Attention! The imminent arrival of the train is heralded by the descent of the crossing barrier and the resonant echo of a warning signal... A railway's essence is incomprehensible without the inclusion of a crossing and the presence of a signal box. Do you concur? I, for one, hold this conviction, a sentiment shared by my venerable acquaintance, Nicholas, the vigilant guardian of the signal box. Together with his loyal companion, Danka, they meticulously oversee the sanctity and tidiness of their domain, particularly when the inclement grasp of frost and snow endeavors to sow disruption throughout the entire railway expanse. "On my watch, none shall falter," declared Nicholas resolutely as he set about the task of liberating the rails from the clutches of snow. Every rail demands meticulous attention, for a train carrying the anticipation and laughter of children bound for the city will soon traverse this very passage. Subsequent to this job, the solace of a fireside respite, accompanied by steaming cups of tea, awaits, and the glow of festive lights adorning the tree shall be kindled. The Christmas approaches with celerity! Ho-ho-ho) P.S. Will appreciate your vote and comment: https://ideas.lego.com/projects/50a06fac-c940-406b-8d2c-3d4d82cb056e

To all LEGO train automation enthusiasts, Now that our track switch motors are out, I finally found the time to make a short clip of the first fully functional prototype of our level crossing motor. The main goal was to have a small motor specially designed level crossing barriers. We managed to pack a tiny digital servo into a brick that measures 2 studs wide, 4 studs deep and 3 brick high (16x32x28.8mm). In front, the motor has a 'square stud' to attach the barrier. In this setup I also added a prototype of our 'train traffic light' that I put on its side and added 2 red transparent 1x1 round LEGO bricks. The motor and light are controlled with our nControl software. The final motors would be printed in black, as I assume that would be the most requested color for barrier motors. Let us know what you think. This is not a final product, so all feedback/questions/suggestions are welcome!

I am sure this has been done in various variations over the years after Lego ceased production of train track crossing (last produced in 1999 for 9v tracks). I only have PF train tracks so I made my own version. Below is a Bluerender rendered version I put together in LDD and below that are actual brick built. Note that the track requires to be raised as a result, by a brick, or at least 2 plates. Update: Here is the updated crossing only image that has a center tiled section to help with 2878c01 train wheels which have a narrower wheel spacing.

Hi folks, It is one of my earlier builds that I want to share with you: an automatic railway crossing. The LDD sketch: The barriers of the crossing are powered by two medium PF motors. I use two PF receivers: one to control the PF motors of the barriers, and one to control the lights. The two PF lights are crosswise connected to the PF receiver. By this means, I am able to get flashing lights and add sound. All of this above is controlled by a Lego Mindstorms NXT and an Hi-Technic HR link (in case you don't know: with the HR link you can translate Mindstorms commands into PF commands). In the video below you can see and hear the result: In the video below you can see the result in a small train layout. A PC application controls the two trains (both having a Mindstorms NXT + HiTechnic sensor to control the train) and also the Mindstorms NXT that controls the railway crossing. Hope you like it. /Hans

A second installment in my story, the first of which you can find here. Again, just messing around with techniques, this time for water. I used decals made by ED 209 here on Eurobricks because I have no Black Falcons. Comments & Criticism appreciated.

Well, I've been lurking on these forums for a while. Time for me to contribute. Since a few weeks, my daughter and me have had a (modest) train layout with a cargo train, a passenger train, three sets of switching tracks and a decent amount of track. Having been an avid lego builder in my younger years, I really love sharing this with her. Anyway, because we were both eager to add some excitement to the setup, I decided to sacrifice two straight pieces of PF track and make a track crossing (whoa, accidents!). How I did it: The first of the two straights was cut in three pieces by cutting out a track section one stud wide on the 6th position, on both sides. Next, the center piece of this chopped up straight was disposed of its side studs. The second straight was also butchered by removing its central 2x2 and both of its central 2x1 side studs. Four more studs were removed on its sides as can be seen on the image. In addition to that, four grooves were carved out of this second straight. Tools used: a sharp knife, a miniature circular saw blade (on a Dremel clone) and a miniature grinder on the same Dremel. No glue whatsoever. It took a while to do this (+- 1 hour). To help making the cuts on the right place, I sacrificed two of my old lego 8x1 flats: it is quite convenient to click one of these on the piece of track right where it needs to be cut. The sawblade can then glide along them. (Honestly, the sacrificed pieces already suffered a dog attack in the early nineties. So it's not really a big loss ) The result: Everything fitted together: And by means of some 2x2 plates (I should probably get some bluish grey ones ), all the parts are connected: The result was added it to our layout and I must say that this piece makes the track a whole lot more interesting when trying to drive two PF trains around. With all the crashes we have had so far, I must say it's a good thing we still have my old faithful eighties firefighter helicopter around. Note: I did not consider buying a 4519 since I can't really justify its ~25€ price tag (used) for my PF setup. And of course it was just a nice silly project I enjoyed doing .

Since I'm automating lego trains, an automated level crossing can't miss in the layout. So I built one with some spare parts. I first wanted to use the 7866 remote controlled level crossing as a basis but think that the bars don't go up/down very nice: too fast and sudden. Then I discovered two micro motors I had laying around and started designing the whole thing. There are two sensors: when the train activates the first sensor, the bars will be lowered. When the last wagon activates the last sensor, the bars will go up again. In the meantime the lights will go on/off. The program is "intelligent": it can tell which sensor is activated first so the level crossing can be used in both directions. I wanted to draw the power for the system from the rails but unfortunately the motors of the trains produce a lot of electronic noise which disturbed the microcontroller and I wasn't able to filter it out. Let me know what you think of it! PS: for those who are interested, a how-it-works-video is work in progress ;)
