Today you will hear and see how I built my HO model railroad, the Allegheny Central, for Operations. As you will see, the layout has been expanded over the course of the last 10+ years. Originally designed for 3/4 operators in a 52’ x 27’ basement, we now operate with 8/9 operators over the course of 2.5/3 hours every other week, from late September to early May. I will also cover my operating philosophy and the use of car cards and waybills, as you may find these useful in setting up operations on your layout.
