This article from about 70 years ago provides a good history of the line and it also documents the railway as its on-line coal reserves were soon to become obsolete as a locomotive fuel. It still had a good route for passengers travelling between Montreal and New York City in the years before driving and flying were financially within reach for most people.
My father's interest in this railway probably stems from his solo teenage travels to New York, during his father's summer Masters degree work at Columbia University.
At the end of the article are the DH magazine cover and a link to some of my father's artifacts from his travels.
This magazine was aged with care (as they all seem to be) in someone's 'railway cellar' in a cardboard box (I guess) for many years. I find that airtight plastic storage boxes are great for segregating and storing fragile vintage artifacts like this.
The finely-aged pulp paper magazine has this appearance (below) in its artifactual state. I've done an adapted 'white balance' to make the text easier to read. I've also tried to enhance and enlarge the photos in the usual manner.
