And the fact that approach signals are replaced by track circuit
occupation, and Repeats aren't.

Note to Matt: Flashing aspects are supposed to be flashing
aspects. I havn't looked through my notes to see what the flash
rate is supposed to be exactly, but it's accomplished usually in
a few different ways, none of them adjustable.

Seeing as I'd only heard of this existing at Stuart (?) As I
recall it was to 'tweak' the driver into remembering to pick up
the staff. It wasn't a wide spread practice.

Speaking of strange practises, we almost had purple aspects as
well (for repeats), only I couldn't find a manufacturer. All of
the aspects I ever found looked blue.

Seeya!
