Mike, we were in the Slovenia Railway Museum in Ljubljana in July this year. 06-018 is currently under repair in the roundhouse.

The museum is amazing, but is not publicised, even on the station! We had to ask some locals for directions. The chap in charge actually unlocked the museum for us! It is well worth a visit, and definitely should be widely publicised, I am sure the tour operators could take coach parties there. But it is owned by SZ and is not a priority for them.
