Brilliant and using the formation guide just shows the marketing ploy for the gen brake, I look forward to buying 2 of these, bound to happen as I was about to add some white lines on a model tomorrow, having gained a free day.
I suspect the high spec model will come with a sound facility built in even on DC and perhaps a wand switched taillamps - plug in accessory , but DCC version will have guards conversations, door slams and gen start up stuff. Now for a smoke unit!! - that can be retro into the new NIR stock and the soon to be announced MK1 EGV sets ..... April announcement dates I guess.
