Herb: my secret is out, that Fireman is waving a guitar, not a shovel.
The location is Wolsztyn yard & depot on the Zbasyn-Lezsno line, I know it well !.
Not all the locos are from the Wolsztyn Depot. I don't recognise some of the locos, looks like they rounded up stuff from all over the place.
Poland has a bit of a mixture of steam classes left over from various previous political regimes; ex-Soviet (Russian), ex-German etc.
I do not know if their is anything on YouTube but here in the UK there was a run with a load of diesel shunters (switchers). All 8 coupled. Not as impressive as that steam show, but still interesting. Will now search YT to see if there is anything.
One day I might finish something................. find out if I do at my own paid for site (under construction) http://www.picsntech.co.uk
