I wrote to them following a discussion on why the 10:15 from Cambridge to
King;s Cross has been changed to the 10:20 which is often checked by NXEC
services at or South of Hitchin:

I have to say I still find it disappointing that the Cambridge clock
face pattern was further eroded for this reason when the East Coast
timekeeping barely justifies it and makes performance worse.

They replied:

Thank you for contacting First Capital on 19 September 2008
regarding the clock face at Cambridge station.

We can only answer customer enquiries about our trains and
facilities as Cambridge station is operated by National Express
East Anglia, I am unable to provide a full response to the points
you have raised. In order for this to be investigated I have
forwarded your correspondence to National Express East Anglia at
the address below.

Doh!
