One for the destination experts:

What do we think of trentbarton? Their destinations are usually very clear, but they rarely comply to PSVAR guidance.

There's barely any route numbers to speak of. The display will often switch between the destination and the route brand; sometimes including descriptions such as on the red arrow 'Derby FAST'.

Then there's the issue of colour. On the Spondon Flyer, the two variations of the route are denoted by a green or blue circle where a number would usually be. On occasion where a route has a number, such as 'the two' the number is spelled rather than displayed as a digit.

All in all, it would be difficult to argue they are not being clear with their equipment. AlthoThe unconventional, I would argue they really make the most of their equipment. Do their efforts, however, make it (very) technically illegal?
