3D printing is slowly creeping into a wide variety of sectors. Train enthusiasts can thus find an alternative to their passion by having certain 3D printed parts made that might for example not be available on the market. The 3D printers make it possible to create toys for the kids but also more precise pieces and more faithful to reality for collectors.

In this collection you can download several 3D models of trains' accessories such as rails, traffic signs, stations, buildings, etc. But also several varieties of 3D printable wagons, locomotives or trains. Some files are printable at once, others will require assembly with adhesive. In any case, do not hesitate to spend time on finitions thanks to sanding and painting.

We hope you enjoyed our selection of the best 3D printer files related to train modeling. All these STL files are 3D printable, so just download them, slice them and charge them on your 3D printer. This collection was created by selecting the best 3D models from the 3D object library Cults.

3D printed railway models, part II: Trains and buildings

In the previous article, we showed how to create a basic landscape suitable for model railways. However, what about trains, buildings, people and other details that bring the landscape to life? Let us show you how to enhance your model railway with some great techniques and 3D prints.

3D printed trains

Trains are the most important part of every model railway. It doesnā€™t matter if youā€™re already completing the tiniest landscape details or just starting to build the basics, the trains are always number one. Almost everyone (including us) is usually eager to place their train models on the tracks even without finishing the landscape. Itā€™s also useful in determining whether the tracks are positioned correctly ā€“ that should be done before we glue them to the landscape.

To test our tracks, we printed several models of locomotives and passenger cars. Some of them are printed with our Original Prusa SL1 printer and others using the Original Prusa i3 MK3S. Let us introduce you to these models with brief instructions on how to print them.


Locomotive 742 from the Mashinky game

The first and the most detailed model, frequently used in the Czech Republic, is a locomotive 742 also called ā€œKocourā€ (ā€œtomcatā€ in English). The model itself comes from the Mashinky game by Jan Zeleny. It is an intricate and very entertaining computer strategy game, in which players build their own railway empire. This model is impossible to print at an H0 scale using FFF/FDM printers because it contains a lot of tiny details. It is necessary to use the qualities of MSLA printers. We achieved the best results using the Original Prusa SL1 printer with Prusa Orange Resin at 0,05mm layer height. The locomotive can be printed as a static model, however, you can easily modify it and place the electronics inside.

The locomotive 742 is small enough to be placed in the printing area without the need to cut the model. It is better to print these models as a whole: cutting the model and gluing it later requires extra effort (e.g. to hide the seam) and doesnā€™t bring any real benefit.

When you print train models, we donā€™t recommend using the automatic supports generation. Instead, place the support points manually. This way you can be sure that all the overhanging parts are supported and there are no unnecessary supports created in places where we donā€™t want them. It is important to support all of the edges to avoid warping or peeling. Use 0,3mm support heads for tiny and thin parts of the model. Removing supports with 0,4mm diameter might lead to damage to some delicate details. If you are not sure, look at our model (see the photo below). The wheels need to be printed perpendicular to the print platform to make them as round as possible.

When the print job is done, wash the model with isopropyl alcohol, but do not cure it with UV light! First, remove all the support structures using a very sharp knife or scalpel. Once all of the support material is removed, cure the model with UV light. Next, smooth out the supported spots with a rasper or sandpaper and confirm that everything fits properly. If so, the model can be assembled and painted now. The locomotive 742 can be seen in various colors, we chose the most common red base color with a beige stripe.

ā€œKocourā€ is finally complete and ready to go. You can see for yourselves that the locomotive looks quite authentic ā€“ our thanks go to Tomas Krakora, Jan Zeleny and his game Mashinky for such an amazing model.

You can download the model from PrusaPrinters.org.

EAS freight car

The locomotive itself is really nice, but it should have some cars, too! Letā€™s print some type EAS freight carriages, also used commonly throughout the Czech Republic for transportation of wood or coal. This miniature is much easier to print thanks to fewer details. This model is also possible to fit inside the printing volume of our Original Prusa SL1 in one piece. It is better to rotate the cargo space part upside down. The chassis and wheels should be printed separately and oriented perpendicularly to the print platform to achieve a perfectly round shape that prevents the car from falling off of the tracks. You can buy the wheels and fit them into the chassis if you donā€™t wish to print them. The assembly is very easy and intuitive ā€“ you need only a few drops of super glue and proper couplers. The EAS cars are usually colored red but nowadays they are mostly corroded and dirty.

The EAS car can be printed not only using the Original Prusa SL1 printer but also the Original Prusa i3 MK3s. However, you should keep in mind that you have to use a 0,25mm nozzle and expect that some details will be lost.

You can download the model from PrusaPrinters.org.

Motorized carriage 810

The freight train is ready to go but how do we transport the passengers? Letā€™s use the legendary ā€œmotorĆ”kā€, also frequently used on the Czech tracks. We designed two versions for you: A simple motorless carriage (you need only 2 couplers and 2 axles if you donā€™t want to print them) and a motorized unit with a hole for the Bramos carriage. Keep in mind that the carriage can be bought in the Czech Republic and it might be challenging to find them abroad, though.

