This one got my attention because it is in retro color scheme. It was on regular line but runs also sometimes on H4 line here, so it is museum piece.
this era of trams are such a vibe, unfortunately it's like the one era we didn't really have here in Melbourne :(
we kept using the wooden w classes for many decades until we suddenly got the modern z class (derived from pcc/Gothenburg trams the engineers saw iirc)
In Brno (where it is taken) there are about 20 types and subtypes of trams in use.
When I looked it up we have still in use about 100 of these T3 that are regularly running. They don't get replaced much, just modernized.
This one is restored to 80/90's configuration and is registered as museum piece but still runs pretty regularly on 10 line.
Trams are just so simple that you don't need to replace them that often.
That's so cool that they run museum pieces in regular service, we have steam trains and legacy EMUs that run on our network but it's only ever for events, never revenue service.
