Just released the the CN version of the Century 424 diesel to go with the previous releases of the BN, EL, PC, GBW, Wabash, and NW versions.
Nicely done. Good sounds. IMHO to me the only bother is the exhaust smoke when moving in notch 1, it looks like the puff puff of older KUJU units instead of a steady stream of smoke.
The prices are comparable to the past releases.

Particles is a story of a lot of emitters in the same spot and even of scripting on how these particles work synchronized with the engine.
