No black LEDs?

I recently spotted Geoff Marshall's unboxing of this live animated LED Tube
map, which shows all LU train movements in real time. Trains on 12 lines
are represented with 333 appropriately coloured station LEDs, but how do
you represent Northern Line trains? Yup, in white.
Just the thing for a Tube nerd with £249 to spare! An ideal present for
someone who grew up in London but now lives in exile.
Looks to me like it only shows trains in stations, not all trains on the line.
I'd be interested in knowing where it gets its info from. Is it a public
API anyone can connect to or is it paid subscription included in the price
of the board that will eventually run out.
