Not too sure what it is, but there's an age at which kids don't have the hand/eye co-ordination to control the things properly - they'll try to use it like an on-off switch (cue cars flying everywhere). something to be said for buying the micro sets...
For general info just google slot car, there's a lot of compatible makes - much of it really far too good to trust to kids
- the Scalextric stuff's generally a bit more robust and less realistic, depending on what it is (other brands SCX, Carrera, Nico, etc)
FWIW - the scalextric digital and sport (analogue) use the same track that's easier to assemble than the old stuff - and you can get connectors to link it to the old style track of 10(?) yrs ago - but the controllers/cars are different so can run cars in the same slot (there's overtake sections like railway points). You can retro fit the digital car controller into older cars tho'.
Dunno how well it runs, but one advantage with Micro scalextric is it takes less room - put out a decent amount of 1/32 stuff (ie 'proper' scalextric) and it takes a lot of room. Another lot worth looking at might be Tomy AFX (Argos *used* to sell sets) - smaller scale too (HO I think it's called) - mebe google for spares availabiltiy
Ah, thought SCX and Scalextric had some sort of tie up..kinda:

A couple of years ago we did a street party and I sorted the Scalextric (bloomin' kids, the adults never got a look in - someone should have packed em off to bed !) - found some good deals of little used track/sets on fleabay - now got a big pile of it in the spare bedroom
One lot I bought from via ebay and separately are http://www.lddiscounts.co.uk/ - occasionally there's good deals, esp of unboxed stuff.
I'd suggest you store any track somewhere that's nice and dry - that's possibly not the attic. I once left a set in the car boot overnight, just the condensation in the car brought out some rust spots ! The plating on the track's very thin and you really don't want to attack with anything much more abrasive than a duster...
Edit - I ought to add I'm not a slot-car anorak ! - I just do a fair bit of research before buying stuff
And you realise when the kids aren't around then drinking and driving is obligatory
