The style ofrod fastened to front of end sill is the least efficient, while, ingeneral, the single-end rod on concealed end sill cars and thesingle-end rod on back of end sills give better service. Besidesthe data contained on attached sheets, a large number of un-coupling attachments were found having loose lag screws, rodsbinding on brake staffs, retainer pipes, ends of car, etc., andwith the handle improperly located. Answers to a circular letter sent out showed that excessiveslack in draft rigging is largely responsible
