Locomotive performance data

[NW Mailing List]

 Good morning, all:

Railroads such as the N&W had dynamometer cars which captured such information in addition to water and coal consumption. The recorded data reflected track profiles and tonnage, which was sent to the railroad's locomotive engineering department. This card is the first I have seen with such data which is summarized for a month. Some annual reports include such information.

As information,
