1. A transportation system having a control apparatus for controlling the operation of the transportation system, wherein the control apparatus comprises:
- a storage circuit provided with a non-volatile memory for storing an operational state of the transportation system; and
a power supply backup circuit which comprises a capacitive energy storage, wherein the power supply backup circuit maintains power supplied from the capacitive energy storage to the storage circuit for a given length of time in connection with an operational anomaly in power supplied to the control apparatus, and upon detection of the operational anomaly in power supplied to the control apparatus, the non-volatile memory starts storing the operational state of the transportation system in the non-volatile memory until a movement of the transportation system stops.
