Okay, I came up with a plan.
First gonna join Nanjing in, but that needs a bridge, gonna be expensive. Also that place needs the large station. Beside passengers, gonna haul the wool there, and goods exchange can be done with Huainan.
Then connect Changzhou ASAP and further Shanghai for the ports. Those ports supply logs, and Changzhou has a lumber mill. Also a textile mill there and wool nearby, so can send goods right back to Shanghai.
Then there's Hangzhou to the south, with another lumber mill two ports maybe can supply two lumber mills, I'm not sure.
Finally I could also join in those resources NE from Changzhou, the farms, the cattle and sheep ranches.
But needs to act quick, industry tends to disappear if not supplied and the shit ain't transported away.
