Pinnacle of the Geep

Written by: Gary Dolzall

Electro-Motive’s superlative GP40-2, in CSX “YN2” livery, is coming soon to Train Sim World!

Electro-Motive produced its classic line of “GP” (General Purpose) locomotives, nicknamed “Geeps,” for more than half a century in a monumental production run that exceeded 16,700 locomotives. Arguably, the ultimate edition of the Geep road-switcher was the GP40-2, and this famed diesel workhorse will soon be coming to Train Sim World and CSX Heavy Haul!

The four-axle (B-B), 3,000-horsepower GP40-2 road-switcher was constructed by Electro-Motive from 1972 to 1986, sold to 27 original railroad buyers, and enjoyed a production run of 1,143 units. It is true that the GP40-2 was not the biggest seller of all Geeps (the GP9, with more than 4,200 units built holds that title), nor was it the most powerful (the GP60 at 3,800 earned that claim). But as the “Geep” little sister to the landmark six-axle SD40-2, powered by Electro-Motive’s highly successful and reliable 3,000-horepower V-16 645-series power plant, and equipped with EMD’s “Dash-2” electronics and technology, the GP40-2 was considered by many as the best among EMD’s long lineage of Geeps. Today, more than four decades after its introduction, the GP40-2 can still be found working in numbers for the likes of CSX, Norfolk Southern, Union Pacific, Kansas City Southern, and a variety of U. S. regional railroads – and that speaks volumes for the capabilities, versatility, and efficiency of the remarkable locomotive.

The GP40-2 was the direct sire of another highly successful (and similar) locomotive, the EMD GP40. Electro-Motive’s GP40 had debuted with the arrival of the builder’s 645-series diesel powerplant in 1966, and through the end of 1971, more than 1,200 GP40s had been built for 31 railroads. The GP40-2, like the entire Electro-Motive “Dash -2” line of 1972, was an evolutionary extension of EMD’s “40” line. “Dash 2” features included improved traction motors and alternators; strengthened components in the 645-power plant, and solid-state modular components in the electrical and control systems. All of which translated to enhanced reliability and operating efficiency for the GP40-2 as compared to its highly-regarded predecessor.

Among the 27 buyers of the GP40-2 were no less than 11 railroads that would eventually become (in whole or in part) members of today’s giant CSX system. The pre-CSX railroads that purchased the GP40-2 included the four largest CSX predecessors: Chesapeake & Ohio; Baltimore & Ohio, Seaboard Coast Line; and Louisville & Nashville. It included notable mid-sized roads such as Western Maryland and Richmond, Fredericksburg & Potomac. And it included inheriting a portion of Conrail’s GP40-2 fleet when CSX and NS acquired and divided that railroad in 1999. During the 1970s, Chessie System (which included B&O, C&O, and Western Maryland) had made the GP40-2 its locomotive of choice, purchasing 348 of the 3,000-horsepower road-switchers that were dressed in Chessie’s memorable and colorful livery and could be regularly frequently doing battle with famed Sand Patch. All told, CSX predecessor railroads accounted for more than 450 GP40-2s.

Today, CSX continues to employ an expansive fleet of veteran GP40-2s in road, local, and switching duties across its 21,000-mile system. CSX has, in fact, extended the already remarkable tenures of many of its units through a “GP40-3” upgrade and rebuilding program. And the successful and venerable Electro-Motive GP40-2, in classic and attractive CSX “YN2” livery, will soon be arriving as DLC for service on Sand Patch Grade in Train Sim World CSX Heavy Haul. Created in exacting detail and with realistic operating characteristics and fidelity, the Train Sim World Electro-Motive GP40-2 will join the CSX SD40-2, GP38-2, and GE AC4400CW as authentic motive power to move tonnage up and over the Sand Patch Grade route. Also included in the upcoming GP40-2 DLC will be two new contemporary and authentic freight cars ideal for manifest service on Sand Patch Grade – a 73-foot center-beam flatcar and a CSX 42-foot steel coil car. – Gary Dolzall

Coming soon to Train Sim World and CSX Heavy Haul is the successful and long-lived Electro-Motive GP40-2 in classic CSX “YN2” livery. Headed west on the CSX Keystone Subdivision through the Cumberland Narrows, a pair of GP40-2s apply their combined 6,000 horsepower to a manifest freight. Screenshots by Gary Dolzall.

The 3,000-horsepower, four-axle (B-B) GP40-2 was constructed by Electro-Motive from 1972 to 1986 in a production run of 1,143 units. Among the 27 buyers of the GP40-2 were 11 railroads that would eventually become members of today’s giant CSX system. Wearing a light dusting of snow, CSX GP40-2 6153 awaits duty at Cumberland, Maryland on the Sand Patch Grade route. Note: Screenshots may depict content in development.

