ATLANTA — Norfolk Southern has resumed hump operations at its classification yard in Macon, Ga., and will soon reopen the hump at Bellevue, Ohio, as part of the new operating plan it began rolling out last month.

Both yards were converted to flat-switching facilities in 2020 after volume sank at the onset of the pandemic.

“We reactivated these humps to give ourselves some additional capacity that we need in two areas served by Macon and Bellevue. The way switching demand has evolved since 2020, there’s enough critical mass to justify returning them to service as hump yards,” Chief Operating Officer Cindy Sanborn said on the railroad’s quarterly earnings call Wednesday morning.

The move also was made to concentrate traffic at Macon and Bellevue to free up yard crews elsewhere for use in local service amid ongoing crew shortages, Sanborn says.

Macon is already classifying traffic over its hump, while Bellevue will require completion of maintenance work before hump operations begin. Once it does, NS will use half of each of the yard’s two bowls.

Officials would not say if the reopening of the humps would be temporary or permanent. “It may be short term, it may be longer term, we’ll just see how it evolves,” Sanborn says.

NS won’t be running cars out of route just to send them to Macon and Bellevue, CEO Alan Shaw says. Sending cars to humps, even if they were out of route, was standard practice before NS adopted an operating plans based on Precision Scheduled Railroading principles in 2019.

As part of its shift to PSR, NS idled the humps at six of its 10 classification yards. NS starved the humps of volume by relying more on pre-blocking cars at origins and local serving yards, as well as block-swapping en route.

Bellevue, which was the nation’s second-largest hump yard before it was idled, is at the junction of five NS routes leading to Chicago, Kansas City, New Jersey, New England, Detroit, and Columbus, Ohio, and points south. Macon serves as a corridor gateway to Jacksonville, Fla.; South Georgia; and Savannah, Ga.

Early Signs of Service Improvements

Despite crew shortages that have caused congestion, NS has begun to see service improvements from the TOP | SPG operating plan. On-time train arrivals are up 7% in July, while average train speed is up 6% and terminal dwell is down 3%.

The TOP | SPG plan — which stands for Thoroughbred Operating Plan – Service, Productivity, Growth — builds on the railroad’s 2019 TOP21 plan that redesigned its merchandise and bulk networks using the principles of Precision Scheduled Railroading [see “Norfolk Southern rolls out new, intermodal-focused operating plan,” Trains News Wire, June 27, 2022].  It aims to improve service reliability and productivity, with the expectation that both will lead to volume growth once the railroad is back to full staffing levels.

A key aim is to simplify operations so that they become more reliable day in and day out. NS took a deep dive that looked at its current operations and train schedules. It also focused on a redesign of the intermodal network.

“With TOP| SPG, we took a full-scale look at the entire network across each business segment. As such, we looked at the run times and quite frankly our stringlines of every train symbol across the network,” Paul Duncan, vice president of network planning and optimization, said in an interview this month. “We wanted to ensure that we had a simple, executable, and consistent plan. We wanted to ensure that the scheduled run times — not only between stations but for the full length of the train — were synched with what we could consistently achieve and deliver for our customers.”

On the productivity side, NS wants to makes the most of its locomotive fleet while conserving as much fuel as possible and still meeting shippers’ needs. The new plan has increased train lengths and weights, relies more on distributed power, and includes the operation of more trains that blend different types of traffic.

The number of daily trains using distributed power has increased 20% under TOP | SPG, Sanborn says.

“Where it made sense for us to blend traffic across business segments to increase the frequency and velocity of cars, as well as the service and consistency for all customers, we identified those opportunities and put those in place,” Duncan says.

NS also aimed to smooth operations at terminals and line of road by adjusting train schedules.

“We wanted to minimize meet-pass. We wanted to minimize online work events. We wanted to minimize train delay across the entire network from a schedule standpoint,” Duncan says. “So once again that feeds back to the consistency framework and why we took a look at all the schedules.”

As a result, NS adjusted the schedules of 180 of its 200 scheduled road trains, as well as its local network. Some of the schedules involve longer run times, while others call for faster transit times.

NS tweaked the schedules and train plans for some of the merchandise trains running between Chicago and the classification yard at Conway, Pa., for example. “We wanted to speed up some of our merchandise trains between Chicago and Conway to minimize delays to our premium intermodal train network,” Duncan says.

“We did reduce mainline work events at a number of locations which has improved the consistency of our performance across the mainline and contributed to increased average mainline speeds,” Duncan says. “Horsepower per ton thresholds were also calibrated across the system to balance service improvement with productivity.”

