Transcript Intro 0:00 [Music] coming up is this the weirdest locomotive on the rails today we'll examine what makes it a little different on the inside and out plus uh look at some of the most modern diesels pulling Freight in the 21st century and how they become so powerful and efficient all that and maybe a surprise or two is next [Music] [Music] CSX Abbyville csx's Abbyville subdivision in Tucker Georgia around here a lot of the action happens at night and sure some of it is pre- routine 1:03 but sometimes you see and hear something a little bit out of the [Applause] ordinary out of the darkness and into the light one of the newest and strangest looking additions to the CSX roster the front of this thing looks like an EMD but it's actually more of a GE product now that's right there's actually a webtech 6cylinder ER engine under the hood oh and to avoid any confusion keep in mind that g transportation is now a division of webtech now to really understand what's been done here we need to see one of these in the CSX ET23 daylight CSX designates this as an sd23 T4 but webtech calls it an et23 DCM and yeah I know all these numbers and designations get confusing as you've 2:02 probably noticed by now most of this thing looks like an EMD SD 40-2 well aside from the back end this giant radiator housing helps the locomotive meet tier 4 emission standards hand contributes to the unit's unusual looks according to an article posted on trains.com other changes were also made to the unit like shortening the hood for the smaller engine and adding a new control system however the yard said the EMG alternator was kept okay so if you didn't know most Freight locomotives have their engines under What's called the L hood of course locomotives are essentially just rolling generators with a diesel engine producing power for electric traction Motors that turn their wheels this is an EMD SD 45-2 that was built in 1974 with a two stroke turbocharged v20 and the engine produced 3600 horsepower this this locomotive is on display at the 3:01 Southeastern Railway Museum in duth Georgia now under the hood of this odd Beast is an inline 6 producing more than 2300 horsepower most of these are being put together at csx's heavy repair shop in Huntington West Virginia while it does resemble its former self this is a far cry from an EMD SD 40-2 EMD SD40 3:27 [Music] these were refurbished by norfol Southern but still sound great pulling a heavy train [Music] uphill unlike the WB Tech creation we've been looking at the original EMD st40 d2s had a 16 cylinder turbocharged 645 two-stroke diesel engine and 645 refers to dis placement here that's cubic 4:00 inches per cylinder now the SD 40-2 was one of emd's bestselling models and many are still on the rails today now electromotive division was once part of GM but it's now owned by Progress Rail and called electromotive diesel anyway some of these old SD40 d2s are still pretty much original [Applause] many have been refurbished While others have been rebuilt to be more environmentally friendly CSX rosters these SD40 e3s but they still have an EMD prime mover specifically a turbocharged EMD 710 v12 by now we know that steel wheels on steel rails is the most efficient way to move large quantities of freight over land but what actually makes these new 5:02 and rebuilt locomotives at the headend of those trains efficient and compliant with environmental regulations well to begin with in the 21st century we've seen the radiator sections of locomotives from both GE and EMD increased greatly in size modern locomotives need greater cooling capacity to help reduce emissions [Music] [Applause] and believe it or not the majority of the locomotives you'll see on the rails in North America are water cooled they don't use any freeze both of the engines you see here meet the epa's tier 2 locomotive emission standards the radiators on units meeting the epa's tier 4 standards are even bigger this is an EMD S70 AC T4 it has 6:01 an EMD 1010 fourstroke V12 diesel engine that's right EMD finally moved away from a two-stroke engine and also increased displacement as for GE they have the et44 [Music] AC you know it's truly amazing how much locomotives grown over the years as Builders try to maximize horsepower and efficiency CSX designates this as an et44 ah it was built in 2015 behind that is an EMD gp9 from 1956 I mentioned earlier how popular the EMD SD 40-2 was well the gp9 was the bestselling EMD locomotive of all time meanwhile this specially painted Canadian national locomotive is designated as an ET 44 AC and was built in 2019 like CSX Cen also has its own special designations for its locomotives which are different than what GE calls them these things must have some serious cooling power back here anyway modern General Electric locomotives now dominate the rails in North America the company's Evolution series has been extremely popular the first jvo as many of us call them came on the scene in 2002 these units have fourstroke turbocharged 4400 horsepower v12s with a displacement of 950 cubic in per cylinder now various iterations of the jvo are commonly seen leading long-distance freight trains Okay so we've discussed cooling but for years both GE transportation and EMD have also used turbocharging as a way to get more power out of their engines and make them more efficient here exhaust gases spin turbine blades 8:01 to force combustion air into the engine to make more power and to help control emissions some Modern locomotives use multiple turbos in fact the latest addition to amra diesel fleet the Seaman charger uses a cumin V16 with four turbochargers [Applause] [Music] okay so I'm not quite sure what's going on with the second locomotive in this big lashup but I do know turbos have issues every now and then and have to be wellmaintained when throttling up some locomotives mostly older ones can suffer from something called turbo lag when combustion air doesn't match fuel input as for other approaches to meet emissions requirements some locomotives and other machines using diesel engines also treat exhaust gases 9:01 common methods include exhaust gas recirculation and selective catalytic reduction the latter uses a fluid called defa or diesel exhaust fluid which is commonly used in the trucking industry so those are some of the ways that modern locomotives have become more efficient and environmentally friendly and keep in mind a lot of this technology wouldn't work without the help of microprocessors while the hardware and software may be new these days the trend seems to be to rehab rebuild or reactivate old locomotives and this machine is definitely part of that Trend so far I've only seen these on non-revenue trains the one we saw at the beginning of this video was leading an empty Rail train I'd imagine the sd23 t4s will eventually be incorporated into Yard Service and short distance locals now I referenced some great books while researching this video and you can find those in the description below anyway that's it for now as always thanks for watching and I'll see you next time
