Based on the distinctive 50' Trinity RD-4 hopper, these modern open hoppers are an excellent choice for recreating unit coal trains, power-plant traffic, bulk commodity movements, and contemporary North American freight operations.\u003c\/p\u003e\n\u003cp\u003eTrinity RD-4 hoppers have been in prototype service from the 1990s to the present, giving modelers a broad operating window for modern layouts. Closely associated with high-volume coal transportation, these rugged cars have also been used for scrap and other bulk loads, making them useful additions to both dedicated unit trains and other heavy freight operations.\u003c\/p\u003e\n\u003ch3\u003e50' Trinity RD-4 Hopper Cars for Modern HO Scale Railroads\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eTrinity 50' RD-4 Hopper\u003c\/strong\u003e was designed for efficient movement and unloading of bulk commodities. These cars became particularly recognizable in coal service, where large fleets could be operated together in long unit trains moving between mines, loading facilities, railroad yards, and power plants.\u003c\/p\u003e\n\u003cp\u003eThe prototype's combination of rotary unloading capability and rapid-discharge bottom gates provided flexibility at unloading facilities. For model railroaders, the distinctive high-capacity design provides an instantly recognizable freight car for recreating the enormous coal trains associated with modern North American railroading.\u003c\/p\u003e\n\u003ch3\u003eDetailed Walthers Mainline Trinity RD-4 Models\u003c\/h3\u003e\n\u003cp\u003eWalthers Mainline recreates the Trinity RD-4 with a heavy die-cast metal underframe for improved operating performance along with separately applied door mechanisms, brake details, and interior bracing.
