Ukrainian Railways are operating even close to the front lines (where physically possible due to destruction). Outside of those the service is pretty much as usual — both sleepers and daytime intercity. Sometimes there are delays if the electric grid gets hit by the missiles, but then they just attach a diesel locomotive to pull the train instead.

International connections work too. My mother recently came to visit it us here. She took an intercity from Przemyśl, Poland on the way here and then a sleeper to Wien, Austria on the way back. Both arrived more or less on time.
