K'enx Model Roller Coaster with PLC Control System
A blast from the past! Check out the first model roller coaster I ever built that utilized a PLC. This one is only partially 3D printed and featured my first Cable Lift hill. It's very cool to look back and see how far the coasters have come.

This is a video of my Knex coaster which has a computer controlled block system using Arduino and Raspberry Pi!
I had a KNEX roller coaster as a kid the tracks didnt really work very well but i also created other fun rides with it i had the motor for it too wich was sold separate
there ıs ğ
Dude it was as if you were speaking a foreign language around time stamp 7:13 -7:16 you had my head spinning, lol. You were definitely speaking that oh so rare and difficult language called Nerd-a-nese. But really cool none the less. You went on as if we all were grasping what you were speaking. I guess for engineers it's typical jargon.
Any updates on this project so far?
Just wondering what qualifications do I need to get into rollercoaster control systems? I'm a currently a business system developer (Perl and Python) with a computer science degree, but my experience with real time systems is limited precisely to porting another rollercoaster youtuber's single block control example ladder logic program to OpenPLC so I could fiddle with it myself on screen without paying loads of money for the software he's using. I have an A-level in electronics and seem to have a tendency to tie my brain in knots with what-if scenarios which could actually be useful for thus kind of work. Also is there rollercoaster simulation software that would let me hook programs into sensors and brakes, motors etc on the sim?
As a former ride operator, for a wooden roller coaster, what you have done is amazing. The coaster I operated was older, converted from manual operation to pneumatic when it was relocated. The block system was run by sensor tech originally, no PLC but in the last 25 years since I worked at the park it has been upgraded to full PLC control and contains enhanced safety features such as dual operator dispatch. The block zones are the load/unload platform, Lift, final brake run. As this is an older coaster with a curved brake run, it runs on skid brake technology, including the load platform. WHen the coaster originally was built it contained an additional brake on the second turn around, which served more as a trim than a block zone. However it could have been modified to a block zone but the rides momentum for the 2nd half would have been boring. This brake run is very similar to Hershey Park's comet brake run which sits on the turn around above the station. When the owner of the park purchased the ride and relocated it, the trim was removed completely as there was no benefit for the brake run during early operations as the ride only operated with one train... came with 2, but both trains underwent a massive overhaul which required a ground up rebuild, the 2nd train took longer than expected. This coaster is known as one of the Comet Triplets, designed by Herb Schmeck, out of the comet triplets, all of which are operating to this day, it is the only one to still operate with Buzz Bars which allow the rider to experience insane ejector airtime. It is also the only one of the triplets that do not require the rider to wear a seat belt. It amazes me the advancements in PLC and safety technology since I worked at the park in the early 90's compared to what they use today... honestly it could really run like your Unsupervised Mode... but obviously that cannot happen due to insurance and safety regulation but the new control system is programmable to be fully automated, and pretty much as, the only operator input is required for dispatch and getting the train perfectly aligned with the load gates. For those who haven't figured it out, the ride I am talking about is The #1 Wooden Roller-coaster in the world... The Phoenix at Knoebels in Elysburg, PA
what software did you use to draw it?
The ride was designed in Nolimits. That software allows you to export the layout to a 3D design software like Fusion 360 where I did all of the design.
really beautiful
What if all 3 trains are disabled does it do 0 train operation
Nice job. You're going to achieve your dream !!!
Saw this amazing project at the First world championship in Houston. It caused the fire alarms to turn on 😂... Anyway the people of rockwell managed to fix it.
how long did it actually take?
The chain lift problem at 9:21 with block zone happened to me before on a irl coaster and I was stuck at 90°
I haven’t seen anyone else on CZcams do something like this. I’m impressed.
Dude, this is an amazing project! I'm currently a junior in an automation engineering major, though mine is geared towards HVAC controls for the most part. I recognized the Rockwell Automation controls you used, as I have used them in some of my labs. One of my dream careers was the roller coaster park industry, and just watching this video reignited my drive to get myself there in the future!
Aaannndddddd,,,,subbed
3:30 CNC machines also build guitars! Handmade guitars are often great, but incredibly labor intensive and therefore usually expensive. Certainly companies use them for financial reasons, but there are some aspects of the process that CNCs just simply do better. The guitars that best combine quality and affordability are mostly CNC with some help from human hands.
What happened to the living room coaster
Had to put it on pause for another project. I am currently building a smaller coaster for my wedding in December.
@@JaredHolladay kk
Are you going to make a video on that coaster?
