So yes, it does permit child fares but only when travelling to or from a school or college. I'm not too sure about what you mean about using it with the railcard, can you expand on this?

Well, I've always used my 16-18 photocard on the buses, never on trains. National Rail website makes distinction between child and adult disabled persons railcard, that got me confused for a bit until I checked my railcard it made no mention of that.
Reason why I asked this because I was bit worried if using adult disabled persons railcard on child rate ticket would make it an invalid combination.
