You have decided to be a part of the growing European railroad boom. All over the continent rails are needed to connect disparate regions for business and recreation.
As your lines cover more ground it is likely that they be coveted by the very governments you have chosen to support. Eventually they will nationalize your work. Victory will come to those most able to merge the private and public demands.
You may be the mogul that creates the Orient Express but eventually all of your hard work will become property of the people.
