  1. Hey guys! After a few weeks of break I'm back and working on my test-setup for train signaling. As some of you know, I've built a small test track on my desk and wired up a lot of sensors and LEDs to program and develop a signaling system for trains. I'm finally at a point where I can drive trains over a layout that has block signaling fully working and completely automated too. Here's a video: When the train passes over the block sensor, a flag is set and it's only when the flag is removed (i.e. the train has fully passed over the signal and an additional time of 1 second has passed), that the signal switches to red and vice versa. The code only makes the block-section check it's sensors and flags get set and removed automatically meaning I have minimal code maintenance to do if I want to change anything. I have a lot more signals planned for the future including switch track signals, crossings and station signals. If you're interested, I can provide a PDF with all the signals I came up with. Let me know what you think. All feedback is appreciated.
  2. I've recently picked up the 12v controller and a signal set, and intend to pick up some lamps too. I really like both the look and the way they are controlled. I also love the way it's all controlled from one central control unit. So here's my question: Has anybody either modified the innards of the 12v controller to drive 9v or modified 12v motors and controller to rail wires to run without the central rails? I'm keeping my mind pretty open at the moment, just looking for ideas that (with the minimum of modifying aging mechanisms) that would allow me to use any part of the 12v system on a more modernly powered layout. Worst case scenario, I'll just use the controller as a signalbox and nothing more, it's still pretty cool. :)
  3. Hey Guys I found This MOC Someone Made under name of "camlegofun" who made a great simple Lighted signal! I was unable to get the picture but you can see his/her work at LEGOIdeas: Maybe we can make this become a reality? Just thought it would be good to share it, Rail Co Update: He has updated the page explaining it better and even a V2 design.
  4. This thread goes along with my earlier one about Brick Railway Systems locos & Rolling Stock (see it here: http://www.eurobrick...showtopic=93584 ) Locomotive sheds & facilities: Open sided 6-long shed: This railway shed was inspired by Lightningtiger here on Eurobricks. He designed the basic frame on this shed, and I ran with it. This photo shows how tall the shed is. That's the Southern Pacific Daylight #4460 there, it's my tallest locomotive and it clears with plenty of room to spare. (The Daylight is NOT included in the LDD file, by the way) Side view. Builders Notes: I chose the dark red parts because the Museum of Transportation in St. Louis Missouri owns one of these types of sheds in this color. They also own the 4460, so the choice was obvious... plus it was the cheapest 8x16 tile color available in the needed quantity in the entire United States. LDD fie for the Open sided 6-long shed: http://www.mocpages....1395947515m.lxf Closed sided 6-Long shed (World City style) This modular railway shed was based off set #10027, Train Shed from the 2003 theme of World City. This model features three 32x32 stud sections and 12 removable roof segments. Here we see my MOD of Anthony Sava's 2-8-4 Berkshire (top) side-by-side with my MOD of JD Davis' 4-8-4 Daylight. (bottom) They both fit, but just barely. Builder's Notes: This shed was built to resemble the 2003 set, Train Engine Shed (#10027). I made it longer by 4 tracks, and widened both stalls by 1 stud on each side. (This makes it so 8 wide trains can fit) I added a middle section, threw out the old hinge-open plan, and replaced it with 3 part modular sections. (left side, middle, and right side)The shed is capable of holding Anthony Sava's 2-8-4 Berkshire steam engine, and JD Davis' 4-8-4 Daylight side-by-side and could probably fit other engines longer than that, especially since you can build multiple middle sections. LDD file for the Closed sided 6-Long shed (World City style) : http://www.mocpages....1396033333m.lxf Locomotive Coaling Tower This is a typical steam locomotive coaling tower. It features brace-work on the legs, and a hinged flap where imaginary lumps of coal can dump to an engine waiting below. Builder's Notes: I got the idea for this model from the LEGO trains website called LGauge. No, it was not from any instructions, and I had to improvise on some parts of the model. (IE the legs' bracework!) The coaling tower with the my MOD of Sava's 2-8-4 Berkshire engine below. (for scale) The engine is NOT in the LDD file found in the first pic! The first of the seven pictures I used to build this model from LGauge.