Operations Handbook - FoI request

In another recent Freedom of Information request, Cllr Zoe O'Connell asked Cambridgeshire County Council to "provide copies of all versions of the Cambridgeshire Guided Busway Operations Handbook, both current and past". The County Council's response makes the current edition, v.1.10.1 dated June 2017, publicly available. Earlier editions have been made available to Cllr O'Connell for downloading (as they're too large to attach to an email).

Here's a link to the FoI request, from where anyone can access the June 2017 edition of the Handbook:

Curiously, this edition, although postdating the opening of the Busway extension to Cambridge North station, provides no diversionary route should that section be blocked or otherwise unavailable for any reason.
