<p><span style="font-family:verdana,geneva;font-size:small;">When I asked what value one places on the objective of eliminating CO2 emissions, that question assumes that there is a cost to CO2 emissions that is now, or soon will be imposed through regulation. It appears that much if not all of the incentive to buy gensets is their ability to meet environmental regulations.</span></p> <p><span style="font-family:verdana,geneva;font-size:small;">I can’t find a reference to genset life cost, but I have learned that they cost six times more than a conventional diesel-electric switcher. Despite better fuel efficiency, I assume the life cost is higher than conventional locomotives simply because a lower life cost is not being trumpeted. What is trumpeted is the ability to meet regulations. </span></p> <p><span style="font-family:verdana,geneva;font-size:small;">When we consider the cost/benefit of battery powered locomotives, it would seem that part of the benefit is the elimination of CO2. If that objective is mandated through regulations, that objective has to be met regardless of the cost. So it would seem that battery locomotives would be cost effective no matter what they cost if they are the cheapest way to eliminate CO2 emissions. So I must conclude that the value that one should place on the objective of eliminating CO2 emissions is whatever it costs to accomplish that goal.</span></p>
