Those who want factual data on these might be interested in downloading the rolling stock manuals which cover locos, passenger including suburban and long distance, freight and some service stock. The links below take you to the download site where the front cover of the document is displayed so you can see what the item is before you select the download button.
Links to the QR blue book diagrams in PDF format.
One is dated 1982 and the other 1991. Both about 9 MB.
