In response to numerous requests, we are pleased to offer a twelve pack of the Trinity ten panel BNSF hopper. BNSF has over 7,000 of these striking cars, and unit trains are seen daily snaking their way over the BNSF mainlines. To effectively model the BNSF, you?ll need a whole bunch of these cars, and HERE is where to start. Each car will have it?s own separate and distinct road number, different from any other car in the twelve pack.
