Planning a routed track

Hello all,

I've always said my dream is to make my own routed track, but always thought I didn't have the space. I've been giving this a lot of thought lately and think I've found a way around this. A storage location has become apparent in my house, so I could actually have a routed track if it can be taken down and stored in two sections.

Here's the design I've been playing with:



This rather roughly drawn plan is kind of to scale and, if built, would be 4 metres long and 1 metre wide, widening to a bit over 1.5 metres towards the left end of the track. I've designed this with three lanes in mind.

The wish list for this build is as follows:

1. Three lanes
2. Analogue
3. Working pit lane
4. Some scenery
5. Street circuit, loosely inspired by Monte Carlo.

The track would run clockwise, starting on the main straight at the bottom, through a sweeping turn, under the bridge towards a hairpin where the lanes would narrow to follow a more natural racing line. This would continue up a steady climb to a tighter hairpin, which I'd like to vaguely resemble the Mirabeau/Lowes section of the Monte Carlo track (see below, except my track will be climbing up rather than plunging down):



After the hairpin, the track would continue to climb up to a 90 degree right-hand turn before the bridge. Again, this series of bends will follow natural racing lines before widening to a more traditional scalextric style lane spacing over the bridge. This would continue through the fast turn after the bridge, along a short straight before again tightening to a racing line through a plunging, swooping section which I'd like to be something of a cross between Spa's Eau Rouge and the Corkscrew at Laguna Seca. The lane spacing will then, once more, widen, and lead in to the long final turn before the start/finish straight.

The track would need to split into two-metre long sections for storage. My main concern here would be that the pit building (which I will attempt to scratch build from foam board) would have to sit on the split between the two sections of the track and would therefore have to be two separate structures.

Has anyone else out there built a three-lane track of a similar size?
Should I instead be considering a two-lane track given the amount of space I have?
Any other feedback?

This is going to be a bit of a slow-burner, this one. I have a lot of tools and materials to buy before I can even think about starting work, and a rather limited budget. If I can get the plan nailed first, it would at least be a start!

Any feedback welcome!

Cheers
