Abandoned Trains - Trains Magazine
The first locomotive in the video is a German-built Class 42 or 52 2-10-0 war Emergency locomotive, obviously in some railway collection (the semi-Vandy tender is the clue). Judging from the buffer, the locomotive to the left is probably pre-WWI. The second locomotive is a German Class 41 2-8-2, also in a museum; the locomotive in the background to the right is in far better shape.
The picture at 2:25 I'd bet was taken in Switzerland.
1:55 somewhere in Europe.
2:16 looks like a British Mk3 coach (the coupler!)
2:38 certainly look like former Soviet EMUs, but the unit in left foreground is not lettered in cyrillic, so I'd guess somewhere in the Baltic republics
3:10 a liquid-iron car somewhere in Europe (screw-link coupling)
4:54 looks like a Garratt, so maybe South Africa
6:45 is a Soviet EMU (class ER, built in Riga?)
7:25 is a lineup of former east German 1100 hp mixed-traffic diesels, probably inactive, but the loco in front is not long out of service.
Most of the rest are from the US and South America.