(Link to LGauge website: ) LDD file for the coaling tower: http://www.mocpages....1396009461m.lxf Coaling Tower V2 & Water Tower Builders Notes: With regards to the coal tower, I was inspired by the website "LGauge". However, unlike my previous version of said tower (seen on another creation), I have removed the fancy bracework and replaced it with simple 1x10 beams. For the water tower, however, I was inspired by my Fathers work with a smaller version of the same idea. I enlarged the basic dimensions and replaced the flat roof with a more suitable sloped one of the same type as the coal tower. LDD link: http://www.mocpages....1396273780m.lxf Railroad Structures: Switch Tower (World City Style) This is a Switch Tower designed to be compatible with the 2003 set #10027, (Train Shed) or my MOC of that style. (see above for the Closed sided 6-Long shed (World City style) I am talking about) Here is the top floor, accessible by the staircase from the outside as seen in the main picture. This floor features a main computer, used for switching and train location. This is the bottom floor, where tools are stored. It can be reached by a door under the stairs / landing. Builder's Notes: This building is 100% build-able, and features no really expensive parts. (as far a I know) The model is made to compliment my XL World City train shed, which I actually own as of April 2013. LDD file for the Switch Tower (World City Style): http://www.mocpages....1396032491m.lxf BRS Signal Bridges (double and single tracks) Here we have two signal bridges, one double track, and one single track. Single Track Double track Builder's Notes: I got the instructions for these models from a website known as LGauge, which is an older LEGO train MOC site, and modified them to suit my tastes and cheaper Bricklink pricing. LDD file for the BRS Signal Bridges (double and single tracks): http://www.mocpages....1395966918m.lxf Modular Tunnels (double and single tracks) My father's tunnels' with a update. Back in 1999 - 2005, my father kinda went on a LEGO building spree. He built the original single track tunnel, a red / white shed (later expanded to double track), a bridge using 6552's river base-plate, a Factory, and an unfinished grain elevator. i am remaking them all to show to the world via Flickr & MOC Pages. The real models have been in my fathers basement since they were built. Anyway, I recreated his tunnel, took off the 32x32 green base-plate, made them modular, and made a double track version to boot. The double track version. Single tracked version. One possible combination of the two types of tunnel. If the tunnels is placed near a curve, two tracks should be placed in front of the tunnels just to make sure trains have overhang / turning room. In theory, this should hive enough time for a larger locomotive (like my Berkshire) to straighten out. LDD file for the modular tunnels: http://www.mocpages....1343930750m.lxf Railway Girder Bridge Built from my own imagination and an old file, but inspired by my Father's bridge from 1999. Double tracking is easy with this bridge! LDD file for the Railway Girder Bridge: http://www.mocpages....1396111989m.lxf Grain Elevator This Grain Elevator features a conveyor belt to transfer "corn" (round yellow studs) to the waiting rail cars. Based on my Father's design from 2001, but with a conveyor belt, more silos (is that the right word?), and less fancy arches. I also constructed this out of white and red instead of old grey and red. Top view, showcasing my brother's conveyor belt idea. LDD file for the Grain elevator: http://www.mocpages....1396114565m.lxf Factory Originally built in Sand Red by my father in 2004-ish, this building is one of my dad's biggest creations. I modified it and brought it up to my specifications... okay, I whinged it from looking at the model. I took some liberties, (& made some mistakes) with the original model. For example: the first version had a smaller smokestack, (diameter wise) and had a different Railroad loading dock. (His dock was made from the 1990's 16 x 16 old dark grey sections, with two slopes and 4 middle sections.) Anyway, I hoped it would be of some use for some people, as it always has been gathering dust in the basement since it was built. This end of the factory has a ladder to the top of the smokestack. Inside view with the removable roof to the side. Dad never finished this part, and probably never will. As to what it is supposed to produce... that's up to your imagination! LDD file for the Factory: http://www.mocpages....1396116396m.lxf Barrett's Station This station was built between the East & West Barrett's Tunnels in 1893 by the Missouri Pacific Railroad. It was used until 1944, when the war-time traffic became too much,and the two single track tunnels were bypassed by a double track cut-through built right next door. The Station and the West tunnel were preserved, while the East tunnel was covered up and buried under a road, which was eventually named Barrett's Station Road. The site of the station was turned into a museum known as the Museum of Transportation. Builder's notes: This station was originally the Toy Shop from the Winter Village series of LEGO sets. In real life, the story I just told you is 100% true. However, the Barret's station was not made in 1893, and looks nothing like the one seen here. The inspiration for the station came from the real-life Kirkwood Station (seen here: http://en.wikipedia....Amtrak_station) ) which was built in 1893, is still used by Amtrak and is located a short distance up the track from the Museum of Transportation. The rear of the station features inside seating, a old-fashioned cash register (This piece: http://www.bricklink....asp?P=3039pb26 ) and a modern train signal computer (with this part: http://www.bricklink....asp?P=3297px22 ) where the telegraph used to be. LDD file for Barrett's station: http://www.mocpages....1396901621m.lxf Grain Elevator (fancy) Built originally by my father in 