The current issue of Steam Days (February 2017) has a 10-page article by David Martin titled A Day Trip to Grantham: 1961, which starts on page 43.
David's description of his trip includes the journey by bus and train from his home in Clifton, Nottingham. This section of the article is illustrated by a highly evocative selection of images from the Rail Archive Stephenson collection (mostly taken by T.G. Hepburn), along with others from Tom Boustead, most depicting seldom-photographed locations.
Arriving at Grantham, many of the accompanying photographs are in colour by Keith Pirt, and two more of his pictures feature across the cover and the contents pages of the issue.
