The main LEGO train systems are all roughly compatible. They all use a 6 stud gauge, so with a bit of fiddling, you can use all of the systems together. If you want to be most compatible with the current track offerings, you're better off with 9V and RC/PF track. This question discusses the specific compatibility issues in more detail. There are several ...

Here is an approximation of the bridge that appears on the cover of the catalog pictured above. Unlike the version in the picture, this model uses bracket pieces to attach the arched section to the rail bed. All the pieces in this build were available prior to 1994. The arches are decorative and do not really contribute to the strength of the bridge. This ...

The larger hole is present in older 9V track as well: I've never actually done this, but I've always assumed that the hole is there so that the track can be screwed or nailed down if desired to create a semi-permanent layout. This is common practice with traditional model railroad track:

If you opt for an older system which isn't produced anymore, it's going to be very hard for you to reach a decent collection and maintain it. Even 9v which was only recently been discontinued will be hard to find, especially straight tracks. Also, 9V points were not automated, so if you really want automated points, you'll have to go back to 12v, which is ...

Unless you do extreme things it should be fine. All the gears insides the Train motors, Power Function motors and the NXT motors are made of Nylon while the pinion attached to the motor is made of metal. Image Source Since Nylon is much stronger than ABS plastic (normal LEGO plastic), the ABS would twist, tear or brake before damaging the nylon gears. ...

What could be considered a safe limit that motors can endure for an extended period of time? Their rated voltage. Motors are designed to operate at their rated voltage indefinitely, or until they wear out, whichever comes first. Exceeding this voltage means you shorten the life of the motor. Your big enemy is heat. At some point, the amount of heat ...

Track Features You can do most things that you can do with traditional model railroads using LEGO trains. This includes cross track, bridges, switches, and inclines. Cross track As far as I know, this was never released for either RC or PF trains. As you noted, there was a cross track part for the 9V trains. If you aren't aware, 9V, RC, and PF track is ...

The red car that you mentioned is Mail Van (7820). There are a number of other trains in the picture including: 7730 - Goods train (the locomotive doesn't seem to be visible) 7710 - Push-Along Passenger Steam Train (just the cars) 7750 - Steam Engine with Tender (pulling the cars from 7710) 7814 - Crane Wagon 7760 - Diesel Shunter Locomotive 7720 - ...

There is a pure way of changing the points at a track. It requires as few pieces as you like: a motor and two technic beam/bricks. This video demonstrates the principles of point changing with a NXT motor and will work with PF and RCX. You can use Mindstorms to program the events that trigger the points to change, it will cost you extra but there are ...

With the exception of evergreen themes like CITY and Duplo, it's not easy to predict when sets are released. Based on trends of the last 11 years, I've included the last 20 train sets that have been released in a table: At least one train set has been released each year apart from the year 2008. The table marks an average of 1.66 train sets per year. It's ...

I say this as having been a model railroader (http://zoorail.wordpress.com) for more than 10 years. You will never get the level of detail, scale or even perhaps value with Lego railroad sets as compared to normal model railroading but I just bought two Lego Train sets 7939 and 3677 and was blown away by the care that has not only gone into how they look but ...

I'd say that an initial HO scale set was probably cheaper than a LEGO version, although a direct comparison isn't easy, and it can rapidly get out of hand once you start adding more elements in. Initial Purchases The closest I can find is probably comparing 7939 LEGO Cargo Train, which is currently selling in the LEGO shop for £130: With something like ...

You can absolutely run RC and PF trains on 12V track. You can leave out the center conducting rail since it won't be delivering any power to the train, unless you are planning to run both 12V and remote trains. The main LEGO train sets have all used the same rail gauge, which is the main thing that matters. If you'd like to use both your 12V track and the ...

5300 and 10153 are from the former 9V train system and drew power from the metal tracks. They were controlled using a transformer attached to the tracks. 88002 runs on battery power from an onboard battery box. Trains with this kind of motor can run at a set speed, or can be controlled by adding IR remote controllers. Regarding compatibility, the 5300 and ...