1999, this elevator was never completed. As my Dad did not discover Bricklink until 2006, it lacked several crucial parts, and remains uncompleted to this day... just another thing on the to-do list! I also did some major goofs, such as making the building one stud too thin, (it should be 16 studs wide at the base), but I hope I compensated enough by making the funnel tall enough to let the tallest official train car I could think of go through without problems. (That car is http://www.bricklink...m.asp?S=10014-1 ) I have faithfully recreated the elevator and added some parts that did not exist in '99, such as the red windscreens used a funnel, and a conveyor belt with handle. LDD file for the Fancy Grain Elevator: http://www.mocpages....1398708090m.lxf Glencoe Switch Tower I was inspired to build this Glencoe Switch Tower by set number 60009 (Helicopter Arrest) and a number of old signal towers in my hometown of St. Louis, Missouri. In the real world the town of Glencoe is the location of the Wabash Frisco & Pacific Railroad. ( Link to their homepage: ) This 12 inch gauge railway runs for a mile on an old Missouri Pacific roadbed that was once (not anymore) connected to Barrett's Station, along with several other stations. They have several steam locos, and some blue white and tan train cars which I am replicating in LEGO. However, this building is not based on any one prototype at Glencoe or elsewhere, but numerous switch towers all over the St. Louis area. The first floor features an old telegraph desk, which was used to contact stations further down the line until the telephone and eventually the computer replaced it. The top of the tower has two signal computers and a cozy fireplace. LDD file for Glencoe switch Tower: http://www.mocpages....1399834102m.lxf American level crossing (double track) Inspired by fellow Eurobricks builder Lightningtiger's level crossing, especially his design for the cross-buck. (the X thing that usually says RAILROAD CROSSING) I personally really like the use of frying pans for the lights. Here is his pic of the crossing that inspired me: LDD file for my version of the crossing: Glencoe Depot Built in 1912 for Brick Railway Systems in the small town of Glencoe, Missouri, this Depot features a wood burning fireplace and a ground level platform with four benches. Inside view showcasing the four seats (3 benches, 1 chair) fireplace, and cash register. Their is also a trashcan next to the street side door, but it is hidden from view in this shot. This station model was originally built from Brick City Depot instructions, and modified by me. The LDD file will NOT be given out. Comments, Questions & complaints welcome!
  5. [ full gallery] I have finally had a chance to photograph my semaphores. First off the signal bridge is modified version of a design I first saw by Jeramy Spurgeon. I have since seen this idea duplicated on several other layouts, but so far all of the examples I have seen have inactive signals. Sure, I had working LED signals, but then a few years back I started thinking about semaphores. There is just something nice about the changing position. So soon enough, I combined my semaphore idea with the signal bridge design. The MOC is tucked away in a dark corner of my layout and my camera batteries were dying, so I couldn't get any good video, but I was able to piece together this animated gif to give you an idea of how they look when operating. The mechanicals are fairly simple, a PF m-motor with a rubber band for a clutch. The one non-obvious feature is the two 1x1 plates just below the red and white semaphore arm. These are twisted ever so slightly to provide stopping points, the plate in back for the white and the plate in front for the red. I use an RCX to run the whole signal tower with a simple "break beam" train detector consisting of a PF LED pair in the middle shining on two light sensors, one for each track. I used a technic half pin to keep the emitted light beam tightly focused and a 1x1 plate sized hole in front of the sensor to keep as much ambient light out as possible. Because the whole setup is in a dark corner, the light for the sensor looks a lot brighter in the photos than it would normally look, e.g., I had the semaphores at one show and some of my club members were puzzling over how it sensed the trains. Given normal light levels it was a lot harder to see the light used for the sensor. The RCX is tucked away in a snug shed along the tracks, with cables coming out for the sensors, light, and motors. The program isn't complicated, but it does have a few clever tricks worked in, e.g., at startup it samples the background light level and stores that for a reference (instead of using a hardcoded value). It then does a loop to check if beam a has broken (saving the result in a variable), then if beam b has broken (again saving the result), then checks to see if it needs to change the state of either semaphore (either due to a newly broken beam or timing out since the last detection). Then loops back. Since most of the action is confined to the conditional statements, the program can complete the loop quickly and sample both tracks with a fairly frequency. I should also mention that I do not actually cut power to the track, so these are just for show. It should be fairly simple to modify this set up to control a single block on one track.
