Rule 57. The following signals will be displayed, one on each side of the rear of every train, as markers, to indicate the rear of the train: By day, two red flags; by night, at least two red lights.
In practice, besides the two red markers, a tail light like this would be hung on the train door of the rear car. The paint on this one was in very bad shape; I was able to get much of the box down to nearly bare metal with a shop vac.
The "CA&E Ry" label dates to 1946 or later.
And with a couple hours of work, it looks good as new. This one is missing its oil lamp mechanism, however; I'm hoping we have a working spare or two. Otherwise I can use one from a hand lantern.
