Curved Track – What’s available, and what to Expect

I was recently contacted by a newer member of the LEGO Train community asking for information on the various types of curve tracks used in PennLUG. My response was a lengthy email, which has been adapted to fit an article format, and will be the content of this article.

Before I begin, I should briefly touch on some of the standards for LEGO track configurations. More information can be found on Michael Gale’s L-Gauge.org. Standard spacing practices for most layouts (including my own PennLUG) use a 16-stud spacing between the centerlines of two parallel tracks. There are two main reasons for this standard. One, it was set by LEGO, when they produced the 9-volt switch tracks. Using a turnout, a return curve, and an extra length of straight track, you get two even and parallel tracks. Two, this yields a convenient way to build track: two lines evenly spaced on one baseplate.

Every LEGO train enthusiast has probably, at some point, owned a loop of standard LEGO track. Any number of straight sections closed off by the small curve tracks you’d find in any 9-volt of Power Functions set. These tracks are known as “R40”,  as they have a radius of 40 studs.

LEGO® 9v Train Track Geometry: by Ashi Valkoinen

Understanding LEGO® track geometry, and best track layout practices, can be a little tricky for fans new to the hobby. And even veteran builders can learn new things about how the various LEGO track pieces can be used to create new layouts. Fortunately Hungarian LEGO train builder Ashi Valkoinen has written an excellent PDF on LEGO track Geometry, which we are happy to share with our readers here on Brick Model Railroader. It’s a great resource for any one who wants to understand better how to work with LEGO track.

You can read the PDF here, or you can download Ashi’s original PDF on LEGO 9v Train Track Geometry from the link bellow.


And if you are invested in seeing more of Ashi’s work be sure to visit his Brickshelf gallery and Facebook page though these links.

LEGO® 9v Train Track Geometry by Donát Raáb


The Importance of an A/D Track

A common trend when designing an L-gauge layout is to attempt to pack as much track as possible into a space. We all like to show our trains, and, unlike buildings or scenery, we need track space to do so. Often we set up our railway yards as display areas, where visitors to our layouts can see the scope and variety of our creations. This works well until we get to our favorite part, moving the trains.

A standard ladder yard design works great as a display case. Trains are lined up in long even rows, waiting for their turn to run out onto the mainline. A problem arises, however, when you want to build up a new train consist from cars parked in the yard, especially if they are not already in the order needed. In order to shuffle cars around, it’s usually necessary to pull something out onto the mainline, where it could obstruct, or “foul”, the train that is running on that track.

Enter the A/D track. By adding a single Arrival/Departure track to our yards, we can eliminate fouling the main. The A/D track is a simple siding that sits between the mainline and the yard. This track can be used as an area to build up and then stage trains until they are ready to go. Cars can be shuffled around without interfering with any trains that are running around the layout. When it’s time to swap trains, the switches on both ends of the siding are thrown. The train on the mainline comes into the siding (the Arrival) while the train in the siding goes out onto the main (the Departure). The arriving train can then be broken down, if necessary, and shuffled back into the yard.

For small layouts with only one or two trains, an Arrival/Departure track may not be necessary. For larger layouts with busy mainlines, however, an A/D track can really help improve operations, keeping the mainline running while work is being done in the yard. For visitors to the layout, there is no break in the action, and for operators, there is more fun and less “Hand of God” shuffling of cars. Adding an A/D track is one small step in moving from “LEGO Display” to “Model Railroad”.
