Now some words on the construction:
The module is built upon a plate which only serves as a means to place and to transport it, it doesn’t provide any stability, baseplates aren’t even fixed. This is required to keep the “100 percent Lego” status.
Another advantage of this is that you can even stack several modules when transported. You only have to detach the buildings (which are transported separately) and pavements which rest within the center pit. Roads stay in their place although they are detachable, too. This is required to keep the chain and drive train accessible.
Here you can see the road profile of such a module. In fact it’s just a further stage of the road system already presented , see this post. The idea was that using baseplates and road plates has quite a few disadvantages when building larger layouts and that the separation of pavements and buildings (which in reality are completely separated, too) allows more flexibility.
Roads and pavements are detachable, buildings are resting on a few pillars. The height of the whole thing is a result of the requirement of installing a monorail underground – once you lift the whole thing, you may use the space underneath for some nice features (there are quite a few ideas … ). Of course the city will have street lights which can be installed easily (but this would even be possible with the original road system).
And now – the slot cars. There are already quite a few of them – especially the full-size cars like the Impala (which already had a working suspension) have proven to be suitable for that purpose. Real slot cars have a self-steering front axle and a rear suspension which is necessary due to the unevenness of the slot roads.
So what do we have:
- School Bus (motorized freerunner). You may have already see one or two videos with this one. It is meant to be moving on the great circle.
- Ecto-1. To be honest the Ecto is not the most suitable slot car until now. A few laps are possible, but due to its weight (there’s the battery box) the car breaks down sooner or later. It will be rather used as a special feature.
- Chevy Impala Convertible. If everything is fixed properly this car may stay within the slot for an hour or so before anything bad happens.
- Checker Taxi Cab. Since this car is built to be used in the slot it is the most stable and reliable car. It will move for hours if required.
- Impala Police Interceptor. Same as the Impala Convertible.
- Roadster. No real slot car, rather used to compare the different types of vehicles. It doesn’t steer and is unsprung, so it doesn’t look too good in curves. On the other hand it can go on full speed for several laps due to its lightweight construction. It’s quite stable, too.
- Vintage Truck. Quite reliable, too, the big wheels don’t come off easily.
- CHiPs. Can’t be called a MOC, just an idea how to involve motorbikes.
- 1477. This is rather a personal reminiscence since this car (with the proper dust on it) was – apart from two 2×4 bricks – the only remnant of my Lego collection after my dark ages.
That’s why this car is featured in the pre-title sequence of the video.
