Talk:Great Northern W-1

Minimum curve
"Minimum curve 17 degrees (locomotive only) 10 degrees (with train)" seems wrong. Minimum curve for railroading usually has length units, feet or meters. Unclear what degrees mean in this context. Yet there is a source for that. John Nagle (talk) 03:58, 13 June 2017 (UTC)
 * Found a reference: "Curvature can be expressed in terms of the number of degrees traversed by 100 feet of track.". This is old terminology, but the W-1 is an old locomotive. John Nagle (talk) 04:09, 13 June 2017 (UTC)
