Sirius again on the Czech network

After the unit 665.002 started testing under ETCS supervision on the Czech network at the beginning of June, the same EMU appeared again in September in Olomouc. Here, test runs were carried out by RegioJet on the sections Olomouc - Uničov and Olomouc - Štěpánov.

The aim was to cross the BTS station, because the GSM-R mobile terminal on the train registered under the BTS Olomouc must recognise during the train journey whether it should be re-registered to the BTS for the line in the direction of Uničov or under the BTS in the direction of Česká Třebová when leaving Olomouc.
