Creating Custom 90° LEGO Train Points for your Layout

This article aims to show one how too create custom 90° LEGO Train Points I made for my LEGO Railway layout. The reason for creating these custom 90° LEGO Train Points, is that the resultant 90° turn is half the width, when compared with a regular LEGO 90° Point arrangement. And hence you save on valuable Track Layout real-estate. The out of the box set-up requires 4-pieces of track instead of 3-pieces to create a 90° turn. Also by using these custom 90° LEGO Train Points, you end up with many more new layout options as a bonus.

The photograph above shows two of my Custom 90° LEGO Train Points I have made for my own layout. There modification is fairly straightforward, if somewhat fiddly.The main requirements are for you not to rush the whole exercise. The custom 90° LEGO Train Points pictured in this article are the first that I have made. Now the concept has been proven, my next batch should be somewhat neater in finish. That said, as I intend to use ballast on my finished Track Layout, most of the imperfections should be obscured.

On close inspection of the standard LEGO Train Track Point it can be seen that the turn-off begins to head towards the creation of 90° LEGO Train Point, but heads in the opposite direction. If you take two curved pieces of Track joined together and place it on top of LEGO Train Point you can plainly see this. Our goal is to modify the standard LEGO Train Point so that its final curve matches that of the two curved pieces we placed on top.

Before and after creating your own Custom 90° LEGO Train Points, please undertake an audit of all your fingers and thumbs. Upon completion, should there be a discrepancy in the values obtained, you must have done something wrong. That said, I take absolutely NO responsibility for the situation you find yourself in.


As previously mentioned, the process in creating the custom 90° LEGO Train Points requires care as part of the process requires the use of very sharp tools, including the use of a Razor Blade. If you are under 14, I suggest you convince a suitable adult to undertake the cutting parts of the exercise.

Parts List:

Step 1:


To begin the process of creating your Custom 90° LEGO Train Points we need to cut away the unwanted part of the Points as shown above. Care needs to be taken as you cut the track with a Razor Blade. I found that the standard Utility Knife is far too thick for the job as it is difficult to maneuver through the plastic.


Use a a couple of LEGO Bricks as a guide as you make your initial cuts. Once scored, you can remove the LEGO Bricks and continue the cutting process.


Extra care is needed when cutting out the corner piece. It is better to cut the area out slightly smaller than require as you can remove more plastic if needed.

Step 2:


We next need to cut a standard LEGO Curved Track piece in half. As with the the Points, use a LEGO Brick as a guide to begin with. Once the track has been scored, remove the LEGO Bricks and continue cutting the track in half.



Step 3:

You should now have the two pieces of Track cut ready too create the Custom 90° LEGO Train Points.

Step 4:


Now we need to carefully trim the two pieces of track so the fit neatly together. Use a 4×2 LEGO Brick clipped on the joint to check that the stud patter meets correctly. Remember to only take small shavings of plastic at a time from the two pieces as you can’t put it back if you remove too much!

Step 5:

Take a 2×4 LEGO Plate and wrap in kitchen “Cling Film”. Place this arrangement on an the LEGO Brick, checking to see that no holes are punched through the plastic film. Carefully place a 2×4 LEGO Tile on top of the LEGO Plate to hold the film in place and remove the bottom brick. This construction becomes the method we hold the two track pieces together while gluing. The Cling Film prevents he LEGO Plate from becoming glued too the Train Track.

Step 6:


Now apply some Epoxy Glue to the two pieces of track and but them together. Carefully place the 2×4 LEGO Plate, Tile and Cling Film on top of the track joint. The two track pieces should now be held together with the correct LEGO Stud placement.

Next, invert the points and lay them on a flat surface. Place a heavy weight on top of your masterpiece while the Epoxy Glue dries.

Step 7:


The final step is to remove any excess Epoxy Glue from the top of the newly created Custom 90° LEGO Train Points before use. Take careful note of the actual rail that the LEGO Train wheels run on for excess Epoxy.



If your Track Layout is not a permanent structure with the Track fixed too a base board of some description, I suggest you fill the reservoir on the under side of the Track at the join with Epoxy Glue. This will give the join the extra strength required when the track is attached and unattached from other track pieces.

Above is picture four Track Layout possibilities that the Custom 90° LEGO Train Points allows for. The track layouts pictured are using the standard LEGO 9V RC track.

A “Y” Track Intersection can be used to turn your Train around in place of using/building a Turntable for your Layout. As can be seen in the above image, a relatively compact “Y” Track arrangement can be made simply using the Custom 90° LEGO Train Points. The “Y” uses two Custom 90° LEGO Train Points and a standard LEGO Train Point, plus two Straight and five Curved Track pieces.


As these Track elements are modified/joined pieces, (not custom molded), and as such, they aren’t the most “prettiest” of pieces, but they are 100% functional. I have had no issues as of yet with the two on my layout, pertaining to smooth movement of trains or the strength of the piece.

As my Layout grows, I’m confident that the majority of the LEGO Train Points used will be my Custom 90° versions as they provide more functionality and as a bonus are real-estate friendly when room is an issue.
