Reliability of Ashington's solos.
I've recently noticed that Ashington's solos have been incredibly unreliable and constantly braking down (2853 seems to be the worse of the lot for it). Ashington should send them back where they cane from and get the E200s back or some pulsars in return as Darlington clearly knew that those solos were a problem and took the first opportunity to dump them off on another depot.
