New IR-2 have a lot of technology changes, compared to old IR. Initially I tried to load old IR save to continue playing it. But a lot of buildings vanished, primary - all smelters.

Steam powered factories are funny. It might look a little troublesome at start but worth playing.

It seems to me there is no flow/pressure loss in steam power pipes. So one can make them as long as he want without typical for liquid transport problems in classic pipes. Or maybe they just have good throughput and my little newbie factory not load them enough to cause noticeable loss of pressure in pipes.
