I would highly prefer to use volunteer labor with how it greatly benefits the Western Railway, completion of which will speed up our efforts in the other sections. Using volunteer labor along with colonization should also hopefully help drive peasant migration east. For the other points I would like to start courting the favor of France friendly factions as well as the Army, while leaning on that favor for cheaper materials procurement. We can afford to delay labor procurement for one turn for budgetary reasons, I'd prefer to leave a decent amount of funding unspent in case of cost overruns.
