Does anyone know anything about the details about the BESI (Bus
Electronic Scanning Indicator) sytem and how it worked? Other than it
based on barcodes and scanning heads?

Each bus had a bar-code and a laser scanner on a concrete post (you can
see it in the photo) to read the code.

Funny this. Many years ago MR had an item about how
BR were putting bar codes on the side of their locos to be
read by static scanners so that they could keep track (oops)
of their stock.

It was in the April edition.
