Here's a second shot, Picture 3 in my own collection, showing one of the ballast hoppers behind the Class 741's.

I've never gotten a photo of a CD Class 741 diesel before, as they're a bit rare. These two are actually operated by Viamont, which is a construction contractor and TOC, and as such are pulling a ballast train. Their TOC operations are mostly in regional services, using Class 810 railbuses, but I haven't seen any of them yet. Getting back to these locomotives, the 741 Class are relatively new by Czech standards, having only been introduced since 2000 by CZ LOKO, a rebuilder who make them out of old Class 740 hood units originally built by CKD in the 1970's and 1980's. In addition to the lowered hood, both long and short, as you can see here, these locomotives have been regeared for 90Km/h service. Power is still 883kW (1184 horsepower), however.

This train had another small locomotive that looked even smaller than 700162-1, but it wasn't. #703713-8 is a Class 703 diesel, which weighs 24 metric tons, 2 more than a Class 700.

There seems to be at least some MOW equipment based in Modrany, in addition to the spine cars that I saw there for containers (From where I don't know. I'm assuming the intermodel facility where they're loaded and unloaded is elsewhere.). The locomotives used for the Modrany MOW trains are exceptionally tiny, this one being a Class 700 diesel that only weighs 22 metric tons.

I'm not sure of what the lead unit on this work train is, as it's purpose is far from clear, with no obvious built-in tools. Is it a track geometry car? That might explain the coach, which would make a decent mobile computer lab.
