Hey Tim ....LOL actually I'm just about to have some Vegemite on toast! Thanks very much for the shout out and I'm happy to help! I'm sure a loco mechanic would know the finer details on DB's , but I know that on modern EMD units down here, the traction control is used in dynamics to let the wheels "slide" a tiny bit , thus give the maximum braking effort especially on slippery rails. Crazy stuff but AC traction is very clever as you have said before. Once again thanks for the mention and keep these vids coming Sir! Cheers (frustrated wanna be Engineer) signal sparky. Gregg.
Excellent presentation. When I worked at Conrail our engineers would use dynamic braking even in level territory on intermodal trains because intermodal trains tended to have “kickers” which would cause undesired brake applications.
In April 1994, I was lucky enough to be invited to chase trains on the former Southern Ry.’s grade at Saluda, North Carolina. I will never forget the sound of those dynamic brakes howling on two practically brand new Norfolk Southern SD70s, Nos. 2502 and 2523, as they crested the hill and started their descent. That afternoon, we were treated to the same pair of SD70s, on their return trip from Spartanburg to Asheville, having to triple the hill. It was fantastic watching them run up and down the hill and reassembling the train just west of Saluda. We also witnessed a monster “Belmont” coal train descending the hill. That day was my first trackside exposure to the use of dynamic brakes. Again, the sound was unforgettable, and I enjoy employing dynamic brakes on my ESU LokSound-equipped locomotives on a grade on my HO layout, to recreate that memory. Tim, I’d love a primer on how you’re setting up dynamic brakes in your LokSound decoders and how and when you’re using them on the layout. Like you, I’m using ProtoThrottles. Thanks!
Great experience seeing those trains run down Saluda. I do plan on making more videos detailing how I mimic the prototype using the ProtoThrottle. Stay tuned!
Thanks -- I like these educational videos in between the model railroading. Bit worried that NS seems to have bought out the Seaboard Central, though! 🤣
A long time ago we had a GP35 that lit a brush fire. Couldn't figure it out at first but we found that the fire started with the dynamic brakes. The geep was on a short term lease and hadn't moved in a while. The grids got hot enough to light up the wasp nest that had been built in the housing and the fan blew the smouldering contents onto some dry grass and...instant grass fire. Another lovely day out in the wild.
The whining,the screaming....and once or twice the ' on fire' dynamic brake .....loved the sound,moreso with the GE locos. Lost that sound when New Zealand Rail had electric locos. But thank goodness the diesels were still running. Love black locos, the NS locos look great. And loving your present series too.
One hell of a rivet counter. Anyone who can describe the functions of a real locomotive only using his models is someone who is truly gifted in the art of model railroading. I'm glad you lived through the Mt. Airy run. Been there a few time by car. The grade certainly rivals many on the west coast. Still don't understand fully how DB's work, as anything electrical is pretty much over my head, but still enjoy these fine attempts to educate me. Coming from someone with direct knowledge because of your job makes it that much better. Thanks for some great channel!
Wow Tim! Everything looks so real and scale. It's just a pure pleasure watching your videos, as you are a very talented modeler that has a great eye for scale!! Thanks for posting my friend!
The former CN GP40-2Ws were purchased as mainline power and were too heavy to operate on lighter rail branchlines in Canada. CN did not feel that dynamic brakes were necessary because the majority of the track did not have grades in excess of 0.8%.
Your remark about dynamic brakes being an option (for a long time I jhadn't realized this) is spot on. For a very long time, starting with the C&O GP7's that replaced Pere Marquette steam, locomotives built for use in Michigan didn't have them. Even today,, Hujron and Eastern's "standard" diesel is a non-dynamic GP38-2.