Fascinating! Great job
Unbelievably incredible! Wish you loads of success in life with the talent of yours.
This is sick! How much would you say the entire project cost?
This was probably somewhere in the neighborhood of $35k so I was glad to have a sponsorship from Rockwell for this.
@@JaredHolladay yeah I don’t have $35K laying around lol. I’m studying computer engineering right now and I’m most definitely going to take on a smaller project similar to this.
@@Pdr-kx3qg Awesome! and don't count yourself out yet! This whole thing started with a conversation with the faculty. Always worth asking them if they'd be interested in supporting you! SLC 500 PLCs are fairly cheap on Ebay so that may be a lower-cost option for your project.
You should add plc control to the Lego coaster set
He did it again! Great work Jared, very inspiring.
knex also left a deep impression in my life
How did you progress from the nolimits2 program to making an actual 3d printed piece? What software was used for this step? Excellent video.
If you have the professional version of NL2 you can export the track spline as a .csv. You can do some math in excel with the csv file to scale the data and create the rail and centerline for the track. Fusion 360 has a function called import spline csv that you can use to bring that data in and after that you're off to the races. Print my ride has a great tutorial on how this is done czcams.com/video/7zUMft1ZAg4/video.html
@@JaredHolladay Thank you for your reply. I am helping my wife construct a small scale village with a bunch of amusement rides and a roller coaster would be a great addition.
I love that feeling at end of a project checking the result.Adrenaline like a pilot in flying would be released.
I’ve been an electrician for years, and recently started working at a Disney park on 3rd shift (while the park is closed). I found your videos after my first week on the job and have revisited a few times to better my understanding of the “nervous system.” I perform preventative maintenance on all these components! From the prox/speed/brake sensors to the drive motors and the vfd/plc cabinets, your model is spot on! I see all of this equipment nightly. Thank you for this detailed description, I can’t wait to see what you design & create in the future!
ABSOLUTELY AMAZING! I worked maintenance at a amusement park dealing with those very systems. The realism of your machine is spectacular! Its all there and then some! WOW!
What tool did you use to build the HMI?
The HMI in this video was made with Indusoft. It has a really nice driver for communicating with the old SLC hardware through a serial connection.. These days I have upgraded to ControLogix which is all Ethernet IP based. I have used Studio 5000 View, Factory Talk View ME, and Ignition to make model roller coaster HMIs. If you're just looking to play around with HMI software I would suggest Ignition because of their free maker license.
Jared - I enjoyed your video. I graduated from the University of Cincinnati back in 1987 with a Computer Science degree after 2 years in Industrial Design in Design, Art, Architecture and Planning (DAAP). I, too, grew up loving roller coasters and the day that The Beast opened, I ran upstairs and drew my first roller coaster - The Beast II. Although I didn't put any electronics in my roller coasters, I think you'll like seeing the 5 that I built. There is a CZcams clip of them if you search for "Mark's Roller Coasters Through the Years". I hope you enjoy them. Congratulations on your successes!! I had to comment as a fellow Cincinnatian and Roller Coaster lover. I've lived in Denver for 25 years now and get home periodically to ride The Beast and Orion and The Diamondback and enjoy some Skyline Chili while I'm home visiting family. God bless you and Good Luck with all your future electronics adventures and discoveries. (My 2nd son is in EE and loves Control Systems. He's graduating from the South Dakota School of Mines and Technology in December. Thank you for sharing your video. I hope you like mine. 🙂
Thank you Mark! It is great to hear from fellow Cincinnati coaster fans. I did watch your video as well and loved it. I especially enjoyed the wedding cake coaster because my fiancee and I have talked about doing something like that as well. The Beast is amazing to this day. Not sure if you got a chance to go this year but they rebuilt a bunch of track (and overhauled the control system) this year so now it's way smoother than it has been the past few years. I sadly don't get nearly as many Beast rides as I used to now that I live in Orlando but it is super fun to be working on real coasters for the parks down here now! Great to hear you have a son who also enjoys controls. Future theme park controls engineer as well perhaps?
@@JaredHolladay - I bet you and I could talk about the Beast all day long. Yes! I took my family home this past summer and we got to enjoy the smoother ride! I loved seeing all the fresh, unstained lumber. Can't get enough of that ride! Love the Orion now too and will only ride that in the front seat with my 13-year-old. What a rush! THANK YOU for watching my video. I need to build another one some day, but I've been busy raising a family for 28 years and I'm not sure I have that kind of patience anymore. There's a boring video out there all about the 4th coaster. It is the only one I have left. You can see it by searching "Archimedes Marble Roller Coaster". THANKS AGAIN! I hope to be able to follow your career! Congrats on your future wedding!! 🙂
Super dope man!!!
