Plymouth Citybus have now published their promised new website, and indeed as has been hoped, it does look much more professional and very smart. As can be clearly seen the new PCB branding is very similar to that of the Oxford Bus Company's. As a comparison I've added a photo of their website below.
The information is largely the same but it is in a much more clear format than before. Unfortunately the timetables are still displayed in a pdf file rather than having it internet based, which can cause problems at times.
A feature of the website is you can now 'sign up' to PCB and receive updates automatically sent to your e-mail address. I believe in time you were therefore also be able to login to buy tickets online? It all does look very promising. But this promised unique identity does seem to be somewhat slipping away!
