MTH 30-73402 O Gauge Wabash 3 Dome Tank Car #809070 VariantsUnitPrice_number_18.07 Model Number: 933-3090This is MTH 30 73402 WABASH 3 DOME TANK CAR. 3 dome tank car, Wabash. Car number: 809070. Three dome tank cars were actually three complete tanks on a single car body. Each tank had its own end bulkheads and expansion dome. Since older tank cars were filled to the top of the tank to prevent fluids from sloshing around during shipment (which could make the car unsteady), the domes provided space for the cargo to expand when the sun heated the tank.
