Floor mat for OO track

[essayer]

Any recommendations for grippy matting that I can temporarily set out a small Hornby layout on (it’s for the kids, honest, they’re not yet trusted with a permanent setup) - running on carpet isn’t ideal as the track moves in use!

No, not plywood.

Interlocking floor tiles?

Take care running the train on carpet, the fluff will get into the motor mechanism

Vinyl carpet protector?
