The constituent general meeting of the company was held on 1 February 1875 in Budapest, which Baron Viktor Erlanger did not attend.

He opened the founding general meeting by "transferring the rights granted to him (and not to Viktor) by the letter of authorizations to the limited liability company to be formed."

The BCmot from Celldömölk to Sopron from a 16-lane motor car and two of its sidecars crashed into the open-air mixed train in front of the entrance marker at Vönöck station.

The accident occurred due to the lack of braking of the train because the wagons were not connected to the main overhead line in Celldömölk.

On the morning of 15 November 1973, a serious accident also occurred, when the Cyclamen Express Train from Sopron via Győr to Budapest departed according to the schedule.

The driver of the express train to Budapest was right to believe that the track was free due to a poorly managed, so-called spacing signal.

In 2014, the railway company contracted 5 Siemens Desiro ML motor trains worth €32 million, which from 4 September 2016 on the Vienna-Sopron-Sopronkeresztúr (Deutschkreutz), Vienna-Pomogy (Pamhagen) section and from December on the Wulkaprodersdorf -Nezsider (Neusiedl) were set into service.

On the 10 of December 2017, rail passenger traffic at the border between Rajka in Hungary and Rusovce (Oroszvár) in Slovakia resumed.
