Is the reference to 1759 based on your own observation, or just taken from BusTimes?

I ask merely because a previous post suggested that 1440 was tracking as "1759", and it would be useful to get some kind of confirmation.

(I think I also recall a post in another thread suggesting 1759 had been moved to Darlington, which, if this was a genuine observation, would certainly qualify 1759 on 64/64A as a "Rare & Odd Working"! )
