accommodating a bearing supporting an axle. The axle box main body includes: an inner surface defining an accommodating space accommodating the bearing; a first side surface provided at an outer side of the inner surface and at one car width direction side of a car width direction center of the accommodating space; and a second side surface provided at an outer side of the inner surface and at the other car width direction side of the center. A shortest distance between the first side surface and the car width direction center of the accommodating space and a shortest distance between the second side surface and the center are equal to each other in a car width direction.

A covering system for wheelset shafts of rail vehicles includes a cover, a wheelset bearing unit, and a centering device. The wheelset bearing unit has an axis of rotation, a bearing housing with an end face facing towards the cover, and a wheelset bearing for the mounting of a wheelset shaft. The wheelset bearing has an end cap surrounded by the cover. The centering device is for aligning the cover in relation to the bearing housing. The centering device includes a groove on the end face.