On a beautiful autumn day, CSX GP40-2 6136 teams up with a “big sister” EMD SD40-2 at Cumberland Terminal, ready to haul empties up the east slope of Sand Patch Grade (above). The weather is decidedly less pleasant on another fall day at Cumberland Terminal as CSX GP40-2 6185 congregates with SD40-2s amid a pouring rain (below).

On Train Sim World’s CSX Heavy Haul Sand Patch Grade route, the task of moving coal tonnage is never ending and year-round. On the Salisbury branch at Shaw Tipple, CSX GP40-2 6102 is on the point as coal loading begins on a wintry evening (above). On a summer day on the branch, a pair of “YN2” liveried CSX GP40-2s roll coal loads over the scenic Casselman River at Meyersdale, Pennsylvania (below).

The beauty and drama of main line railroading on famed Sand Patch Grade is on display as CSX GP40-2 6217 leads an eastbound manifest up the fall-foliage-dressed west slope of the Keystone Subdivision (above), and GP40-2 6112 traces the banks of the Casselman River (below) as its lifts auto racks toward the Allegheny summit.

Via its predecessor roads, CSX acquired a fleet of more than 450 GP40-2s. Versatile and venerable, the GP40-2s have served in duties ranging from priority mainline service to local and switching work. At Rockwood, Pennsylvania, CSX GP40-2 6021 is stationed for duty on the “S&C” Subdivision (above). As seen from the engineer’s view aboard CSX GP40-2 6112 (below), a mainline freight is nearing the west portal of 4,475-foot-long Sand Patch Tunnel.

Joining the beautifully re-created EMD GP40-2 in the upcoming DLC pack for Train Sim World and CSX Heavy Haul are two new and authentic freight cars ideal for service on Sand Patch Grade, a 73-foot center-beam flatcar (above) and 42-foot CSX steel coil car (below).

Battling the rugged and unrelenting east slope of famed Sand Patch Grade, a pair of CSX GP40-2s lug a freight upgrade above Hyndman, Pennsylvania. The Electro-Motive GP40-2, in classic CSX “YN2” livery, will be coming soon to Train Sim World and CSX Heavy Haul!

  • When will this come out?

    • I don’t have any details on that right now Billy, but I would assume it will go out when it’s ready 🙂

  • When will the GP-40 DLC released? It’s more then six weeks since announcement.

    • I don’t have any details on that Daniel but I would assume it will go out when it’s ready 🙂

      • Ok thx for the info. I hope you guys can get it out soon. Can’t wait to drive this loco 🙂

  • Are there going to be new physics based suspension in the future of TSW? UE4 is now capable for Full Suspension for trains, cars and other things that can use leaf and coil springs. I hope that a Series of 1940s era Steam engines get built using this capability.

    • Always a possibility LoganTMT but there’s lots of things we need to work on and get right first 🙂

  • And so it starts 😀
    Are there plans to include more countries (Germany, the other classic RW country) in TSW?
    And do you consider releasing TSW for free WITHOUT any content, so a buyer could buy the DLC he wants? Right now, a potential buyer is forced to buy CSX Heavy Haul even though he is only interested in the GWR route. You may reach a bit more new players like this (via the lowered initial costs).

    – BS1

    • There are certainly plans to add more countries, Brett, though I don’t have any details on that right now. I’m sure we have no plans to release a product that we’ve spent millions developing for free, surely that would be a quick way to go out of business! However, we do understand that there are many that aren’t interested in CSX Heavy Haul and we are looking at ways we can detach this from the core software. More news on this in the future 🙂

  • I would Like to request something for the bell sounds that are for the ac4400cw, e-Bell Sounds alot different from ones I’ve seen before, just curious if there is a way to change them or maybe release some Modding Tools Or the SDK kit soon.

    • There isn’t a way to change them right now Mike, you’ll need the development tools to make those kinds of changes, which are still deep in development

  • Will we be able to change Train consist with different Freight cars in CSW in the future and put different freight cars and engines in our train?

    • That’s the plan kaxtell, once the tools come along, you should be able to do everything in TSW as you can in TS2017 🙂

  • We really need a CSX Business Train. That would complete Sand Patch for me! With the CSX F40PHs.

    • Interesting suggestion MikadoType4501, added to the list to consider in the future

  • when will this add on get out
    and do you now The Price On it

    • I don’t have any details to share with you right now Eivind, I’m sure more information will come along at the appropriate time 🙂

  • Are there anymore dlc’s coming to CSX heavy haul? I would like to see more dlc for this route as I anxiously await the next US route! Freight cars? Locos maybe?

