Shorting rail simoleons

Half of my trains award one less rail simoleon than they indicate when I load them. If I am supposed to receive 56 according to the calculator at the bottom of the screen, the number turns to 55 when I dispatch, and only 55 get added to my total. This is pretty bad programming/math, especially when the amount earned is already less than half of the passenger count. For an arbitrary system, the least you can do is give as many rail simoleons as passengers, with higher rewards for more advanced cars.
