Tools and materials

There are some materials necessary in order to make the cargo wagon fully functional. Suggestions are provided where you can acquire these, but they should be generally available. However if you find that passing electricity is too much hasstle for you to build you can skip it. If you don't need electricity for any other wagons behind the coal wagon you don't need to wire up the connectors. You can just insert magnets into them and that is it. But I still hope you will make it with electricity, that is why I did my best to explain in my tutorials the best that I can :)

If you have never worked with soldering, there are great videos on YouTube to show you the basics. That should be just enough to acquire a skill to get this done.
There are also dedicated videos with each Loligrad build so you should be covered.

• Yellow LED 2pcs - (I would recommend yellow rather than orange, but it's your choice). I suggest Yellow 5mm. You can buy them really cheap on AliExpress.
• Resistor I suggest Metal Film Resistor 680R 0.25W. You can buy them really cheap on AliExpress.
• Magnets 6mmx3mm 4pcs - You will need these to make connectors. Wagons need 4. They are pretty cheap, especially if you buy in bulk. Check out on AliExpress.
• Flat cable - You will need this for wiring the vehicles. Try to look for old used IDE flat cables. I have tons of them in my PC scraps. If you do not have any ask your friends or search on the internet for "used IDE flat cable". Worst case scenario, you can buy cheap ones from AliExpress. We do not need to much wire from a flat cable, so one IDE flat cable will provide wiring for a lot of wagons and locomotives.
• Super glue
• OPTIONAL - Double sided sticky tape - You will need this to stick the wheel carriage to the bottom of the wagon and the roof to the chasis. That way they are removable and replaceable.
• OPTIONAL - Aluminium foil - if you want better illumintation, this can be used on the inner side of the wagon roof so it can reflect the light inside the wagon. This is mostly for us fanatics :)

Aside from usual tools used for 3D printing, here is a list of additional tools you will require to make the locomotive:

• Soldering iron - I would recommend 30W or less. Anything over 30W might burn your components. Also awoid bying cheap ones. It is not that expensive anyway and I would recommend my childhood favourite Weller. Take a look on Amazon.
• Solder wire - a little bit of soldering wire is necessary. I would recommend lead-free flux-core solder wire. You do not need a large quantity. Any small spool will do. If you know someone who works with electronics you can ask for a little bit because you do not need much. If not, you can check out on Amazon. I wouldn't recommend buying from AliExpress in this case.
• OPTIONAL - Thin tweezers - makes life easier when assembling connectors.
• OPTIONAL - Wire stripper - This will make connector assembly significantly easier. I suggest you get a cheap clamping one from AliExpress.
