Yes, the railroad track between Přerov and Břeclav in the Czech Republic was electrified over a multi-year period in the early 1980s, with electrification works carried out roughly between 1981 and 1985. The line carries both 3 kV DC and 25 kV 50 Hz AC traction systems, with the changeover point near Hulín. cs.wikipedia.org<ref>{{cite web|title=cs.wikipedia.org|url=https://cs.wikipedia.org/wiki/%C5%BDelezni%C4%8Dn%C3%AD_tra%C5%A5_P%C5%99erov%E2%80%93B%C5%99eclav|publisher=cs.wikipedia.org|access-date=2026-01-25}}</ref>

Not being some random person online who might remember, here’s what is actually documented about the traction-system changeover point on the Přerov–Břeclav railway:

Electrification work happened in 1981–1985, and the line uses two different electrification systems: 3 kV DC and 25 kV 50 Hz AC. Wikipedia<ref>{{cite web|title=Wikipedia|url=https://cs.wikipedia.org/wiki/%C5%BDelezni%C4%8Dn%C3%AD_tra%C5%A5_P%C5%99erov%E2%80%93B%C5%99eclav|publisher=cs.wikipedia.org|access-date=2026-01-25}}</ref>

Current (as of late 2025) position of the changeover point
The point where the 3 kV DC system switches to 25 kV AC used to be in Nedakonice. That was the operational arrangement for decades. Wikipedia<ref>{{cite web|title=Wikipedia|url=https://cs.wikipedia.org/wiki/%C5%BDelezni%C4%8Dn%C3%AD_tra%C5%A5_P%C5%99erov%E2%80%93B%C5%99eclav|publisher=cs.wikipedia.org|access-date=2026-01-25}}</ref>

However, a recent adjustment moved the contact point northwards out of Nedakonice toward Hulín/Říkovice (technically onto the Hulín side of Říkovice station). The new contact point has been in operation since 15 July 2022. Wikipedia<ref>{{cite web|title=Wikipedia|url=https://cs.wikipedia.org/wiki/%C5%BDelezni%C4%8Dn%C3%AD_tra%C5%A5_P%C5%99erov%E2%80%93B%C5%99eclav|publisher=cs.wikipedia.org|access-date=2026-01-25}}</ref>

So to be clear, I’m talking about the actual, current infrastructure setup:
* Up to mid-2022 the DC/AC boundary was at Nedakonice. Wikipedia<ref>{{cite web|title=Wikipedia|url=https://cs.wikipedia.org/wiki/%C5%BDelezni%C4%8Dn%C3%AD_tra%C5%A5_P%C5%99erov%E2%80%93B%C5%99eclav|publisher=cs.wikipedia.org|access-date=2026-01-25}}</ref>
* Since 15 July 2022 it’s been at the Hulín/Říkovice side of the line (still between Přerov and Břeclav). Wikipedia<ref>{{cite web|title=Wikipedia|url=https://cs.wikipedia.org/wiki/%C5%BDelezni%C4%8Dn%C3%AD_tra%C5%A5_P%C5%99erov%E2%80%93B%C5%99eclav|publisher=cs.wikipedia.org|access-date=2026-01-25}}</ref>

That’s not some historical footnote but the present operating situation on the track.
