Live and learn.
Oh, well, who cares; it's worth it. It's a wonderful resource telling, as it does, the story of the various railroads that have run up and down the line. And the abundance of images of the equipment used by those railroads, particularly, of course, the Arcade & Attica, is just remarkable.
Apropos to the topic of this thread, there was a B. A. & A. combine in use on the A&A for the longest time, along with one other combine (from where I can't recall). In answer to my question, the book shows that the passenger cars used by the Arcade & Attica (as such) did not bear the name of the railroad on their letterboards. They were simply left blank.
What a shame that neither of those combines was preserved. The former BA&A combine was just gorgeous and the other was quite unique, as well. And all of those beautiful locomotives scrapped! Horror.
While glancing at the book last night, I noticed that a number of pictures of the excursion train showed that lanterns were hung on both sides at the head of the first coach and at the rear of the last. Also, the locomotive bore two white flags in its stanchions on either side of the smokebox. Those were nice touches. A little more attention to detail today as then would be nice.
