The locos seem to be Slovakian class 770, the Slovakian version of the CME3 built by CKD in the former Czechoslovakia. The CME3 is a 6-axle heavy shunter/road locomotive and was/is ubiquitous is most countries in Eastern Europe. A total of 8200 units were built between 1963 and 1994. The USSR version has been modeled by Roco.

Stumbled across a YouTube video that turned out to be the loading of a S-300 anti-aiorcraft missile system onto a train bound for Ukraine.
While more modern, European, and timely than much of what we model, it was a interesting mix of equipment, including RR rolling stock and some very decrepit looking motive power that may have only been the yard switchers lining things up. Some of this might be available through Trident, but being mostly Soviet origin, it would make for an interesting challenge.
