Ensuring the power supply of the data recorder

In the collision, the fuses of the locomotive's batteries broke down, causing the data recorder to fail. Independent power supply is not required for data recorders in the TSI, which means that important information may be missed during accidents if power is cut out.

An independent power supply is required for new rolling stock being type approved that guarantees the operation of the recorder for a minimum of 30 minutes after power has been cut off.
