Caboose trucks
Cabooses were easy on trucks, as they were lightly-loaded
and received regular maintenance, but good riding qualities
were, for obvious reasons, desirable. In the first quarter of
the 20th century, most cabooses rode on arch bar or Andrews
trucks with elliptical leaf springs (51). Then, in the 1920s, the
Bettendorf Swing Motion caboose truck was developed. This
truck improved riding qualities and durability by combining
cast steel integral-journal-box side frames with leaf springs
