Speed-related correspondence - FoI request

It was only a matter of time before the recent batch of Freedom of Information requests spawned some follow-ups. There have been two in the past week or so, both submitted by Cllr Zoe O'Connell. In no particular order...

One of them requested from Cambridgeshire County Council "copies of any 'information passed on to bus operators' relating to speed checks on the Cambridgeshire Guided Busway, as referred to in your response to FOI request 8012" (covered by this blog in a posting dated 4 August).

 The County Council responded, saying that is "does not hold a record of this information. The reason there is no correspondence is because the information was passed on verbally to the relevant operator control rooms. The conversations were not recorded so no record is held of the times / dates or content of the telephone information passed to either operators in regard to speed checks."

So who knows what was said to whom, or when, or how frequently. Or anything, really...
