What does TCIR mean in UNCLASSIFIED

TCIR stands for Train Control Incident Report. It is a report that documents an incident involving a malfunctioning railway train or other rolling stock in service. This report includes the details of the incident, the cause of the incident, and any corrective action taken by a railway company or other relevant organization.

The preparation of a TCIR involves gathering information such as detailed descriptions of the incident, photographic evidence, and interviews with operators and witnesses in order to accurately assess what happened and its cause. This report can then be used to identify potential improvements that may need to be made in order to prevent similar incidents from occurring in the future.

A TCIR can be used to document incidents such as sudden acceleration or deceleration of a train, incorrect signals being given, power interruptions, derailments, collisions between trains or with other objects, and any other type of issue related to railway safety or operations.

The train operator or an official appointed by the rail administration must submit this report immediately after an incident has occurred. If necessary, additional reports can also be filed at later dates if additional information becomes available about it.

A copy of each TCIR must be kept on record for at least five years by both the railway company and national authorities such as local governments and transport ministries who are responsible for implementing safety regulations in their region. This record helps ensure that records are kept up-to-date so that any issues can be properly addressed even after they have occurred.

A TCIR must include key details about the incident such as time and location where it occurred, who was involved (ie; operator/passenger/other witnesses), equipment involved (including track conditions) and most importantly what corrective action has been taken since then (if applicable). It should also provide additional data such as weather/lighting conditions during time of occurrence.

Some countries may make their historical data on past incidents accessible online while others may not — this will vary depending on each government's policies concerning access to public information. In either case it is best practice for organizations within largest countries like India, China and USA keep their own databases with all relevant information regarding past incidents which could then be easily accessed upon request.

All major malfunctions involving Rolling Stock require documenting through filing this report regardless whether it was caused by human error or malfunctioning equipment e.g.; unexpected speed change due to Degradation/Faulty parts etc., thus requiring action for further investigation into causes & possible solutions ASAP.