I'm not sure about LEGO, but Märklin, a company that specialized in building train models used simple stainless steel since 1982, chances are that LEGO did the same: Stainless steel is relatively cheap It doesn't oxidize (as the name implies) The electrical charateristics aren't good, but you don't need a very good (and expensive) material like copper for ...

I would recommend BlueBrick, which is a versatile LEGO layout editor by Alban Nanty. Apperently it has Duplo parts too, so I believe it should meet your needs. It can actually do much more for your layout planning needs (including modular tables if your club has some, for example), so maybe you'll consider it overkill as well, but since it's specifically ...

Mathematically, the largest driver wheel you can buy for LEGO is Big Ben's XL driver, with a diameter of 36.8mm. To reach 10 mph, that wheel will have to spin: 36.8 mm diameter -> 115.6 mm circumference -> 7.2 x 10^-5 mi/revolution -> 2320 RPM (!!) This means that you have to gear up a motor to run at 2320 RPM. An XL PF motor with no load spins at about ...

There is not an official API for this set or the other Powered Up sets currently. The community has reverse engineered the Bluetooth API and has created some tools to interact directly with Powered Up and Boost hubs. Here is one example: https://github.com/nathankellenicki/node-poweredup That tool supports basically every device using the Powered Up ...

According to the product description on the LEGO® webn site, the LEGO® Power Functions Train Motor 88002, can be used to motorise the Western Train Chase. The train wheels normally fit directly to this motor, so I'm sure that this train can be used on normal LEGO® tracks. Looking at the instructions for both the Red Cargo Train and the Western Train Chase, ...

The answer is kind of. I own the Emerald Night and a bunch of Thomas Duplo track. The wheelbase of the Emerald Night is wide enough that the "rails" fit inside the wheels. In fact, the passenger car fits perfectly on the track. Unfortunately, neither the engine nor the tender fit as well, due to the fact that both have pieces on the bottom that are too ...

The best way to solve this type of problem is to break it down and isolate the fault. You might find that it is easier to remove the Power Functions components from the model for some of the following: Check all connections. Disconnect each cable and re-connect everything. Ensure that the plugs are the right way around (they don't sit right if not) and ...

It's an interactive piece that makes the train perform a cool(ish) function when it rolls over it. The train has a sensor on the bottom that reads the piece and does the deed. When the train reads this red one... it stops moving, which is sorta coolish for a jealous older sibling maybe ;). Watch 3 videos explaining all the cool possibilities. (1), (2), (...

Those are the two City-themed trains that are currently available. LEGO is currently transitioning to a new electrical system for trains, so that may explain the relatively low number of trains available. There are a couple of other trains available if you are interested in something outside of the City theme. There's Winter Holiday Train (10254): And also ...

As jncraton noted LEGO is going through a transitional time now. Sadly trains are not a huge portion of their sales so it tends to ebb and flow through time anyway. So if you want a train definitely grab it while it is for sale widely. If you wait a year or two it could be gone or harder to find. There are other options however... Buy new trains on the ...

With a bit of trigonometry and some observation we can estimate a theoretical limit to the maximum length. I assume you are looking for the maximum length that would run on the sharpest possible curve, which appears to be one made with flexible track. By observing this photo of 52 flex track pieces arranged in a circle, we can estimate that each piece can ...

The main benefit is consistent performance. The rechargeable battery puts out almost the same voltage until it's almost flat, and whatever current is required with little voltage drop. Disposable batteries have more voltage, but cheap ones can't supply much current. Expensive ones can supply the current, but cost more. You'd be lucky to get 5 sets of those ...

The compression member in your design looks thin to me, and the tension member oversize (assuming they are the top and bottom respectively). I would use string for tension and the technic beams for compression as the first step. The low-part-count solution that occurs to me is going to kill the clearance under your bridge, but if that's acceptable a single ...
