The answer is kind of. I own the Emerald Night and a bunch of Thomas Duplo track. The wheelbase of the Emerald Night is wide enough that the "rails" fit inside the wheels. In fact, the passenger car fits perfectly on the track. Unfortunately, neither the engine nor the tender fit as well, due to the fact that both have pieces on the bottom that are too ...

I would recommend BlueBrick, which is a versatile LEGO layout editor by Alban Nanty. Apperently it has Duplo parts too, so I believe it should meet your needs. It can actually do much more for your layout planning needs (including modular tables if your club has some, for example), so maybe you'll consider it overkill as well, but since it's specifically ...

It hasn't been officially announced yet, but there are at least four large LEGO DUPLO train sets coming this summer. This includes two extension train track packs with straight tracks, curved tracks, switches, bridges, and train crossings. The two full train sets will include more of the same tracks. The set numbers for the extension packs are #10872 and #...

Have a look at this youtube channel: MasaoHidaka The Track is made up with standard bricks and he managed to create nice curves and even switches. The switches are quite part intensive though.

The caterpillar track and belt are both fixed length pieces. I would recommend the more versatile #57518 'Technic, Link Tread Wide with Two Pin Holes'. The part can be used to make a track as long as long as you like. The tread is compatible with: #57519 - Technic Tread Sprocket Wheel Large #57520 - Technic Tread Sprocket Wheel Small

You can use RailModeller Express or RailModeller Pro on macOS. Both feature LEGO tracks (regular and Duplo): http://www.railmodeller.com/libraries.html

The set is from the "RC / Power Functions Era", so it's meant to be compatible with those tracks. Luckily for you those are the only tracks for sale in ordinary stores today. As the answer to that question says, those tracks have "roughly the same mold" as the 9V track so the train is as compatible with those - I've also seen an Emerald Night set equipped ...

The speed regulator light being on is a good start. It looks like you have things set up correctly as far as I can tell. The first step is to identify which part is having issues. All of these parts can be purchased on Bricklink, so once you know what has failed, you can replace the defective part. Here are some ideas for testing components: If you have a ...

Warning: LEGO pieces were harmed for this answer How the switch works So, how does it work then? Well, let's open it up! The backplate is held into place by 14 pins. We'll carefully pry it open with a knife. Alternatively, we could use a drillbit to slowly scrape off the pinheads. Both methods are destructive. The backplate needs to be glued back on ...

There's an article about this topic in the November 2018 issue of HispaBrick magazine. In addition to a nice interview with the designer (Masao Hidaka), the article shows off some of the techniques used for building the rails: Technically, the design matches most of your specifications. It even includes a rather complex motorized switch: Here's a ...

All 3 of the sets you listed actually use the same type of tracks, they are Technic, Link Tread Wide with Two Pin Holes #57518. In my opinion this type would be your best option for driving a robot for a number of reasons: Since they come as links the tracks can be made any length you want, allowing a lot of flexibility in designing the robot. These are ...

This issue is one of LDD's most prominent shortcomings. Unlike other CAD software, the simplifications that LDD makes in exchange for ease-of-use restrict some creations from being assembled with any degree of ease. However, the treads in this model are possible to apply, although I cannot say how easy it would be to get them the way you would want. A quick ...

It depends on your goal, as Jason said. He illustrated pretty well why out of the package lego trains don't run on duplo track. However, if you just want something for your kids to dink around with, it is possible to build a wheeled train that will drive on duplo track without using a duplo train as it's base. The trick is to use monster truck tires or "...
