an "AB cylinder" or does that designation refer only to the controlthe
use of what appears to be a "K" cylinder in the Red Caboose X29 ABBruce,
The AB brake is made up with a center a center section (the PIPE

This required the two stage reservior and a separate brake cylinder.
The cylinder would have look very similar to the split K arrangement.
