Murdoch17 posted a topic in LEGO Train TechThe coaches are inspired by train sets 7715 / 7718 from the 4.5 Volt era in the early to mid 1980's. The Lego Land Railway runs the train from World City to Heartlake City with stops at Classic Town, Paradisia Coast, Duplo-Ville, Ninjago City, (where the electric loco is replaced by a steamer or vise versa for the rest of the trip) Fabu-Land, Technic Town, Fort Legoredo and the Castle Realm. (with extensions into the Forest of Failed Themes and the Outer Dimension of Galidor at certain times of the year.) As both sides are the same (even for the headlamp color), I decided to take only one picture of the ends of the loco. This model was inspired by both a 1999 version of the engine built by Flickr user legosteveb user and a couple of digital-only designs by @Sunder. The pantographs on top are inspired by set 10277. (Crocodile locomotive) Unfortunately, this is as low as they go because I built them from pictures and didn't do it right. (Oh well!) Fictional history: This electric engine (number 9028) was originally designed as a un-streamlined freight workhorse for use in the mountains of the Western half of the North American continent on the electrified section of the Lego-Land Rail-Road mainline back in 1925. The engine uses a 2-C+C-2 arrangement, which means single frame (really, it's split in two in the middle, as the curves were too tight to do one single piece, but that's just too technical.) mounted upon a set of two axles unpowered (the "2") and three axles powered (the "C") hinged with the ball and socket to another frame of the same design (the +). The unpowered "2" axles are at either end of the locomotive. As you can see, the three axles in the middle two sections are connected by drive rods. After serving dutifully for around seven years as a freight loco, the engine was upgraded to a fully streamline-shrouded passenger unit after another of it's eight-strong class was written off after a accident with a stuck Shell tanker truck blocking a road crossing. (Thankfully, the steeple-cab design protected the crew, who survived!) The 9028 was also given a higher gear ratio in it's trucks, to allow for the higher speeds that the passenger schedule called for. The engine's class has a reputation as a tough hauler, taking care of almost anything thrown at it in freight service, and plowing through the most impossible schedules as passenger engines. There have been times, however, when they have been helpless: In January 1952 engine 9030 and of the premier Lego-Land Rail-Road trains (The City of Heartlake) got stuck in the Rocky Mountains due to a large snowdrift on the tracks and 100-MPH winds in blizzard conditions. They got boxed in, and were stuck there for six days before rescue crews could reach them. (This actually happened to the real world City of San Francisco train in the Sierra Nevada's in January, 1952. The rotary snowplows froze to the rails trying to get through!) (picture coming soon) The engine features moving panto-graphs for picking up (imaginary) electricity from the overhead wires. They are both in the lowered position here, though normally the one closest to the train it was hauling would be used. The exception to this was if the rear panto-graph was knocked off or damaged by overhanging debris, which the engine would then have it's lead panto-graph raised in order to limp to the repair shop. This baggage / passenger car is called a combine which is short for "combination". All the doors can open on this train, even the sliding ones shown here. The three 1980's-style coaches are identical in every way. The observation car, the rear-most coach on the train, features a platform for sight seeing. Comments, questions, and complaints are always welcome! EDIT 12/17/19: Added revised real life pictures. Comments, questions and suggestions are always welcome!
Murdoch17 posted a topic in LEGO Train TechThe GG-1 was a class of electric locomotives built for the Pennsylvania Railroad (PRR) for use in the northeastern United States. 139 GG-1s were constructed by General Electric and PRR's Altoona Works from 1934 to 1943, although mine is used by Brick Railway Systems on the New York - Chicago route. The real GG-1"s never traveled that far west in service, due to the overhead wires ending at Harrisburg, Pennsylvania. The GG-1's served under the PRR, then Penn Central, and onto Conrail and Amtrak, until finally a few went to New Jersey Transit, with some of these units served from 1935 on the PRR to to retiring with NJ transit in 1983. The model seen here is painted in this fictional Brick Railway Systems blue and red color scheme. This means the engine will be pulling some stretched 1980's style passenger car painted like the ones in sets 7715 / 7718. Unlike my previous model of a GG-1, this one has no interior details. The engine features moving panto-graphs for picking up (imaginary) electricity from the overhead wires. They are both in the raised position here, though normally the one opposite the direction of travel would be used. The exception to this was if the rear panto-graph was knocked off or damaged by overhanging debris, which the engine would then have it's lead panto-graph raised in order to limp the the repair shop. The loco features Anthony Sava's sliding middle axle design. This means the middle axle out of the three on the bogie closest to the middle of the loco slide laterally back and forth to allow the engine over switches and curves that would be normally to tight to maneuver. These special bogies are used twice of course: one for each half of the loco. The two outer wheels closest to each end are connected to the inner bogies via cup-and-ball parts. This allows them to swing freely and not bind up while still representing the right amount of wheels for a GG-1 loco. The coaches this engine will pull are inspired by train sets 7715 / 7718 from the 4.5 Volt era in the early to mid 1980's. The doors should be printed like these: http://alpha.brickli...Color=5#T=C&C=5 and http://alpha.brickli...e?P=4182p05#T=C I already have 75% of the parts for this model, including all but one door. Here is the LDD file for the engine by itself: http://www.moc-pages...1461783587m.lxf ...and here is one with the coaches and engine: http://www.moc-pages...1461783797m.lxf According to a Facebook comment made to my post on the LEGO Train Fan Club page, the engine I built look similar to this bi-centennial Conrail-era unit: Comments, complaints and questions are always welcome! (This page will be revised again when the cars are built In Real Life.) Recently, I discovered this neat website on the GG-1's, called the GG-1 homepage, which was last updated in 2002. It features some cool stuff and hard to find info though so here is the link: http://www.spikesys.com/GG1/
