You may have noticed LU's battery maintenance locos do have yellow panels...

Chickens and eggs? The choice of yellow may have been influenced by
the need to operate over NR tracks, and not just the obvious tube
routes, but occasionally, in the past, on other jobs.

LU service trains have traditionally been yellow, not just on the
front ends but all over. See for example the tunnel cleaning train.

I dispute that.

They were traditonally maroon or grey or green.

Yellow is relatively new, I'd be 99% sure they *never used yellow
until well after BR started. DL81 -83 came to Lu in ?1969 ? 1970 ? and
they were green not a shade of a yellow panel on them.

Yes, some have been yellow for a long time now, but ''traditional''
no.
