Busway service "shot at"

I realise this is close to being "old news" by now - in my defence I've been out of the country... - but there's a report on Cambridgeshire Live of a Somersham-bound D service being hit by a shot from an air rifle on the evening of 10 October. Now it's a little unclear whether this was, indeed, an air rifle shot, or some object thrown at the bus. But whatever it was caused damage to the bus, in the form of a broken window, and alarmed some of those onboard. The incident appears to have happened between Oakington and Longstanton.

Passengers were transferred to a following service.

Route diversions on Sunday 21 October

Due to the Town & Gown 10k Run on 21 October 2018, Stagecoach will be unable to serve many stops across Cambridge City Centre. For busway routes A and B, than means no buses will be unable to serve stops located on New Square, Jesus Lane, Castle Street and Shire Hall.

Passengers are advised to board at Drummer Street bay 12.

Whippet to withdraw Busway Service 'C'

In a shock announcement, contained in this CEN news report (along with news of the loss of the Whippet X3 bus), Whippet is to withdraw its independent busway service 'C' from November 10th. (Service 'U' remains.)

There are no reports, as yet, of either closure on the Go-Whippet website.

Extract: << A spokeswoman for Cambridgeshire County Council said: “Whippet have made the commercial decision to withdraw the C and X3 services from 10 November. We are currently discussing with other operators whether they can provide a replacement service of some kind. We will let residents know the outcome of these discussions as soon as possible.”
Whippet was approached for a comment but was unable to give an official statement at this time. >>

Was this inevitable?
