my config for steel mill :)

@MG83 i try to make realistic rails. Thats why i builded so many stable tracks before steel mill. That's why i builded additional side track to allow loco u-turning. If i find that rail traffic will be too small i will increase manpower at steel mill to 2000 and expand it with some custom warehouses.

yeah looks well but toally unnecessary for the steel mill. mill will never have production capacity to fill 3x train at same time. :) so there is not much line required front of it.
