Also has been 153s in passenger service with Northern - I can only remember one time though.
Another time a 153 came past was whilst one was going empty from Neville Hill to Kilmarnock Works so took the odd path via Newcastle & Carlisle.
Heaton have the odd 158 and 150 however these are normally there for big maintenance jobs, ie full overhauls etc.
These come up from Neville Hill, Leeds, via the ECML. No Newcastle or Heaton traincrew sign them (there may be one or two but this isn't enough to run a service with them).
