While on the train to night in Chicago I saw several arcs of electricity between the train and the power rail - I believe they occur at joints on the electrical rail.
I have to believe there is some current lost due to heat and and flash, if so, how much? What is the formula or ratio? Is more energy lost during an arc of greater distance?

Your assumption seems correct, except you are looking for Power lost, not Current. The power is a function of the voltage times the current. The current will probably be a constant in this inductive system while the voltage will increase with the length of the arc.
Exact numbers for what you are asking. I don't know.

we can assume it with the price of the ticket, average use of people and the price of the station bill.... surely anything in economic should able to sustain their price or else goes bankcrupt
