Like any other port, this one had an abundance of railroad tracks, with innumerable spur lines reaching out to individual terminals. One such ran behind the sulfur pile. On its back side, as they could now see, the geometric perfection of the cone had been marred by an end loader that was chewing away at it, gouging out sulfur near ground level, touching off avalanches higher up. The end loader trundled across broken pavement for a short distance and dumped the sulfur into a hopper at ground level. Angling up from that was a conveyor that carried a thick flume of yellow powder to a height where it spewed forth into an open-top hopper car. A queue of those stood along the track, already full and ready to roll. Only one of them wasn’t full of sulfur, and at the rate the loader and conveyor were going, it soon would be. "Still just purely at a demonstration, proof-of-concept scale," T.R. remarked, apparently to preempt any possible objections along the lines of this isn’t stupendously vast enough, you need to think big!
