Yeah, definitely. Some sort of modifier reducing production efficiency whilst the distrubance of propping up some new factories takes place.
Maybe have some sort of provincial division or breakdown of state industry - maybe at least just visual eye candy more so than anything actually significant? Infrastructure then, should definately have a direct impact upon the workings of industry. As I take industry to be more than "several factories", and proper industry needs proper infrastructure and networks.
Eg. a state has 5 provinces, and a furniture industry, for the movement of people and goods from those provinces to the factories etc. etc.
That said, I'd like rail, road and ports to be all seperate developments. Roads, a minor development until later in the game when extensive road networks are necessary, should not replace actual railroads, but rather in late development reduce their efficiency (while roads, themselves, offset and improve upon this). Ports, self explanatory.
What about canals too? Very important in that era: Eg, Grand and Royal Canals in Ireland, until the 1860s and '70s, were more and later as important as rail transport, only being surpassed in the very late 19th Century.
