The Black paint is light absorbing black, this is to prevent any reflection from the light beam located within.

Recently noted running with "Mentor" 975091, still carrying the part dark grey livery, presumably as a brake force runner.

This coach is used as a brake force runner, now that it has been replaced in the SGT with DBS 9708.

This small box is the modern version of optical car 460000 which I believe will soon be replaced.

Signalling bell code 5-5 may be used for this (train divided) even though it is clearly not, painting bodysides matt black at an angle to mask the yellow coach ends could help...

I thought that painting the vehicle ends matt black had something to do with abosorbing the light as well? Anyway it seems that the optical kit from 460000 has been whittled down to just this box, but there is a large gap between the two vehicles I must admit.