Intermodal Focus

An intermodal revamp looked at the railroad’s highest density intermodal lanes, including Chicago to Harrisburg, Pa., Philadelphia, and New Jersey as well as Chicago-Atlanta.

TOP | SPG balances the intermodal network by operating the same number of trains per direction each day where possible; simplifies routes, terminals, and traffic lanes; and increases the number of point-to-point intermodal trains. Overall, the plan increases the number of daily intermodal trains to 85 from 79.

The plan consolidates Chicago-Harrisburg, Pa., intermodal traffic, for example. Previously, NS operated one scheduled train pair between Chicago 47th Street and its Harrisburg intermodal terminal and two scheduled train pairs between Chicago 63rd Street and its Rutherford terminal east of Harrisburg.

Now, under TOP | SPG, NS has shifted the traffic into four train pairs between 47th Street and Harrisburg. After a symbol change next month, the eastbounds will be trains 28U, 22X, 20X, and 28M. Westbounds will be 263, 23G, 27G, and 25G.

The changes result in longer trains, more frequent departures, and more consistent service, Duncan says. If a container misses a train, it just has to wait six hours for the next departure, rather than 12 to 24 hours under the old plan, Duncan says.

The plan makes terminal operations more efficient and improves container cycle times, as well.

NS made similar changes in its Chicago-Atlanta service, where a second daily train pair was added and terminal operations were tweaked. Calumet Yard will handle domestic business, while Landers Yard will handle international trains. This simplifies well car assignments because domestic and international containers use different equipment, and will create capacity in both terminals while enabling NS to build longer trains.

In Atlanta, NS is relying on the switching capabilities of its Inman intermodal terminal to add blocks to trains, which also helps create greater service frequency, Duncan says.

  1. So they roll out yet another operating plan. I suppose to impress the hedge funds.
    They are still giving lousy service to their regionals in the northeast, which feed then huge amounts of business, and depend on regularity, which they are not getting.

  2. Oh no! Reopen hump yards!? What heresy. The truth is well operated hump yards can be efficiency powerhouses. And having experienced working in hump yards that are amputated into flat switching yards, I can tell you that sorting cars in a bowl where the other end is designed for pullouts is hell. The bowl is just that, actively through gravity resisting cars rolling out, and as result discouraging switching from that end. Combine that with the long leads endemic to the design, and you have a laughable but cruel task.

    Through intelligent geometric humping you can very efficiently (pre) block cuts and actually implement one of the true precepts of PSR, rather than the bastardization that it has become under the current definition.

    Of course, in railroading, as in life, one is always reluctant to admit error. Better to “tweak the plan”….

  3. Hmmmm…interesting. Did not CSX just “enhance” their operating plan via North Baltimore? Head of NS Ops former head of Ops at CSX? Birds flocking together.

  4. I downloaded the latest NS intermodal schedule spreadsheet data 7/28/22 from the NS corporate website and I see only one IM train, 20Q operating between 47th St and Harrisburg and 2 trains, 20E & 20W, running between 63rd St and Rutherford. That is, the published schedule hasn’t been changed to show 4 train pairs between Chicago-Harrisburg so have these changes occurred in real life or just in some NS model? I’m skeptical re: what’s reality and what’s theory when NS talks about these schedule changes. Has anyone trackside actually seen these changes manifested?


  6. Trains are still late and parked all over the mainline. Maintainers having trouble doing tests due to trains being built all day through interlockings, when we still have closed down hump yards sitting idle. Supervisors, maintainers and conductors are leaving in droves. NS trying to rehire the guys that took the $100,000 buyout as they cannot hire enough guys (New conductors have a 70% dropout rate) Trains so big that you can’t stop tripping over busted knuckles.
    The top of NS is rotten and cannot admit it’s mistakes…………..But hey, the calendar is coming back!

  7. Having been in the ARMY I learned to live with the alphabet soup of plans. Having worked for IBM and Siemens I’m also familiar with alphabet soup plans. When they don’t work after being first implemented rather than trying to fix what they screwed up someone would just add more new plans and everything gets further off base. The railroads shut down hump yards and intermodal terminals to “concentrate” on improvements. The end result is longer trains trying to stuff into fewer locations that can’t handle the increased work load. And the fix is “Several new alphabet characters to describe our latest tweaks to our original failing plan”.

  8. To the NS planning people…nothing about scheduling the old PRR Railroad is complicated. Instead of writing new plans and schedules to fail, get out the history books (i.e. old employee timetables!) And just follow what WORKS as already figured out by many generations of Railroaders before you! The PRR paid dividends every year of its existence fyi. Same rails. Same routes. There’s nothing to experiment with. Just do like they did before!
