I understand that sounds funny
. But realy, we still operate with telex machines and we actualy still use Lorenz LO 133. In my department we have mechanicer who still can repair it and I'm repairing another kind of telex, Sagem TX 20, it's advanced machine comparing to Lorenz, with lot of electronic inside (of course, comparing to time when it was constructed for first time-about 1980). We will stop this telex network this year.
I have information that Croatian Railways also have telex network operating, I know that simply bcoz we are in touch by phone with their tecnicians and our network is also conected to them.
With best regards.