Thanks! One of my favorite railroads that the SC gets inspiration from is the FEC and many of their original units did not have dynamics simply because Florida is relatively flat. But all of their new units have them because dynamics are no longer an option. Everything built after 1990 has them as a standard feature.
In 1979, I wrote to EMD about capturing regenerative power in batteries on locomotives. I got a short snippy hand-written note back saying that it wasn't going to happen. I now believe that that was correct, and that the weight of the batteries or the logistics of moving separate battery locomotives, along with the small amount of power that would be saved would preclude their use today
GE/Wabtec is experimenting with one in CA that is sandwiched between two GEVO units. The voltage from the dynamic brakes are being used to recharge the battery unit. You can see the example on the Wabtec RUclips channel.
Looks like your newer NS locos have been equipped with PTC antennas. Doing the same with mine. When you finally create the helix to expand the current layout, you will finally be able to use dynamic braking heading down.
Yes, I hope to have the helix in service by the middle of next year. The next project coming up will be the Gadsden Yard modules and it will be a big project due to all the wiring. I plan on powering all the turnouts.
I have my dynamic brake equipped units programmed to F7. I’ll show how and when an engineer would use dynamics after I finish connecting the yard to the upper level. Stay tuned.
@@SeaboardCentralit was something about a lightweight frame, which was taller than a normal frame yours is an example of one. AS for light weight units there were the GP9s on flexicoil trucks, RS18s with a MLW design lightweight truck and then the real light weight branchline units the 10xx GMD-1s out west and the RSC-13 later RSC-14 in the east
Wonderful follow up to your last video Tim! Great job going through the details of using dynamics vs. Automatic/Independent brakes. Just one question, will we start seeing big power show up on the new layout bringing in grain trains for ADM?
Thanks! I just brought the NS units in for these prototype info videos. I keep the NS road units on a pair of haulage rights trains I run over the line. The NS SD40s are used on an NS/SC interchange job. Since this ADM doesn’t receive unit trains it will be serviced by three GP units in local service out of Gadsden Yard eventually.
Great Info. With today's pooled or run through power practices, these locomotives could end up anywhere in the country. Do you know if the purple haze we see in Virtual Railfans videos is dynamic brake glow?
They are programmed into the locomotives. I can adjust the volume and I don’t have it on all units. Another reason why I love the LokSound V5 decoders. Thanks for watching!
Thanks! I’ve ran the C4s before. Awesome cabs but I like how the UP ES45ACCTE units perform with all three axles powered. Got to be the fastest loading GE unit I have ever ran.
Great 👍 video as,always sr by the way could you post 📫 info of the guy who weather's and detail your engine i need services on my winchester and western engines need number change and number board and other detail on one of my engine thanks sr
Good luck. Stay safe and I hope it works out for you. It can be a rewarding job with good pay and benefits but you have to accept that it is not the typical shift type work where you work for 8 hours and go home.
@@SeaboardCentral Thanks man! yeah learned that a long time ago haha, just about 2 years at this now and counting. 8 hours ain't enough for me anyway. If I can get off in under 8, sure. But if I'm there for 8, might as well be there for 10 or more lol I found you by looking up weathering techniques because I'm working on an NS grain train for myself since we get a ton of them.
No sir. I just keep some NS power for run thru haulage agreement trains. The NS SD40-2s are also used on NS transfer jobs interchanging cars between NS and the SC.
Here's a little bit more semi useless information about dynamic brakes. On a six axle locomotive the first and sixth traction motors power the dynamic brake cooling fans. The second and third and the fourth and fifth traction motors disapate their current via the toaster like elements of the dynamic brake grid. This is how its set up on the NSWSRA 81 class locomotive which also have the extended range dynamic braking fitted.

