  1. I automated this one a while back (10 years I see now, time flies!). You need one sensor per track that you place a meter or so in front of the crossing, minding the direction of the track (if the train can come from either side on the same track, you'll need two sensors for that track). If a sensor detects a train, beams go down, when the train has cleared the sensor a timer is started to make sure the beams remain closed until the train has passed the crossing. After the timer has elapsed, beams go up. For sensors I always use this one: https://www.pololu.com/product/1132 , 10cm variant will do too but needs to be placed further away from the track (or it will detect the train on the adjacent track). Don't try the cheap Ali Express IR sensors: they don't work very well, generate a lot of false positives and so on. For moving the beams you need a motor driver, easiest way to do so is an L293D driver. Google on "L293D" and you'll find a module or Arduino shield that you can use. Read the datasheet of the 293D to understand how to connect the thing. Lights can be directly connected to the controller. As mentioned before, you need a micro controller to control the whole thing. An Arduino Uno will be the most easy thing to use, lot's of tutorials for that online. Bonus 1: Here's a video with the thing in action: Automated 7866 crossing Bonus 2: The Arduino code that I've used: #include <TimerOne.h> int LampsA=8; int LampsB=9; int MotA=6; int MotB=7; int Sensor0=2; int Sensor1=3; volatile int downtime=2000; volatile long StartTime=0,EndTime=0,CurrentTime=0; volatile bool Sensor0Activated=false, Sensor1Activated=false; void setup() { Serial.begin(9600); pinMode (MotA, OUTPUT); pinMode (MotB, OUTPUT); pinMode (LampsA, OUTPUT); pinMode (LampsB, OUTPUT); pinMode (Sensor0, INPUT); pinMode (Sensor1, INPUT); pinMode(13, OUTPUT); attachInterrupt(0, Sensor0ISR, FALLING); //Sensor 0, pin 2 on Micro attachInterrupt(1, Sensor1ISR, FALLING); //Sensor 1, pin 3 on Micro barsUp(); LampsOff(); } void loop() { do { delay(1); } while (!Sensor0Activated && !Sensor1Activated); LampsOn(); barsDown(); do { CurrentTime=millis(); } while (CurrentTime < EndTime); barsUp(); LampsOff(); //attachInterrupt(0, Sensor0ISR, FALLING); //Sensor 0, pin 2 on Micro //attachInterrupt(1, Sensor1ISR, FALLING); //Sensor 1, pin 3 on Micro Sensor0Activated=false; Sensor1Activated=false; CurrentTime=0; } void LampsOn() { digitalWrite (LampsA, LOW); digitalWrite (LampsB, HIGH); } void LampsOff() { digitalWrite (LampsA, LOW); digitalWrite (LampsB, LOW); } void barsUp() { digitalWrite (MotA, LOW); digitalWrite (MotB, HIGH); delay (1000); digitalWrite (MotA, LOW); digitalWrite (MotB, LOW); } void barsDown() { digitalWrite (MotA, HIGH); digitalWrite (MotB, LOW); delay(1000); digitalWrite (MotA, LOW); digitalWrite (MotB, LOW); } void Sensor0ISR() { //detachInterrupt (0); Sensor0Activated=true; StartTime=millis(); EndTime=StartTime+downtime; } void Sensor1ISR() { //detachInterrupt (1); Sensor1Activated=true; StartTime=millis(); EndTime=StartTime+downtime; }
  2. I love it! It resembles the original so much and it has the 80's flair all over it! I also do like the Octan version, I'd say "typically 90's", odd to see that a simple change can give the whole thing a different perspective.
  3. This is just magnificent! I love the details and the overall Futuron colour scheme, well done!

    This is incredible. The size of the whole thing, the detailing, absolutely fantastic work!!
  5. Thank you all. The conclusion is I bought a replica. I'll just have to accept it and I'll try to transform it to light gray in (a long) time.
  6. The circular windows are prints and look original.
  7. I have no idea, they look original. Thanks for the link!
  8. Thanks for the compliment on my channel! I was already afraid I've been ripped off, but... ... that is so true indeed! :D
  9. Hi all, I bought a 10020 Santa Fe set through Ebay. It was a good deal but now the package has arrived, I notice that the whole set is in light bluish gray instead of the old light gray (except for two doors at the back of the train (those aren't available in LBG)). Did it also come originally in LBG? All stickers are applied on the LBG parts. I know that around that time there was a transitional period from light gray to light bluish gray. It's also specifically mentioned on Bricklink for the 10027 Engine Shed set with an additional note: "The early production runs of this set featured Brown, Dark Gray and Light Gray elements but subsequent production runs have contained varying mixtures of Brown / Reddish Brown, Dark Gray / Dark Bluish Gray and Light Gray / Light Bluish Gray elements." Could this also be the case for my 10020 Santa Fe set or have I been ripped off?

    Hi all, I was quite pleased with the Lego city 2022 line-up of sets, so I decided to sell some older sets and buy a lot of 2022 sets. By doing so, I also "refresh" my Lego collection. Together with the new train sets, I decided to build a 2022 Lego city and shoot a video of it. Enjoy!
  11. Nice design! I tried to build it with 80's-only parts:
  12. AlmightyArjen replied to HoMa's post in a topic in LEGO Train Tech
    Very cool, definitely has a vintage vibe to it!
  13. Awesome design! I love hou you've managed to put the nose in the model. That must have been quite the puzzle....
  14. Massive, looks good!
  15. Awesome, just awesome. Looks finished and complete with lots of details. Put it on Ideas, instant buy for me!
  16. This is one awesome design, it's huge!
  17. Thanks. In total about 200 hours.
  18. @ivanlan9 I have practiced speedskating for a long time: a few studs can't hurt my feet ;)
  19. After the 80's layout I wanted to do "a project in between", which got a bit out of hand. I wanted to do a simple train crash video, but I gave it a cinematic look. Especially the turning camera which looks like the Matrix camera effect was difficult to accomplish: a lot of trial&error and timing issues were involved to get it rightly done. Enjoy the result, let me know what you think it!
  20. Love it, has the vintage CS vibe all over it!
  21. The fails video of this layout is now also available:
  22. Thanks man, appreciate your comment! How awesome would it be if they played it indeed in Billund :D
  23. Thanks for the kind comments! It has been quite some work but I'm totally happy with the result.
