> A rather amusing situation was encountered with another train set that refused to work on November 21, 2022, despite not being in service at the time. The computer reported a compressor failure, although the mechanics determined that there was nothing wrong with the compressor. Unfortunately, the train still did not raise its pantographs. The analysis of the computer code revealed a condition enforcing the failure, which read as follows:
> if the day is greater than or equal to 21, and
> if the month is greater than or equal to 11, and
> if the day is greater than or equal to 21, and
> if the month is greater than or equal to 11, and
> if the year is greater than or equal to 2021
> then report a compressor failure.