Always interesting hearing how it’s done in real life. Great explanations.
Thanks! Stay tuned. More to come.
Thanks for that. I also enjoy hearing about your work as a Professional Railroader.
Thanks! Stay tuned for more.
"He just smiled and gave me a vegemite sandwich" Great 1980's tune!!

Thanks Gary! Just got them dialed in and running great. Stay tuned. More on the way.
Beautiful layout and locomotives. Great video

Good information on dynamic brakes. Great story on the explosion of the dynamic brakes on that one trip.
Thanks Tom! Yeah that’s happened to me more than twice. The cab smells awful afterwards.
Wow Tim! Everything looks so real and scale. It's just a pure pleasure watching your videos, as you are a very talented modeler that has a great eye for scale!! Thanks for posting my friend!
Thanks for watching! I appreciate it.
Good info!! Learn something new every day. 😁
Thanks! Glad you got something out of it.
The former CN GP40-2Ws were purchased as mainline power and were too heavy to operate on lighter rail branchlines in Canada. CN did not feel that dynamic brakes were necessary because the majority of the track did not have grades in excess of 0.8%.
I know some of them are designated GP40-2LW for light weight so I assumed they were intended for those restricted branch lines.
They had a smaller fuel tank but they were still restricted because of the two axle trucks, too. They look good on your layout. @@SeaboardCentral
Learning a lot from these recent videos. Keep ‘em coming!
Thanks! Stay tuned. I have another coming out next week you might like even better. Tim

Good stuff. We always enjoy your railroading stories. Keep em coming Tim!
Thanks! Stay tuned. More to come.
Nice info. Thanks for sharing. Dave
Thanks for watching Dave!
I would also like to see how you do DB on the ESUs...thanks for the videos, Tim.
I have my dynamic brake equipped units programmed to F7. I’ll show how and when an engineer would use dynamics after I finish connecting the yard to the upper level. Stay tuned.
the GP40-2Ws were for high priority freights, CN just didn't like dynamic brakes for the most part
Makes sense but I know some of them were categorized Light Weight and that tells me that they must have been used on lines with weight restrictions.

Thanks. No idea on the purple haze. Could be some kind of glare hitting the camera lens.
Great video.
Thanks!
Very informative 👍🏽
Thanks!
Question, the flange noise in the video, is it edited into the video, or does it come from your locos? Thanks for another great video.
They are programmed into the locomotives. I can adjust the volume and I don’t have it on all units. Another reason why I love the LokSound V5 decoders. Thanks for watching!
@@SeaboardCentral Thanks for the info.
Super.
Glad you liked it.
BNSF equipped with c 4's Missing the middle traction motor , 😢 = bad
wheel hop , cool video Tim , throw 6 lbs of air and work your dyno's
Thanks! I’ve ran the C4s before. Awesome cabs but I like how the UP ES45ACCTE units perform with all three axles powered. Got to be the fastest loading GE unit I have ever ran.
We have those heavyweights are in the 3600s to 3500's numbers will showing later on order, without C 4's . Thank you
Good series….
Thanks! Stay tuned. More info next week.
I'm watching while deadheading😅
Lol
Great 👍 video as,always sr by the way could you post 📫 info of the guy who weather's and detail your engine i need services on my winchester and western engines need number change and number board and other detail on one of my engine thanks sr
Thanks! I do mine myself but there are professional guys that can do it. One is Weather My Trains. You might want to check him out online.
So how do you change the number on the number boards 🤔 sr thanks
What percentage reduction in speed do set your engines for dynamic brakes
I don’t set a reduction because I want to have the ability to keep the speed constant.
Oh nice, Im a CO for NS in Greenville lol
Good luck. Stay safe and I hope it works out for you. It can be a rewarding job with good pay and benefits but you have to accept that it is not the typical shift type work where you work for 8 hours and go home.

No sir. I just keep some NS power for run thru haulage agreement trains. The NS SD40-2s are also used on NS transfer jobs interchanging cars between NS and the SC.
Stephen u work for the rr?
I don’t know who Stephen is but I have been in the rail industry for more than 30 years mostly working as a Locomotive Engineer. Tim
Yes I do
@@SeaboardCentral that’s my dream job but now have kids so kind of can’t do that now lol
Great video thanks Tim, cheers Peter (from downunder as well)
@shaunrobertson1857 not to start a big thread on this but it's really more of a lifestyle than a job. I used to love it but not so much anymore.
