Remember, you can never have too larger wire size but too small can lead to problems.
If you do use the 7/0.2 and get occasional failure to throw issues, then simply double up all three wires to each of the motors.
For supplies try Brimal, Bitsbox, Rapid or even ebay all of which will normally be considerably cheaper than Maplin.

Well I popped over to Maplins this afternoon and checked out the wire. The 16 strand still looked smaller than the stuff I've been using so bought the 24 0.2m instead. It's not much dearer and rated at 6A so that should avoid any smoke

Whilst we are on this subject, do you have any advice concerning the use of copper tape as used in dolls' houses? I have never used it because I am too scared of a short. Do you know if copper tape is thick enough for point motors or should it only be used for lighting?

Don't know, never used it. I would guess though it would only be suitable for lighting inside buildings.

Does anyone know where you can buy twin flexible cable which can be used for dropper wires?

Twin flex! Why do you specifically need twin? Normally two single wires are used 16/0.2mm or if less than approx. 300mm rail to DCC bus then 7/0.2mm can be used.

Some speaker cables will come out at roughly this wire size if twin is really needed. But you would need to check before purchasing.
Examples... For short distance as above... twin 7/0.2mm
For longer dropper wire length... twin 13/0.2mm

Thanks FB - I wanted twin to keep the wiring neate but I had thought about flex so that is definitely an option. Not thought about the right gauge of speaker cable - that's (another) good call

Many thanks FB - that looks like a very useful site for electrical bits and you also asked my next question about speaker wire without me asking
