I can understand, given how new the 91s were at the time - but what you would give for something similar today!
It would be great and who knows what in todays railways turn up! Who knows if it had happened while Natex still had the route we may have ended up with stuff that works out of Liverpool St or Fenchurch St instead of them having to higher in off other operators.
Had a quick look at my photo last night but had no date on it looks like trawl through my old spot books. The only thing I can say is that it would have probably been a Saturday.