    • Definitely, though I can’t share any details right now Major Dunbar. What would you most like to see? 🙂

      • As for the freight car I would like to see the CSX aggregate hopper. These cars look like the ballast hopper that came with the original NS SD40-2 LHF add on. But they have platforms on each end for employees to stand on. They can be used in both MOW service or can simply just haul ballast or similar materials. From my experience I usually see CSX haul these trains with about 40-70 cars. Sometimes not very long.

        Aggregate Hopper

        As for the locomotive, I would personally like to see the SD70ACe. There easy to identify with their large noses and wide cabs, not to mention that they are a rare locomotive as CSX was not fond of these units and only ordered 20 locomotives. And today, only 19 are still in service on CSX.

        • Interesting suggestions there Major Dunbar, those have been put on the list to consider

  • Will we see an editor or free roam option added to the game.. the main game and the HST addon seem to flatline with no real options to enjoy the scenery

    • Yes, an editor will be part of the Development Tools mentioned frequently Anthony, which are currently still deep in development and I have no further details to share right now. On the subject of Free Roam, technically the entire Service Mode is free roam, you’re free to go wherever you wish on the route 🙂

      • But we are only free to go wherever we want by foot, not with a train. There is still no possibility to go with an AC4400 to the shaw mines or Rockwood mines to load coal.
        That’s only possible in a scenario, so where in this is the “free roam”? 😉

        • No I get what you mean Daniel, and as I’ve alluded to previously, there are key features that we’ve not disclosed yet that will make the traditional “free-roam” a real possibility. More on that later 😉

          • A nice feature would be a combination of the service mode with free roam.
            So you can select a loco and the type of wagons, the start and end point like in the old TS. And the the dispatcher has to find a slot or route for the player train between all the other scheduled trains in service mode.
            I think this is very complex to achieve. But a simple free roam like in TS would be great too 🙂

            • Interesting suggestion Daniel 🙂

  • Great choice for DLC! The gp40-2 was certainly a popular locomotive! And the freight cars look good! I noticed the blue bearings on the coil car. Many freight cars today, including coal hoppers, are having these added onto cars to withstand heavier loads.
    My suggestion for this locomotive in service mode would be to have the chance to run grain trains. Grain cars were teased in all TSW teasers and trailers, but we never actually got to use them in scenarios or in service mode. The only time you see them is when their mixed in with manifests. From what iv seen, grain trains are another popular unit freight hauled over sand patch. My question is will these two freight cars be added to other services already in csx heavy haul?

    • Great suggestion Major Dunbar, will certainly relay this to the Development Team. On the two new freight cars, yes, they’re added to the other services dynamically.

  • Beautiful shots, as always, Gary. I’m crossing my fingers for a coal loading scenario at that loader at the far end of Sandpatch. Keep it coming, folks!

    By the way, I’d be happy to pay for additional scenarios or services for both CSX and GWR — something like the scenario packs available for TS.

  • Is it possible to place a GP-40 and some empty coal hoppers at the Rockwood coal loading station in the service mode?
    A long line of empty hoppers would be nice, so we have to decide them to load and rebuild a long loaded train after loading
    So we then have the possibility to spawn there and shunt around the hoppers and load some coal like we want.
    Should be easy to made as there is no AI train or train in service mode going there.
    I the would then be like a mini free roam at Rockwood. 🙂

    • Uh some grammer and spelling mistakes (from the mobile phone) I hope you understand what I mean 😉

      • Yes, I got what you meant Daniel 🙂

    • Will certainly pass your request to the Development Team, no promises but will see what we can do 🙂

  • I assume the GP40-2 will be integrated into the services tab?

    Will there be a scenario or two as well?

    • I know it will be integrated with Service Mode, Corvan. Not sure about the scenario details.

  • That looks absolutely delicious. More content for TSW is always welcome.

    How many services will there be for GP40-2? Will there be any senario content with this dlc?

    Does this mean also you may extend the route in a future add-on? 😛

    • Not sure at this stage aeterna, I know it’s going to be integrated with Service Mode but I’m not 100% on the other details 🙂

      • Service mode addition will also mean more trafic in Cumberland. Hopefully, in some services, we’ll be able to follow other services on the line, so a little bit tense traffic while climbing to or going down from Sand Patch.

        Also, please don’t be so mean to not provide some coal loading services on both facilities. 😛 For now, there is no Rockwood coal loading service.

        Thanks for the great job and continues enhancements. Keep them coming 🙂

        • Some really great feedback there aeterna 🙂

  • I see you did copy & paste the bugs from the SD-40 and GP-38 into the GP-40. In reported the bugs long time ago and several times for other CSX locos.

    -Snow on all three steps are missing on the GP40-2 (SD-40/GP-38 are missing snow on the second step).

    -The numbers of the throttle and dynamic brake notch are in the real loco backlighted, staying dark in TSW so far.

