That would put a new angle on all those 'reality TV' shows.

I like the idea of not using an aerosol, so if you were to clean it out more, how would you do so? Warm soapy water or something else?

Two of the three can be seen on Grantham: https://www.rmweb.co.uk/community/index.php?/topic/58826-grantham-the-streamliner-years/&do=findComment&comment=1321315.

Does that mean you've seen what's in Tony's drawers, Mick?

Was there a speed restriction when slips were used on (main) running lines?

I'm not sure this will be of any interest to you but I have a layout which I built several years ago for my son using stuff I had knocking around. Here is a poor quality photo. It uses code 100 Hornby track with four Peco points (LH, RH & two double slips). Wired for DC with finger-operated points. The base is an IKEA 1.9m Lack shelf topped with insulation board. It is probably not up to the standards you are modelling to but it might provide an instant start and you could gradually replace the Superquick buildings. Let me know if you are interested. (I won't be offended if you aren't.) It isn't free, I am looking for a decent donation to charity. I am guessing from your username that you are somewhere near Telford so that isn't too far from me and I'm sure that once the weather improves a socially-distanced collection could be arranged.

Wickes? (£3 for 10kg)

I wonder if drilling some holes from underneath would enable you to put a little adhesive onto the underside of the weight?

It certainly is.

Yes please Mr Bacon. I'll email you.

Wasteful and puzzling. You'd think they would just use whatever they send track in. Mind you, a few weeks ago I received a similar sized box but perhaps just half the height. It came from Amazon even though I purchased from eBay. Inside was a pile of scrunched up brown paper surrounding a stout cardboard A4 envelope, inside which was the thin 30cm metal ruler I had purchased.

Another idea is home made plywood angle legs with holes for dowel pegs. Each leg made from two 500mm lengths of angle, overlapped in the middle. A block of softwood at one end of each angle would provide for fixing to the baseboard at the top and for an adjustable foot at the bottom for leveling. When removed for transport the pieces would stack inside each other. If this description is too vague then I can knock up a diagram.

These may provide some ideas even if they're not exactly what you are looking for. https://www.ikea.com/gb/en/p/olov-leg-adjustable-white-10264302/ I am sitting at a desk with four similar legs and they work well. You set the leg length and twist it to lock. It is a two person job to adjust the height though unless the desk is cleared and upended. https://www.ikea.com/gb/en/p/finnvard-trestle-with-shelf-white-80150095/ My son is an artist and has a large desk top sitting on a couple of these trestles. They allow the desk top to be set flat or at an angle. They are stable, strong and have a useful storage shelf. They are not particularly compact for transportation though.
