Sorry, only just seen this query. It's South Africa, Rovos Rail, Cape Gauge (3' 6"). The station is Rovos' depot at Capital Park, Pretoria. The loco is Class 25NC no 3533, which I have myself fired in the past. There's some wheel slip in the video, quite possibly demanded by the film company, as drivers tend to avoid wheel slip, which can damage both wheels and track. Firemen also hate it as it can blow holes in the fire.