All I see is theme park sim
The office... nice
dudes smart , someone make sure he has offspring !
Do all rollercoasters with multiple train sets use fixed block, or do some use variable block lengths similar to modern railway signalling that varies block length with projected stopping distance from a given speed?
Roller coaster block zones are all fixed in length because the zones are based on where mechanical devices are located on the track to stop a train. The area in the block zone responsible for stopping the train can vary in length based on how fast the train will enter that braking area but the system is not dynamically changing the length of the zone based on the live train speed.
@@JaredHolladay Would capacity of the line increase with CBTC, or would other limits come into play like crowd control?
@@Steamtostay Technically yes. There are a couple coasters out there that use continuous loading platforms where the train never stops in the station. Instead riders board the vehicle on a moving sidewalk. These unique station platforms use several methods to get and verify the train's position so multiple trains can roll through the station with minimal gap between them. The thing is even with a cool station like this because roller coasters utilize gravity sections you still need to divide the man portion of the ride track into block zones. Reason being I have no way to stop a vehicle between the beginning of the gravity zone and the brake section at the end. Even if the ride vehicles knew exactly where each other were because there are no brakes onboard we cannot drop more than one train into a gravity zone at a time.
@@JaredHolladay The moving platform concept is very interesting; I wonder if that could be made accessible for transit purposes? Can you provide a starting point for research, i.e. one or two examples? Re gravity zones, not something I'd considered and I can't think of an equivalent in the transit signalling sector. Are braked coasters a different category of attraction? Would that permit a second train entering the gravity section earlier, depending on the capacity of the brake to decelerate? Transit emergency deceleration is usually rated at about 1.2m/s/s (at least locally), but in the context of a rollercoaster can you assume heavier emergency braking because the passengers have already volunteered themselves for more extreme g forces and are strapped in and supported rather than just holding on to handrails?
@@Steamtostay Three coasters that feature a moving load platform are Hollywood Rip Ride Rockit at Universal Studios Florida, Hagrid's Magical Creatures Motorbike Adventure at Universal's Islands of Adventure, and Wonder Woman Golden Lasso Coaster at Six Flags Fiesta Texas. Onboard braking is not an automated feature on today's coasters. Yes if there were onboard brakes you could theoretically allow multiple vehicles into the same gravity section. However, If the brakes were needed in a fault scenario you could potentially valley the train and because there is no propulsion onboard the vehicle this would cause a lengthy reset under a fault condition as vehicles would have to be winched out of the valleys.
How many of the 11' tracks are this if I may ask?
As I recall 3.25 I believe
???? 🤔😵🤯🥴 Sounds like your doing a great thing even my brain knows that part 🤣😂👍
Ok, I have to know how you got a PX from Texas Chute Out… how does that end up all the way over there?!
Please do a fully-functioning B&M dive coaster. I just subscribed.
at 1:55, what was that Intamin cable lift coaster?
Yep you got it! That's originally why I got into 3D printing model coasters. You could not buy a cable lift hill so I made one.
I think you should add some weight to the car in order to make the ride slower. The car goes too fast.
Quick questions: 1. Where did you end up landing a job at! Clearly your more than talented at this. 2. Do your interests only extended to rollercoasters or does it go beyond into dark rides, etc. I know you said you focus more on the software side, so I’d imagine something like the rise of the resistance at Disney world would peak your interest? Great stuff man!
I am a controls engineer at Universal Orlando. Yes, dark rides certainly do peak my interest as well they are just hard to replicate in small scale. Rise is certainly one heck of a machine!
amazing !!
Somehow i think i got into this operator training video for Cedar Point.
Literally subscribed within the month. Just in time to witness this cool project. I can’t wait to see it
watched the last one with great interest. I'm am AB programmer as well and would love to see the code.
Unfortunately, I can't release the code for the last coaster but this one will be far more open because I'm not working with corporate sponsors and educational institutions. I will be posting videos of code development as I get further along.
This is epic! Can’t wait
Yoooooo🔥
This is amazing! I am a ride operator at a Disney park and I recognize many of your PLC controls and this has been a really cool look at the type of ride I operate. I also operate a flat ride that uses a PLC and VFD to operate. Maybe I’ll take a look into that engineering degree after all…
You definitely should! I am a controls engineer in the amusement industry now and absolutely love the job!
Dude, this video is so close to perfect, but then you started using "effect" when you meant "affect" and ruined it for me. 😢
