Jim,
I was under some impression this was the(maybe inugural trip) Fishtrain. I'd expect a few more cars for a Morrison train service.
A Combine to handle the catch and accomodate the patronage, and note the "dress" seems to be for an outing in the wilds opposed to fashionable for an outing to town.
Whatever the occasion was that presented, Charter or Scheduled service, that has to be the neatest ever.
