@Ilia.Obuhov.52 The BLS Re 465 is the "Swiss army knife" of all locos. The non refit version is able to communicate with old BLS and SBB locos. The refit version is able to communicate with Bombardier TRAXX and Siemens Vectrons but lost the necessary electronics for communication to older locos. Until the refit program started in 2019 this image was normal on the Lötschberg transit route.