This model contains more tiny parts and details than the previous one. We recommend to print it with the Original Prusa SL1 printer. The print and support generation process is the same as for the locomotive 742. Choose the support head diameter according to the detail, manually place the support points and print the model using 0,05mm layers. Windows should be printed with transparent resin and with the flat side facing the printer platform (donā€™t use supports and pad).

Wash the parts with isopropyl alcohol but do not cure them with UV light! Carefully remove the support material using a scalpel or sharp knife and cure the parts only after this is done. Sand the rest of the support material and confirm that everything fits. Sand the windows with wet and very fine sandpaper (roughness 1500 and higher) and spray them with glossy acrylic clear coat. This way, the windows will be transparent enough so you can see the interior of the carriage. Donā€™t forget to color the parts before you insert the windows and glue everything together. The motorized carriage 810 is usually colored red with a beige stripe, but reconstructed units can be seen in blue with a white stripe.

You can download the model from PrusaPrinters.org.

Carriages and locomotives for FFF 3D printing

We understand that not everyone has an SLA 3D printer, so perhaps you would like to use your Original Prusa i3 to print some railway models. Fortunately, there are models designed for FFF 3D printing, which are also compatible with MSLA printers. Printing these models is quite easy ā€“ in fact, all the pictured models can be printed using a 0,4mm nozzle and 0,15mm layer height.

Buildings and small detailed parts

The trains are printed and ready, so now itā€™s time to print the static models. This means human figures, buildings, cars, furniture and an endless number of other models that will give the landscape an authentic appearance. Large static models (buildings) have one great advantage: they can be easily printed using classic FFF/FDM printers. Weā€™ve selected a couple of buildings (see below) and printed them using Prusament PLA Galaxy silver with 0,4mm nozzle and 0,15mm layer height. However, it doesnā€™t matter what color does your filament have, everything will be printed. On the other hand, various filament colors can be used in a variety of smart ways ā€“ e.g. unpainted Prusament PLA Silver can represent cement between bricks.Ā

Model railways and 3D printers are an amazing combination. There are many models available on the internet ā€“ and often for free! All you need to do is to take your time choosing the right ones. And if you donā€™t find any suitable model, you can always make your own and share it with the community. Another great thing is that even with the costs for the printer and materials included, you can still save a good amount of money when you decide to 3D print the assets instead of buying them. Plus, youā€™re getting that amazing sense of accomplishment when you create something cool entirely from scratch!

Altametris and DJI created a 3D model of a railway section in 20 minutes

nine0002 With DJI drones, Altametris has improved the security, speed and scalability of its business processes.

Can the DJI Matrice 300 RTK Aircraft with the Zenmuse P1 payload become the ultimate surveying and mapping tool? According to the representatives of the company Altametris, which is engaged in the accumulation and analysis of data for the French railway company SNCF, no doubt. And these statements were confirmed by the results of severe tests. nine0037

New level copters and surveying

On January 4, 2021, an Altametris drone specialist arrived at the SNCF railway site to test and compare survey methods. Conventional technology requires up to 40 surface control points (GCPs) per square kilometer to achieve a resolution of 3 cm. This is an energy-intensive procedure for a minimum of three hours. The alternative is to use a high-precision total station, but this takes twice as long. nine0037


So Altametris surveyed railroad tracks using surface control points (GCPs), black and white checkered plates whose coordinates are recorded by GPS Spectra. Photo: Altametris.

Both methods rely on the participation of people to control the equipment on and near the railway tracks, which creates additional risks for the operator and requires a lot of time and effort, because the complex topography of the railway is not easy to correctly and accurately map. Time and safety are key factors in successful geodetic work, and, accordingly, innovative techniques provide a significant competitive advantage. nine0037


Geodetic work may involve safety risks for workers. With the use of the DJI drone for mapping and geodetic work, travel on the railroad track will be required less frequently. Photo: Altametris.

Altametris representatives wanted to test the DJI Matrice 300 RTK quadcopter with the Zenmuse P1 payload. The company hoped for a significant improvement in efficiency and safety with the unmanned surveying solution. nine0037

The built-in RTK (Real-time kinematic) module is able to synchronize its work, taking into account the large amount of data from the full-sized Zenmuse P1 sensor, and the number of control ground points (GCP) is reduced to zero. However, Altametris did install six of these for quality control, but even so, they managed to reduce the preparation time for the operation by two hours.


Traditionally, geodetic and cartographic work requires 2-3 specialists, and one drone operator is enough, which saves money. Photo: Altametris. nine0151

Low Light Mapping

The DJI Matrice 300 RTK Aircraft is the foundation of aerial mapping and surveying, and the Zenmuse P1 payload and its full-frame sensor are the tools to take your work to the next level.

