Proposed is a train derailment and rollover preventing system to improve train safety. To prevent derailment and rollover of a train vehicle, the train vehicle can have a magnetic roller coupled to a magnet roller holder which can space apart the magnetic roller from the wheel. The wheel may be coupled to a wheel shaft which may be coupled to a train vehicle chassis and the magnetic roller holder may be coupled to the train vehicle chassis. The magnetic roller holder may include a shock adsorber positioned between the train vehicle chassis and the magnetic roller. The magnetic roller may include at least one of a permanent magnet or an electric magnet to supply a magnetic force. The magnetic force may be in a range of one hundred pounds pulling force to five thousand pounds pulling force. A train vehicle may be a locomotive or a train car in a train.

A support member may be connectable in a removable and adjustable manner to a track assembly. The support member may include an electrical connector, a contact, and a biasing member. The electrical connector may be adjustable to a first position and a second position. The contact may be connected to the electrical connector and configured to engage a conductor of said track assembly. The contact may be engageable with said conductor when the electrical connector is in the first position. The contact may not be engageable with said conductor when the electrical connector is in the second position. The biasing member may be configured to bias the contact into engagement with said conductor when the electrical connector is in the first position.

A vehicle control system is provided and may include a sensor that may measure an acceleration and a displacement of a vehicle during movement of the vehicle. The system may include one or more processors that can examine the acceleration and the displacement to identify an abnormal condition of the vehicle that includes an instability condition and/or a derailment condition of the vehicle. The processors may identify the instability condition responsive to the acceleration that is measured being no greater than an acceleration threshold and the displacement that is measured being no greater than a displacement threshold. The processors may identify the derailment condition responsive to the acceleration that is measured being greater than the acceleration threshold and the displacement that is measured being greater than the displacement threshold.
