I understand that large steam locomotives, even the so called "balanced" ones, could really "pound" a track because of the up and down movement of the side rods and counterbalanced drivers. Track then was the segmented, bolt joint "clickety clack" rail. <br /> <br />Nowadays track is welded in long segments. It seems (might be a perception on my part) that it's heavier, too. My primitive understanding is that diesel and electric locomotives still bring stresses to the track, but that it's much different than a steam locomotive. <br /> <br />So, my question is this: Would today's heavier, welded rail withstand the stresses of yesterday's road freight steam engines better, or worse? <br /> <br />My notebook and pen are out awaiting the physics and mathematics answers. <br /> <br />Erik <br /> <br />
