Introduction: How to Make Electric Remote Train From a Cardboard?

About: Do it yourself "DellaiSam" is a YouTobe channel where you can see how to do cool, interesting homemade things with your own hands, from electronics, wood, metal and everything else that we have at ha…

In this article, we will show how to make a railroad from cardboard and lids, as well as a remote control with which we will manage the train.

We will need:

- Motor with gear

- old USB cable with socket

- a piece of elastic tin

- caps from plastic bottles

- a piece of plastic (you can take the old CD-ROM)

- Soldering iron, wire cutters and other tools.

Step 1: 1 We Make the Train.

First of all we cut out the base of the train as in the picture.

Then we mark the place for the engine and make a seat for it.

We also make holes for the axis of the gearbox where we install the wheels.

Step 2: ​Making Wheels

We prepare the caps, cut off the excess part and smooth the edge; we make small covers with the same size as the large ones.

Cut a circle from a CD or similar plastic a few millimeters more than the prepared caps.

Step 3: ​Making Еlectro Wheels

We wrap copper wire on large wheels, after sanding it from varnish, these wheels will be electrically conductive.

Fix the wire with super glue on the cap.

Step 4: Sliding Contacts

We select a pair of capacitors of approximately the same diameter as the axis of the gearbox shaft and disassemble them. We need only the external aluminum part of the capacitors.

We put the "P" shaped wire on the axis of the gearbox and fasten it by installing a 3 cm wire.

We dress the sleeve from the condenser onto the axle and fill it with super glue so that our construction holds well.

Step 5: Sliding Brushes

Install the prepared gear on the train frame and glue with thermal glue.

We make two sliding contacts from the wire, which will slide along the aluminum sleeves on the gearbox axis.

At the ends of the wire we make hooks and we hook on the gum, so that there is good contact.

To the other end we solder the wires and connect to the motor.

Step 6: We Collect Wheels

We solder the wires from the electric wheels onto the axle, the plastic circle with glue also onto the axle, and the lid on it, the rest of the wheels are done in a similar way only without electrical contacts.

Step 7: ​We Collect the Train Body

Step 8: We Assemble the Body and Wheels of Cars

Step 9: The Manufacture of the Railway.

We cut the cardboard into long strips; these will be rails and short for sleepers. Also we cut out the connecting places as in the picture.

We tear off a strip of usual kitchen foil and we wind it with rails.

Step 10: Strengthening Compounds

Glue the rails wrapped with foil to the cross ties and connect. When gluing in the joints, we make a gap of about 3 mm so that when collecting the road there is a better contact.

It should look like in the photo. We try to make a road with a large diameter, so the train keeps better on the tracks.

Glue the auxiliary segments on the sides of the connecting sections so that the rails in these places do not go right and left.

Step 11: Electrical Contacts on Rails

One section is glued to a solid cardboard, there will be a station. In the corner of the station near the rail, we conduct two wires and fasten them to the rails, we wrap the top with foil to hide the wires and better contact.

Step 12: Remote Controller

In the lid make two holes for toothpicks. We put one toothpick in the center, and the second with the edge on the lid. We set the side toothpick so that it protrudes a little to 5 mm, and the rest of it is bitten off.

On the inside of the lid, glue the paper plugs and leave the toothpick sticking out on both sides.

We make rounded contacts with a metal contact lug. And glue with hot glue to the lid.

Step 13: Contacts

We also make a “P” - shaped contact and fasten the wire in the middle.

Putting them together so that one side is parallel, and the second is crosswise. The intersecting contact is insulated by shrinking.

Glue the contacts and the cover to the base of the console so that the rotating contacts of the cover are inside the fixed.

Fix the swivel cover with a cardboard washer.

Step 14: Battery Compartment

Cut and glue the compartment for three AA batteries

We also cut out contacts for batteries from elastic tin and put them in place.

We solder the wires to the compartment with batteries and glue them to their place in the console.

Step 15: Management Stick

Fix the wire on the remote and solder to the cover with the contacts.

With a rubber band, we make a loop and glue it on the side ledge of the lid, and fix the other two ends with thermo-glue on the console case. This is necessary so that when the gas is released, the train automatically stops.

Step 16: Management Stick

From the ice cream sticks we make a lever to move back and forth and collect the remaining parts of the body from the console.

Step 17: Place for Batteries

Cover the battery cover with one side glued to the body, and with the other fasten velcro.

For convenience, we attach the thread to the battery compartment so that by pulling on it you can easily reach the batteries.

Step 18: Improved Train Contact

When operating the train, there may be a loss of contact between the wheels and the rails and the toy will stop.

So that the contact was reliable, under the train you need to make two contacts that will remove electricity from the rail.

Step 19: Makes Heavy

Also, so that the train does not slip on the rails, it is necessary to put gum on the wheels, and attach a load to the train itself.

Step 20: Wagon Connection

With the wire we make hooks between the cars and glue them into place.

Step 21: Теst

We collect the railway, at the junction we join and put on rubber bands.

Connect the remote to the road, everything is ready.

We press on the gas and the engine begins to move along the rails.


You will have a funny paper railway with your own hands. All the kids will be happy to do hand-made articles. The manufacturing process requires a lot of perseverance and develops fine motor skills. And it is necessary to play a hand-made article neatly, nevertheless, it is paper and fragile. Thanks for attention.
