Unusual Occurrence Reports
A report indicating failure, withdrawal and any other technical
abnormality in locomotive /EMU observed on line is called Unusual
Occurrence Report (UOR). This should be made in each case recording
in full detail as to what has actually happened and what steps should
be taken in future to avoid recurrence.
While suitable proforma may be laid down by each Railway to
suite local requirements, the UORs should basically contain the
following details:
i) Report of Drivers/Motorman detailing all his observations,
together with remarks of TF (R) and Officers incharge of operation.
Observations made by Maintenance Organization i.e. Technical
Investigation section, Maintenance Foreman and AEE/DEE(RS)
UORs should be serially numbered for each calendar year to identify
the homing shed, class of loco and serial number of the occurrence for
the class of loco/EMU during the year
