Occupation numbers of trains or busses are calculated with a model of finite amount of train stations. We apply a random amount of persons entering or leaving a train at each station. Assuming distributions and volatility models used within financal mathematics we show a dependency between train occupation number, number of train stations and distribution of transfer passengers at train stations. We apply an process for optimization of the occupation number, as used in financal mathematics. The optimization is achieved by variation of a few parameters: the number of train stations, the homogenity of passenger transfers at train stations and the relation of train capacity to amount of transfer passengers.
