World's Largest Train Yard Employs Unusual Ally to Sort Cars



(NET Radio) - Sitting three stories above Union Pacific's Bailey Yard, Merle Stillwell has a job many boys and girls would love - but his role as yard master is not child's play.

"It's my job to bring the trains into North Platte, get 'em into the bowl correctly, so I can tell the guy on the other end he's got enough cars to build the train," Stillwell said.

"The bowl" is an area, comprising dozens of tracks, where cars are sent - usually one or two at a time - to connect to a train different from the one they arrived on.

Bailey Yard handles 14,000 rail cars every day, 3,000 of which are sorted.

"These trains can weigh anything from 2,000 tons to maybe 25,000 tons, which is quite heavy."

To assist moving something this big, Union Pacific Railroad employs a seemingly unlikely ally: gravity.

Stillwell observes the yard from above a man-made hill - one of two at Bailey Yard - that make a big difference on the flat plains west of North Platte. The humps, as they are known, replace the work a locomotive would otherwise do.

Archaeology Dig Seeks Clues To Nebraska's Prehistoric Past



(NET RADIO) - Editor's note: This Signature Story is part of the NET News QUEST Nebraska project, a multimedia series exploring Nebraska science, environment and nature.

Matt Marvin and Steve Sarich are digging and sifting. Marvin is using a shovel to remove dirt from their excavation site, a half centimeter at a time. Sarich is carefully sifting the dirt through a screen. They're standing amidst grass, weeds and dead reeds, fighting flies, ticks and sometimes 100 degree heat in the middle of the drained Hugh Butler Lake, north of McCook. There's no Indiana Jones glamour in this real archeology world.
