there are also these two modernisations which annoyingly enough aren't referred by modertrans as Moderus Beta, but they still somewhat resemble the other modernisations (and use Moderus Beta numbering scheme anyway), first one is an abomination that once was a Konstal 114Na (second pic is what it looked like before the modernisation), and third photo is a Tatra RT6N1 that also got modernised by Modertrans, but didn't get as butchered as the 114Na
