I don't recall our school train ones getting that- they were very old with the original string luggage racks.
Had iirc just two low wattage bulbs for lighting too- which naturally we used to unscrew in Sevenoaks tunnel.
It depends which era you're talking about. Pre-1988, no, but I am fairly sure they all got red stripes pretty soon after this incident. That is, unless it was unit 5001, which was repainted into SR green. That was the one unit that kept its original formation until the end, with one saloon and one compartment trailer, and it was on the last public working, the 20.02 Charing Cross-Dartford via Sidcup on 31st March 1995, coupled to the BR blue unit 5176 (which I was on!).
Funny you should mention about unscrewing the light bulbs - I grew up in Putney, and went to secondary school in Richmond from 1986-91. By then the EPBs had all gone from the South Western Division, so I mostly travelled to school on 455s, but once I had a VEP, and travelled with some of my mates in the one standard class compartment which at that time still had reading lamps. After a while my mates started unscrewing the bulbs from those, and unfortunately planted one of them on me in a carrier bag full of ingredients that I had for a cookery lesson. I rummaged in my bag for it, and accidentally knocked it out onto the floor and broke it - not that I meant to do that, of course! But had I been only a few years older, they and I could have faced a painful visit to the headmaster or headmistress even if it was their fault not mine!