During the mission, the illumination on the site was poor, so those six GCPs were additionally installed. After the preparatory work was completed, the aircraft operator selected the mapping area and launched the DJI Matrice 300 RTK with the Zenmuse P1 gimbal. nine0037

In 20 minutes, the Zenmuse P1 mechanical shutter system automatically took 641 shots from the required five angles at each anchor point.


The DJI Matrice 300 RTK is easy to transport in its carrying case and takes minutes to deploy. Photo: Altametris.

The Zenmuse P1's Smart Oblique Capture did the job of capturing a lot of data in a short amount of time. The camera automatically tilts and rotates at each control point and accumulates the necessary array of images at the right angles. This mode, combined with a pre-programmed flight path, allows the operator to complete a complex mapping mission at the touch of a button. nine0037

To the surprise of Altametris, low light did not affect the quality of the images. In contrast, the Zenmuse P1, thanks to its full-frame sensor, provided incredibly accurate data. There were no traces of noise in the pictures. This is important, because when shooting from a distance, even one wrong pixel is a few centimeters of misinterpreted information, which reduces the accuracy of the final result.

ā€œM300 RTK + P1 combo delivers high quality and time savings for growing photogrammetry needsā€


ā€” Quentin Lemesl, Altametris

DJI Terra Software for Geodesy and Photogrammetry

The next step was to import 641 images into DJI Terra's dedicated software to create the final 3D model. The program models a ā€œpoint cloudā€ from available photographs stitched together by combining the points of adjacent frames. This cloud serves as the basis for the 3D mesh, and eventually transforms into a 3D model.

The process is automated, making it easy for beginners in drone photography and photogrammetry. The "Point Cloud" can be manually corrected if necessary if some pixels are incorrectly matched. But in the Altametris project, everything came together on the first try, which made it possible to go straight to 3D modeling. In two hours, the 3D model was already completed and ready for analysis. nine0037

Plug and fly

The Altametris operator set up the DJI Matrice 300 RTK and Zenmuse P1 in two minutes and launched the mapping mission without unnecessary delay. He simply unpacked the quad, attached the Zenmuse P1, inserted the batteries, and the system was ready to fly.

Autopilot

Quadcopters have given Altametris the ability to automate much of its workflow. Once a flight plan has been selected, which may be based on waypoints, general mapping, perspective or line surveys, a specific flight path for the operation is determined. Altametris controls every parameter: front and side image overlap, height, roll, camera angle and headroom. The final, fully automated flight results in improved accuracy and better interoperability of multiple operations on the same site. nine0037

DJI Terra software

All received data was processed on site with DJI Terra software. Integrated into the DJI ecosystem, the software takes advantage of all the features of the aircraft and camera to create highly accurate 3D models.

The software combines photo pixel analysis with available metadata to calculate the camera position of all photos relative to each other. The first result was "Point Cloud" - the basis for the automatically generated mesh. This mesh was then turned into a finished 3D terrain model. nine0037

A giant breakthrough in geodetic surveying: from satellite to copter

GCP and tacheometry methods are based on information from satellites in the Earth's exosphere. They achieve high accuracy rates due to triangulation. Achieving a given accuracy is a challenge for any alternative mapping and geosurvey technique. Altametris had the ability to directly compare the accuracy of the drone with the accuracy of the control point methods and with the results of earlier mapping operations on the site. nine0037

The DJI Matrice 300 RTK with the Zenmuse P1 payload managed to achieve a resolution of about 2 cm, which is slightly more accurate than the GCP method (capable of 2-3 cm), and this can already be compared with tacheometry methods (millimeter accuracy).

However, the main advantage of our method is the huge amount of information provided by the DJI copter. This allows you to create very detailed models of large areas in short periods of time.


Description of Altametris drone mapping process. nine0151

DJI drone surveys

Altametris predicts that the need for accurate data at large scale will increase as more analog assets are digitized. In search of the ideal analytical solution, three basic factors were identified:

  • Accuracy.
  • Speed.
  • Cost.

According to Maxence Tronier, professional drone distributor at Abot, DJI drones are the most balanced product in terms of the above parameters. Especially when it comes to large-scale surveys and mapping operations. nine0037

Intelligent combination of available metadata such as position in space, altitude from the RTK positioning module (GPS L1 L2, GLONASS L1 L2, BeiDou B1 B2 and Galileo E1 E5a) and Smart Oblique Capture automated mode (for changing the angles of the survey and centering) gives incredibly accurate results that can be obtained up to 15 times faster than traditional surveying and mapping methods.

Priced at ā‚¬12,700 ($13,200), the DJI Matrice 300 RTK is even cheaper than the GCPs + Spectra GNSS receiver used by Altametris before. The unmanned system has no limits on the size of the mapping area. Even if 55 minutes of flight time is not enough to cover the area, the built-in resume function will allow unmanned surveyors to resume work without problems after changing the battery. nine0037


Comparison of surveying and mapping methods. GNSS and total station versus DJI Matrice 300 RTK with Zenmuse P1 payload.
