<p>[quote user="Overmod"]Sulfation and other problems result with large numbers of chemical 'cycles' between charge and discharge. (Some of this was addressed in the design of Norfolk Southern's 999.) Reading between the lines, somebody failed miserably to understand exactly what is involved with flat switching -- it's often actually the opposite of what you might expect, kicking cars up to high speed quickly and then using high levels of braking.[/quote]</p> <p><span style="font-family:verdana,geneva;font-size:small;">The original poster raised the question in the context of a road locomotive. The #999 was conceived as a yard switcher or possibly limited road switching. It failed to meet expectations. Perhaps the developers underestimated the work of switching, as you suggest. </span></p> <p><span style="font-family:verdana,geneva;font-size:small;">But if the design engineering were to properly address the work of switching, would a battery powered yard switcher be economically feasible, even though battery powered road locomotives appear to be infeasible?</span></p>
