SD40 Article in Arrow

[nw-mailing-list at nwhs.org]

All;

I guess that I figured most everyone would understand that the "triple clasp 
truck" has three sets of clasp brakes per side frame. With that design, a 
single brake cylinder is needed to actuate the brake pads via the 
appropriate mechanism. The NS Locomotive Equipment Guide (from NS) does call 
this brake system a "clasp" system, as opposed to a single-shoe system, 
which would be found on the former Southern SD40-2's.

The use of the term triple clasp brake was not intended to infer that the 
brake rigging had three brake shoes per wheel.

Regards,
Russ Goodwin
