I just received an email advising me: "Mashinky is now available in Early Access on Steam"
Mashinky's Steam Store page (http://store.steampowered.com/app/598960/Mashinky/) states: "Mashinky is a transport strategy game about trains. The goal is to create your own transport empire on a procedurally generated map. It’s a unique blend of realistic graphics combined with an isometric construction mode and board game-like rules."

I rarely spring for an Early Access title, especially one selling for full price, but I need something to scratch my itch for a railroad game--at least until Railway Empire (http://store.steampowered.com/app/503940/Railway_Empire/) is released next year.
