Mark:: I was trying to show that comparison of steam vs diesel is difficult outside the box as it is inside. The performance of same model steam engine is a function of many factors including the fuel used. As I pointed out all coals are not the same, so you will require more tons of low grade coal to move the same weight over the same track than if you used a high grade coal. The ton miles moved per ton of coal will vary with the grade selected. It is a function of energy content of the fuel used. Nitro methane has a lot more power than traditional gasoline. Just ask any NASCAR affinio. <br /> <br />*** Watkins
