Here is a picture I took of a Rovos Rail steam engine.
The loco is still fully operational and is a South African Railways Class 19D - built originally in 1938 in Berlin by Borsig Lokomotiv Werke.
The condition that you see it in - i.e. spotless (bear in mind it is a working locomotive) - is normal for Rovos Rail, who run some of the worlds most luxurious trains.
A real class operation - have a look here:

And there are lots of virtual tours so you can get a real feel - here is a couple but there are many more.

A small anecdote - last time I was there, a train was about to leave and I was talking to a couple of stewardesses (each individual compartment more or less has its own steward/stewardess). They were sitting in the floor by the carriage entrance (the floors are all carpeted).
I asked them why they were sitting there, and they explained they had finished the carriage prep for on-boarding the passengers and were now waiting for them. But, they did not now want to walk around anymore, as the last thing they had done was sweep the deep pile carpets in one direction - and if they walked around this would leave footprints!
