Bethgon II Coal Porter (remember: links to sub-pages at the bottom of this page) click to jump to the bottom These are due out shortly (as of May 2011) They look beautiful, and there are several improvements in the trucks over previous AML rolling stock. These are pictures of the pilot production run. Notice in the picture below, the new wheels and axles. The old AML wheels were sintered (pressed powdered steel) and and a rough tread surface. The new wheels have nice new smooth treads, and are CNC machined. Also see the nice thick stainless steel axle. All of this helps keep the weight near to the rails too. The roller caps rotate with the wheels, and the new trucks are sprung: The picture below shows the separately attached brake detail, sorry for the poor picture, they look much nicer in person.
