G Gauge RailKing One Gauge Unibody Tank Car - Norfolk Southern. 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. Choice of Operating Knuckle or Hook & Loop Couplers. Unit Measures: 18" x 3/8" x 4" x 6".
