|The purpose of the datasheets is to bring together in a tabular format all the known information relating to wagon numbering, build details and design codes. It is intended to add more datasheets over time, each one covering a particular TOPS code group. However, the research required is such that the rate of additions will probably be quite slow. There are also limitations due to the availability of information such as early TOPS design codes and AARKNDs. If you are able to add to (or correct) any of the information on these datasheets, please use the Feedback button at the bottom of each page to contact me.
Later on, datasheets may be published as Acrobat PDFs, either singly or in collections, to allow downloading.
The table below lists all datasheets produced to date, in order of TOPS code. Links to the sheets can also be found in the Code column of the TOPS code listings pages.
