On November 15, 2003, a special open day took place, commemorating the 40th anniversary of our locomotive having entered service. Aside from our locomotive, also former M61-017 (now working for MÁV PMLI Ltd.) was presented to the visitors.
The second half of the event was opened by Dr. József Csiba (director of the Mechanical Branch of MÁV Co.). Ervin Szórádi (former director of MÁV's Mechanical Dept.) presented a review of the beginnings of diesel traction in Hungary, and Olaf Janson (formerly employed at NOHAB) gave a historic overview of the NOHAB company.
The event was concluded by a video presentation of András Novák, giving a preview of the latest episode of NOHAB's Around the Millennium.
