NEW FEBRUARY 2016. This was a brouchure for prospective customers who were considering installing a hump yard. It gives details appropriate for a technical non-specialist. Thus for retarders it goes into a description and drawings to show how they work, describes the options for their control and explains how they would be installed - a less straightforward exercise than might be expected.

The document is undated but was probably from the late 1940s. Topics discussed include the overall layout of such a yard, retarders, point control, control desks, track circuits, hump signals and power plant requirements. There are several photographs, and the file is word-searchable.
