O Domino Sugar Tank Car

The
tank car was relatively uncommon until the 1870s, when the nascent
petroleum industry ordered large quantities of metal tanks carried on
wooden car bodies. By the early 1900s, a standard design had evolved
that lasted throughout the steam and early diesel eras: an 8,000-11,000
gallon metal tank perched on a metal flatcar-like underframe.
The one big change during that time was the transition from riveted to
welded construction beginning in the late 1930s. Car builders
introduced X-ray inspection of welds to ensure safety, as well as giant
annealing ovens that could heat-treat assembled tanks to relieve joint
stress. Welded tanks were stronger, less susceptible to rust and
corrosion, and less likely to rupture in the event of a wreck.
Our model represents a typical all-welded, insulated tank car built in
the late 1940s or 1950s. A layer of insulation protected cargos that
were sensitive to temperature extremes, and some such cars also had
heating coils under their outer layer. Our model also features a safety
platform around the dome – insulation and safety platforms being
features commonly found on cars used in the chemical industry.
