Eastbound Hump Reopening Temporarily at North Platte

Yes, my carman friend told me that a few weeks ago.
They open the EB Hump whenever the east bound traffic gets backed up substantially to warrant its use.

A crack in the PSR wall?

Cars leftover from the ‘97 meltdown?? (sorry, I couldn’t resist... ;^)

Sir! You jest!!! There are no cracks in the PSR wall and cannot be. It's got the word precision in it which means.....it must be perfect. No flaws whatsoever. Everything's running great! They just re-opend the one hump because...... precision!!!

At various times, numbers like 1,200 or 1,500 cars per day were needed to make a hump viable.

Maybe that's the magic number on UP?

UPS Peak Season is rapidly approaching.  Time to get other freight clogging up the mains out of the way.

But PSR is infalllible, like the MMJYR they ran the other day to get two light units from Mojave to Yermo, the
epitome of precision and cost control.

Out 

Apparently they reopened the car shop in De Soto too?

I belive De Soto and NLR Jenks were both reopened in the laat couple of weeks, but in much smaller form than they were prior to the closures.

PSR deserves a lot of skepticism, but if you read the article it sounds like they are extending tracks and installing more power switches on the west hump so needed to open the east hump to offload some of the work.

So are they going to try and buy back all the equipment they sold at auction???

As one who has worked many years at hump yards, it's always seemed that as much traffic as possible should be humped, so that inefficient switching at flat yards could be reduced. At two yards where I worked, Geometric Switching allowed 9-block haulers to run, requiring 3 tracks, and a re-hump. Those 9 blocks eliminated needless push-and-pull switching in the industrial zones.

Uh yeah, sure it is!

If you are up to it, please start a thread about Geometric Switching. I would love to hear more.

We did this at Roseville when we ran the mrvfr. It was an awful waste of time on our end. The only reason for it was lack of bowl capacity. 

We may have been at RV at the same time!

Yes, the receiving yard humping had to stop while the rehumps occurred. But making a multi-block RVFR and RVOA trains significantly reduced switching at flat yards. Also did it at City of Industry for several years, with same savings at Los Nietos, Buena Park, Anaheim, and Dolores.

It is a way to improve the use of hump yards, and reduce switching at flat yards. It's always more efficient to use gravity to assist in switching. But it takes planning ... and the discipline to stop humping from the receiving yard, and do the rehumps on schedule. Precision Scheduled Railroading!