    -The needles of the amp and brake gauges don’t light up in the dark. You can see it on the cab screenshot in the article above, amp needle is barely visible, the white needle should be much brighter then the black background

    • Thanks for the thoughts Daniel, just to be clear here – the snow effect is procedural, it’s not something that’s deliberately set up, the software simply decides if it’s a flat surface that is not occluded and then allows snow to build up. If you could provide some photo reference that shows the GP40-2 gauges lit up, I’ll relay that to the Development Team to look at.

      • Illuminated gauges are standard for EMDs of the era. The handle position indicators are also illuminated, although they are often a bit dim and so not an easy thing to see in a photograph. To quote the Electrical Equipment section of the EMD service manual for the GP40-2:

        “The controller contains the three main operating handles: throttle, reverser, and dynamic brake. Nameplates identify each handle, and the positions of the throttle and dynamic brake handles are indicated in illuminated windows located directly above those handles.”

        • Really useful bit of feedback DigitalDraftsman, I’ll make sure it finds the right people 🙂

  • Looks very nice! I much prefer the shorter appearance of the Geeps versus the longer SD series machines. Is the DLC payware or an update like the “Bright Future” livery pack? Will the Centerbeam flatcar come in loaded and unloaded variations?

    Will there be any sort of Beta for the TSW development tools? I currently develop content for TSX and I have several plans for content creation in TSW. I have several assets which I have imported into the UE4 engine to get a feel for things, so I have content ready that I can use to test the tools should a Beta be on the cards.

    Thanks 🙂

    • I have no details on whether there will be a Beta on the Development Tools DigitalDraftsman, I’m sure that information will be available at the appropriate time 🙂

  • Will you be updating the physics on this locomotive, or continuing to use the incorrect power implementation you currently use in the GP38-2, SD40-2 and AC4400CW? If you’re not going to fix the physics, you really should drop the references to “realistic operating characteristics and fidelity” because that is blatant false advertising. Diesel electric locomotives should always have a positive ammeter indication when power is being applied, regardless of throttle position, unless A) the the wheels are slipping (ammeter will bounce around), B) a heavy train is pushing the locomotives down hill (ammeter can go to zero). Otherwise, it should always have a positive reading, even if the train is running at 45 miles per hour in notch 1, it will give a very slight positive reading. This doesnt mean the train accelerates, just that the drag friction equals the amp power output.

    As you currently have it modeled, the locomotive can accelerate to pre set speeds for each throttle position, at which, the amps reach zero. This is completely incorrect. You should increase the drag friction settings and the power curve so the locomotive reaches a speed in each notch where they balance each other, with wind drag increasing as speed increases and therefor equalizing amps will read higher as speed increases. For example, a light (train-less) SD40-2 might look something like this: Notch 1: 32 mph, 45 amps. Notch 2, 50mph, 65 amps, Notch 3, 65mph, 89 amps. Notch 4, 72mph, amps limited by overspeed controller for all power settings above this.

    The reason this is SO incredibly important is that on long, heavy freight trains, it is very easy to over-stress couplers and break trains in two, or cause derailements, by not smoothy and carefully controlling power and braking. The way you currently model the power, if you move the throttle from one notch to another, you can watch the ammeter go from a reading of hundreds of amps down to zero. And when you apply more power, to speed up, it will go from zero to hundreds of amps again, with no inbetween. In real life, if it worked like this, it would be impossible to keep trains coupled together because you’d always be introducing slack ripples that would break the weakest link.

    • Thanks for sharing your thoughts with us Ryan. There’s lots more work to do on the loco physics and I know there’s something that will go out soon that will hopefully address much of the concerns raised. However, we’ll continue to review the amazing feedback you have all provided us, and will keep working to get it nailed. Please do keep your feedback coming, we really do want to get this right and we very much appreciate all the support you have given us throughout 🙂

  • Nice! 🙂

    I have a general question about loco and route DLC. Will we be able to use to locos from one DLC on other routes? If I buy the GP40-2 can I use it and the other CSX locos on future US routes or only in the Sandpatch route? 🙂

    • I have no reason to think you wouldn’t be able to Daniel, that is certainly our intention so you can get the most from your hobby

  • Very exciting 😀 One question: Will this update also include some bug fixing and/or updates to gameplay/performance/game-engine/sounds etc.?

    • I don’t have any details on that Andrew, it’s possible but I’m not able to confirm anything at this point

      • Ok, I read somewhere (I think it was DTG- James that said it) that there are is an update for GWE coming out tomorrow (probably), is that true?

        • There is an update in progress Andrew but I don’t have any details when it’s going out. We typically announce updates as they’re released so I would be surprised if DTG-James has confirmed an exact day of release 🙂

          • From the Steam community:
