An auxiliary act is understood in railway traffic to be an act which, in the event of a fault or special operational conditions , is carried out instead of or in addition to a normal act in order to maintain operations and to compensate for a reduced technical level of safety.

What is meant is a manual, safety-relevant intervention in the security system that requires a record or the creation of auxiliary locks and notes. As a rule, these are actions by railway employees in the event of technical faults or construction states in which technical safety functions are wholly or partially bypassed or switched off.

The alternative actions also includes a support operation . In modern interlockings , an auxiliary action is usually documented automatically (e.g. on a printer , a data cassette or a specially installed hard disk ). With older interlockings, auxiliary controls are switched on in an electromechanical counter. The dispatcher then has to make an entry in the evidence of the counters , in which the new meter reading, the process with justification for the necessity and the signature of the person who undertakes the intervention is recorded.

Any auxiliary service is only permitted after operational substitute measures (other auxiliary actions) have been carried out. For this, the regulations of the driving service regulations must be observed. They are to be documented. This makes it possible to prove that an auxiliary act was carried out and what the reasons were.
